Every sustainability conference that matters, in one place

Tickets: Full Conference Pass rates rise across four windows: Best (6/3-6/30), Early Bird (7/1-7/31), Standard (8/1-8/28), and Full (8/29-9/3). Corporate/Individual: USD 1,975 / 2,275 / 2,475 / 2,675. Government/Non-Profit: USD 1,275 / 1,400 / 1,500 / 1,700. Green-e Participant: USD 1,775 / 2,075 / 2,225 / 2,325. Student: flat USD 495 in every window. 1-Day Pass (Wednesday or Thursday): USD 990 / 1,100 / 1,200 / 1,350. Pre-conference training add-ons run USD 105 each for Renewable Fuels 101, U.S. Renewable Electricity Policy 101, Carbon Offsets 101, and Voluntary Renewable Electricity Markets 101, while Green-e 201 is USD 55. A bundle of all five is USD 375. Groups of 3-plus registrants get an automatic 10% discount. Prices are in USD with no VAT, as this is a US event.

Who's there: Leaders from federal and state governments, major corporate purchasers, top US utilities and electricity generators, policy experts, and renewable energy marketers, per organizer copy. The organizer's published attendee-profile categories are Energy Seller, Developer, NGO, Corporate Purchaser, Government/University, Service Provider, Consultant, Broker, and Media. The 2025 edition, the most recent held and the last verified actual, convened 350-plus attendees from more than 230 organizations. The organizer publishes a "select previous sponsors" roll rather than a 2026 sponsor list; names on it include NextEra Energy, Xpansiv, PJM, WGL Energy, Google, LevelTen Energy, 3Degrees, AES, and MSCI.

Room: 2025 edition (last held, verified actual, per organizer sponsor page): 350-plus attendees from more than 230 organizations. No attendance figure has been published for the 2026 edition since it has not yet occurred.

Worth knowing: Standard-rate pricing ends Aug 28, 2026, and Full Rate applies Aug 29 through the event. Refunds are already closed: cancellations received Aug 19, 2026 or later get no refund, and cancelling registration does not cancel the hotel booking. Confirm you are booking the US edition at renewableenergymarkets.com/us, since the organizer's site is split by region.

Tickets: General in-person tickets are sold only via Eventbrite (GBP, no-refunds policy per Eventbrite's own terms), but the price itself did not appear in the static event page or the Eventbrite listing content that could be fetched, only inside Eventbrite's dynamic checkout widget, so no figure could be verified. The one confirmed price is the Media Pass, which is FREE but restricted to credentialed media.

Who's there: Corporate CSOs, heads of sustainability/ESG, and sustainability strategy leads from large enterprises. Confirmed 2026 speakers include eBay, Experian, BBC, Google, Amazon (AWS), Currys, VodafoneThree, Toyota Motor Europe, Finnair, Nestle Waters, and Odfjell. Co-located with a procurement and supply chain buying audience.

Room: 1,000+ in-person attendees, 50+ speakers, two-day conference and expo with 10 content tracks and 4 executive workshops (organizer-stated figures). Co-located with Procurement & Supply Chain LIVE: The London Summit + Awards. A separately ticketed Sustainability LIVE: The London Awards dinner runs the evening of 8 September at the JW Marriott Grosvenor House, London, not the QEII Centre.

Worth knowing: Venue changed for 2026: a July 2025 organizer article still referenced the event 'returning to the Business Design Centre,' but the live 2026 event page and Eventbrite listing both confirm the venue moved to the QEII Centre, Westminster, with Eventbrite explicitly noting 'but this year at the QEII Centre, London.' Sponsor roster (EcoVadis, Watershed, Altruistiq, Datamaran, SkyNRG, Greenly, IRIS CARBON, Sedex, Business Stream) supports the wide niche spread listed above rather than any single vertical. The organizer describes the event as hybrid, but only in-person tickets are on public sale.

Tickets: Visitor entry is free: the registration page states "Register and enjoy FREE entry!" with no ticket tiers, currency amounts, or early-bird deadlines. That is the standard model for this fair, where exhibitors pay for stand space and visitors attend at no charge. The official pages do not say whether conference sessions are covered by the free visitor badge. Exhibitor stand pricing is not published either; exhibitors submit an application through the site and receive a quote from the organizer.

Who's there: Organizer targets for the 2026 edition: 560+ exhibitors from 30+ countries, 25,000+ visitors, 45,000 sqm of exhibition space, 200+ expert speakers across the 3-day conference, and 2,200+ scheduled buyer-seller meetings. The show runs 10 special zones (including ULB/municipal, e-waste, startups, bio-energy, and textile recycling) and 6 international pavilions (China, Germany, Italy, Korea, Norway, Netherlands), so expect a mixed municipal, industrial, and international-exhibitor crowd.

Room: The organizer projects 560+ exhibitors and 25,000+ visitors for the 2026 edition, which has not yet been held. The prior edition, held October 14-16, 2025 at the same venue, recorded a verified all-time high of 18,000+ visitors per the official post-show review page.

Worth knowing: The official site is ifat-india.com. The prior edition ran in October; the 2026 edition has moved to September 9-11. Opening hours are 10:00 to 18:00 on September 9 and 10, and 10:00 to 17:00 on September 11.

Tickets: All rates are in Hong Kong dollars and rise across three windows. Standard pricing runs 4 August to 31 August 2026: Delegate full access HK$1,500 for both days or HK$1,200 for one day, Expo-Only access for both days HK$149 (entry from 13:00), and a Vendor Pass at HK$2,500. Last-minute pricing runs 1 September to 9 September at 20:00: HK$2,000 two-day delegate, HK$1,500 one-day, HK$250 expo-only, HK$3,000 vendor. On-site pricing on 10-11 September: HK$2,500 two-day delegate, HK$1,800 one-day, HK$250 expo-only, with no vendor pass sold at the door. Optional top-ups are the Day 1 networking event at HK$696 (HK$750 on-site), open to full-access holders only, and a happy hour drink for expo-only holders at HK$99, rising to HK$200 last-minute and HK$220 on-site. The Investor Pass sits at the delegate full-access rate with a full refund subject to terms. All prices are subject to an admin fee; Hong Kong levies no VAT or sales tax.

Who's there: The prior edition (6th, September 2025) drew 9,500+ attendees. Site copy describes the audience as business leaders, sustainability practitioners, and the people who research and resource net-zero and ESG strategy. The 2026 sponsor roster runs past 50 logos and includes DHL, Prudential, Zurich Insurance, CLP, Towngas, Cathay Pacific, AWS, ERM, ISS Corporate, HAECO, Jardine, Jardine Schindler, Marriott International, Siemens Mobility, New World Development, Swire Properties, Hongkong Land, Hang Lung, Kerry Properties, Nan Fung, InvestHK, and the Urban Renewal Authority. Seven pass types (Delegate, Expo-Only, Vendor, NGO, Student/Volunteer, Investor, Media) point to a mixed room of buyers, vendors, investors, and policy people rather than a single persona.

Room: The organizer reports over 9,500 attendees at the prior event (2025, 6th edition). The 2026 edition is the 7th, and site copy says it is expanding further, but no verified 2026 attendance figure exists yet since the event has not occurred.

Worth knowing: Venue is Hall 1, Level 1 of the Hong Kong Convention and Exhibition Centre, Wan Chai North. Standard rates close 31 August 2026, after which last-minute pricing adds HK$300 to HK$500 per delegate pass and the on-site rate is higher again. Published rates exclude the organizer's admin fee, and the pricing grid is posted only as an image on the Passes & Pricing page, so confirm the current figure at checkout.

Tickets: Standard conference pass is $2,699 (USD, rate effective from July 25, 2026). Add-ons cannot be bought without a conference pass: $999 for the SAF Focus Day, $699 for the RINs/RFS/CFR/LCFS Workshop, and $249 for the Golf Experience. Groups registering together receive up to 20% off the pass rate. VAT status is not stated (US-based event).

Who's there: Organizer materials state 500+ attendees, 250+ companies, and 15+ countries represented, spanning regulators, government agencies, airlines, biofuels producers, obligated parties, and carbon market participants. Named 2026 speakers include Washington State Senator Marko Liias, the Cap-and-Invest Auctions and Market Section Supervisor at the Washington State Department of Ecology, the Senior Climate Policy Advisor and Clean Fuels Program Manager from Oregon DEQ, and SAF leads from Neste and Alaska Airlines.

Room: Organizer materials state 500+ attendees and 250+ companies for the summit. No independently verified per-edition attendance figures are published.

Worth knowing: One-to-one regulator meeting bookings opened on the event networking platform on August 24, 2026, first come, first served, so anyone registering now competes for whatever regulator appointments are left.

Tickets: USD, and the pricing page reviewed states no early-bird deadline: AEE Members $995; Non-Members $1,195; Government/Non-Profit $1,095; International (outside continental US) $495; single-day passes (Wed/Thu/Fri) $595 each; discounted student registration available via a separate link. Expo-only access is free (list price $95, currently waived). VAT not applicable (US event). Cancellations require 14 days' written notice, minus a $95 administrative fee.

Who's there: Per AEE's 2025 post-event report, roles break down as Energy Manager/Engineer 23%, Energy Consultant 22%, Executive (CEO/President/VP/Owner) 15%, Sustainability/Renewables Manager or Director 7%, Sales/Marketing 6%, Business Development 6%, Facilities Manager/Building Operator 2%, and Other/Student/Retired 19%. The crowd skews 45+ (62%) and male (77%). Sectors represented include commercial, industrial, institutional, municipal, government, utility, energy services, and education.

Room: 2025 actuals (Atlanta): 1,450 attendees, 86 exhibitors, 48 countries represented, 160 speakers, and 40 sessions across 10 tracks. Organizer's stated target for 2026 (Orlando): 2,000 attendees, 100 exhibitors, 60 countries represented.

Tickets: Visitor tickets are free via online registration (forms.reg.buzz/ess-expo-2026). RWM Connect, a separate paid evening event on 16 September with 900+ attendees, needs its own ticket. Neither its price nor exhibitor stand pricing appears on the pages reviewed.

Who's there: In 2025, RWM drew 13,379 attendees, described by the organizer as waste management directors, sustainability leads and procurement decision-makers from local authorities, waste and resource management firms, manufacturing, facilities management and retail. The wider co-located ESS Expo group cites 16,000+ active buyers across all seven shows. No RWM-only seniority breakdown or named-account list is published.

Room: RWM reported 13,379 attendees in 2025 (organizer-reported actual). It runs alongside six other co-located ESS Expo shows (CARS/MRE, EFD, CLR, GEO, WWEM, AQE) on the same NEC Birmingham show floor, so site-wide footfall is higher than the RWM-specific figure.

Worth knowing: RWM shares its show floor and free-ticket registration with six other ESS Expo events on the same two days, so one free ticket also gets you into adjacent shows like Energy, Fuels & Decarbonisation Expo (EFD).

Tickets: No ticket price is published for The Hub Live or the Opening Ceremony. Access runs through a Cvent application that Climate Group approves within one to two weeks, capped at two people per organization, or through Climate Group membership, which skips the application. The attend page says 2026 is the first year Hub Live access is ticketed but names no figure, and the FAQ still describes both elements as invite only with free online streaming, so treat the cost as on request. Most of the 1,000+ independently hosted Events Program sessions are free, though individual hosts may charge their own entry fee. Hosting your own official event costs $1,200 per event for for-profit companies and $300 for nonprofits, schools, community groups, and government bodies, billed only after your event is approved. Event registration for 2026 closes Monday, August 31, 2026, and later submissions are considered case by case at the same pricing.

Who's there: 2025 Hub Live figures (organizer-reported): 2.5k+ attendees from 85 countries, 83% in senior roles, 1.7k+ organizations represented. The broader citywide Events Program is open to whoever hosts or attends one of the 1,000+ independently organized sessions, so its audience varies by session and is not centrally profiled.

Room: 2025 Hub Live (organizer-reported, not independently audited): 2.5k+ attendees, 85 countries, 83% senior roles, 1.7k+ organizations. The 2025 citywide Events Program separately listed 1,000+ sessions drawing 100,000+ attendees (organizer figure). Neither number is broken out for the 2026 edition yet.

Worth knowing: The Hub Live and Opening Ceremony sit behind an application, capped at two attendees per organization, and 2026 is the first year Climate Group has charged for Hub Live access. Most sellers will engage through the wider Events Program, either by paying to host an official event or by attending sessions other organizations run across the city.

Tickets: Fees are quoted in USD on IETA's public registration page. The Delegate Pass is USD 899, stated as carrying no VAT, and covers the venue for the full event including the Sept 22 NACS Welcome Reception. IETA members, government representatives, NGOs and academia get USD 200 off with a code from [email protected]. The IETA Nightcap Party on Sept 23 needs a separate USD 99 ticket, bought on its own or added to a delegate order. Press passes are free with a code from the same address. Payment is credit card in US dollars, passes are non-transferable, and no early-bird deadline is published.

Who's there: IETA describes the event as drawing hundreds of delegates spanning government officials, carbon market analysts, and industry practitioners, with no independently verified attendance breakdown published. The 2026 sponsor roster runs from the American Forest Foundation at platinum level through 1PointFive, Fastmarkets, S&P Global Energy and Verra at gold, LRQA EcoEngineers and OPIS at silver, and API, Beveridge & Diamond, Cool Effect and StoneX at bronze. That mix puts carbon project developers, registries, traders, price reporting agencies, and compliance-market service providers in the room. ICE and Verra both run their own program sessions on Day 1.

Room: No attendance figures are published for past or upcoming editions. IETA's own event copy says 'hundreds of delegates from North America and beyond' without a specific count. The main summit runs two days (Sep 22-23), preceded by a members-and-invite-only pre-day of offsite meetings on Sep 21.

Worth knowing: The Sept 21 pre-day of member and invite-only meetings runs at various offsite venues, separate from the main Sept 22-23 summit. The Sept 22 Welcome Reception comes with the delegate pass. The Sept 23 IETA Nightcap Party has limited capacity and a separate USD 99 ticket, with physical invitation cards collected at the registration desk before 18:00 on Sept 23. Venue is Convene 360 Madison, 360 Madison Avenue, New York, NY 10017. The event runs the same week as Climate Week NYC and UNGA.

Tickets: The General Attendee Pass is complimentary on request; as of Aug 27, 2026 the register page no longer states a closing date or late-ticket price for it, though a September 4, 2026 cutoff was previously published. The Executive Pass, adding a private lounge, AI-driven matchmaking, invite-only speaker Q&As, and priority seating, is $1,200. The Media Pass is free by application. Startup passes range from a $1,000 Gold Pass to a $7,500 Deluxe package (three-day kiosk, stage pitch, and three Gold Passes); a one-day kiosk package is $3,500 and a stage-pitch package is $4,500.

Who's there: The event's own copy states 10,000+ attendees for 2026, spanning corporate sustainability leaders, startups, policymakers, and investors across its six tracks. Confirmed 2026 speakers include Johan Rockström (Potsdam Institute), Josh Parker (Head of Sustainability, NVIDIA), Kathleen McLaughlin (EVP and Chief Sustainability Officer, Walmart), and Ryan Gellert (CEO, Patagonia). Title and Gold sponsors include GM, Verizon, S&P Global, Siemens, and JPMorgan Chase.

Room: The Nest Campus states more than 10,000 attendees for 2026, an organizer projection for an event that has not happened yet. No independently verified post-show figure exists.

Worth knowing: The 2026 edition is branded The Nest Campus; the older Nest Climate Campus name persists in the web address and some legal copy. The homepage and register page use live counters for attendee, speaker, and country totals that render as 0 in a static page read, so this entry uses the 10,000+ figure stated directly in the page's meta description and sponsor copy. An 'Executive Pass Flash Sale' banner referencing an August 7 deadline was still displayed on the site well after that date. Treat that discounted price as expired and the standing $1,200 Executive Pass price as current.

Tickets: 4-Day Ticket: EUR 199 online / EUR 289 on-site. 1-Day Ticket: EUR 98 online / EUR 159 on-site. Friday-only Ticket (25 Sep): EUR 39 online / EUR 42 on-site. 1-Day reduced ticket for students, apprentices, and people with severe disabilities, valid Tue-Wed only: EUR 20 either way. Free 2-day ticket for the same reduced-fare group, valid Thu-Fri only. All prices are gross and include 19% German VAT. Buying online in advance also includes fast-track entry and a free HVV public-transit day pass on the event day.

Who's there: Trade visitors, decision-makers, and young professionals from around the world, per organizer copy. The 2024 edition, the most recent one held and the last verified actual since the event runs every two years, drew 1,600 exhibiting companies from 40 countries (60% onshore, 40% offshore) and roughly 43,000 total attendees from 100 countries, across 83,000 sqm in 11 halls with 30 national pavilions. Exhibitors quoted by the organizer include Enercon, Alterric, SANY RE, XERVON Wind, Prokon, Siemens, and Vestas. Alterric's quote names business partners, property owners, banks, and financiers among the buyers it meets on-site.

Room: 2024 edition (last held, verified actual, per organizer post-show figures): 1,600 exhibiting companies from 40 countries and roughly 43,000 total attendees from 100 countries. WindEnergy Hamburg runs every two years, so no 2026-specific attendance figures exist until that edition takes place.

Worth knowing: The event is biennial. 2024 was the most recently held edition, so the size figures above are the last verified actuals rather than an organizer target for 2026.

Tickets: The standard Visitor Pass is free and covers 3-day exhibition access (including co-located EVCharge Live UK), full session access, and basic event-app features. The Premium Visitor Pass adds the full attendee list and unlimited 1-2-1 meeting booking for GBP 990, discounted to GBP 690 if booked before 28 August, plus a GBP 50-plus-tax admin fee. Infrastructure operators, housing associations, and public-sector buyers can apply for a separate free pass with VIP lounge access, subject to Terrapinn's approval. Listed prices exclude any applicable taxes.

Who's there: Terrapinn reports 20,000+ registered attendees, the same figure it uses to promote the 2026 edition, along with 500+ exhibitors, 250+ speakers, and 30+ partners across a 40,000 sqm hall. Site copy frames the crowd as installers, developers, and buyers who come to "investigate, assess and purchase" solar and storage products across residential, C&I, and utility-scale segments. No seniority or job-title breakdown is published.

Room: Terrapinn's site states over 20,000 solar and storage professionals registered for the prior (2025) edition, and it repeats that figure on the 2026 event page alongside 500+ exhibitors, 250+ speakers, 30+ partners, and 40,000 sqm of floor space. All of these are organizer-published; no independently verified 2026 actuals exist yet, since the event has not occurred.

Worth knowing: The GBP 690 Premium Visitor Pass discount cited on the registration page covers bookings placed before 28 August 2026. From 28 August, expect the full GBP 990 rate plus the admin fee.

Tickets: Full Conference and Expo, member rate: $950 early bird (May 5-Jun 28), $1,180 standard (Jun 29-Aug 23), $1,255 onsite (Aug 24-Sept 30). Non-member: $1,335 / $1,710 / $1,785 for the same windows. Expo-only passes run $150-$375 by tier and membership. Reduced rates apply for academic, professional operator, and young professional WEF members ($675-$855); WEF student members attend free. The onsite rate window now applies. The August 26, 2026 cancellation deadline has passed: refunds are no longer available, and any cancellation now forfeits the full registration fee.

Who's there: WEF states more than 23,000 water professionals attend from over 100 countries, and that 70% of professional attendees influence purchasing decisions at their organization. Attendees are mostly utility engineers, plant operators, municipal buyers, and consultants. Sponsors and exhibitors include Xylem, Grundfos, Schneider Electric, Autodesk, and Jacobs.

Room: WEF states more than 23,000 attendees from 100+ countries, 950+ exhibitors (a separate attend page on the same site cites 1,000+), and 125+ technical sessions. These are organizer figures for the WEFTEC series generally. The 2026 edition has not happened yet, so no independently verified post-show actual exists.

Worth knowing: The early-bird window closed June 28 and the standard window closed August 23, 2026. The onsite rate, good through September 30, is the current price.

Tickets: Admission is free for both in-person and online participation; no paid sponsorship, exhibit, or delegate tiers are listed on the official event page. In-person registration opens 2 September 2026, about a month before the event, and seats must be booked in advance. Online participation registers separately through a published Zoom webinar link that is already open.

Who's there: Keynote speakers are Johan Rockström of the Potsdam Institute for Climate Impact Research and Naoko Ishii of the University of Tokyo, with Chris Wheat of America Is All In as guest speaker and Japan Climate Initiative co-representatives Sergio Shigeo Kato and Takejiro Sueyoshi opening and closing the program. Panel discussants come from NTT DATA, E3G, the Renewable Energy Institute, Unilever Japan, Toyooka City, Kirin Holdings, WWF Japan, Daito Trust Construction and CDP Japan. No attendance figures, venue capacity, or attendee job-title and seniority breakdown are published. The organizing body, Japan Climate Initiative, is a coalition of Japanese companies, local governments and NGOs committed to climate action.

Room: No attendance figures or venue capacity are published by the organizer. The event runs as a single afternoon program from 2:00 to 6:00 PM JST, with room access from 1:15 PM, in one conference hall at United Nations University, followed by a networking session for in-person attendees. The online option runs through a Zoom webinar with no published capacity.

Worth knowing: On-site registration only opens 2 September 2026, roughly a month before the summit, so sellers wanting an in-person seat should watch for that registration link rather than trying to register now. The online Zoom option is open immediately, but the post-program networking session is limited to in-person attendees, so remote participation costs you the part of the day where conversations actually happen.

Tickets: Congress fees are quoted in GBP, exclusive of 20% UK VAT, and scale by IWA membership and country income classification (HIC/LIC) across four registration windows. Earliest tier: HIC non-member £1,090, HIC member £990, HIC student £400; LIC non-member £660, LIC member £600, LIC student £240 (all plus VAT). The final window, October 1-8 (effectively onsite), rises to HIC non-member £1,630 and HIC member £1,500 (plus VAT). A Gala Dinner add-on is £90 (HIC) or £50 (LIC), plus VAT. Trade-visitor-only exhibition access is free.

Who's there: IWA projects over 10,000 participants from more than 100 countries for Glasgow across the Congress and Exhibition combined, an organizer target well above the roughly 1,461 congress participants its own site reports for the 2024 Toronto edition. The projected room spans utility leaders, academics, government and NGO representatives, technology providers, consultants, and media. Principal sponsor is RSE; platinum sponsors are Grundfos and Xylem.

Room: IWA projects over 10,000 participants for Glasgow 2026 across the Congress and Exhibition combined, an organizer target for an event that has not happened yet. The official homepage cites the prior 2024 Toronto Congress at roughly 1,461 congress participants with 53 exhibitors, while a separate page on the same site shows different, apparently partial, figures for the same edition. Treat exact past attendance as directional.

Worth knowing: The official site shows inconsistent past-attendance figures for the 2024 Toronto Congress on different pages. Treat any historical attendance number sourced from the site as directional rather than exact.

Tickets: As of Aug 27, 2026 the event page no longer shows 'Registration Opens Soon' and carries a live Register CTA, but no ticket price was published as of that date, so confirm the live price before quoting one. EMA's membership page implies a non-member pass value of roughly $1,895, with members paying about $900 less (Green Individual membership at $2,000/yr lists '$900 off non-member'), an implied figure, not a quoted price. Published 2026 sponsorships: Diamond $15,000 (6 passes), Platinum $10,000 (4), Gold $7,000 (3), Silver $5,000 (2), Bronze $3,000 (network break, only 3 slots). Hotel block $259/night through Sept 9.

Who's there: Compliance market intermediaries: exchanges and trading firms (Marex, Nodal, ACT Commodities, ClearBlue), regulatory attorneys, state officials, and verifiers. Almost no corporate sustainability or procurement buyers and no VCM project developers appeared on the 2025 agenda.

Room: Record 165 attendees at the 2022 in-person return (actual). The 2025 Boston edition was marketed as expecting 200+ (organizer target). No 2026 count is published.

Worth knowing: The event page has swapped its 'Registration Opens Soon' banner for a live Register CTA, but no ticket price was published as of Aug 27, 2026, so confirm the price with EMA before budgeting.

Tickets: Buy-side pass free (asset managers, banks, PE, institutional investors, self-declared and gated). Vendor pass £1,499 ex-VAT (about £1,799 gross), flat, no early bird. Sponsorship tiers (Gold/Silver/Bronze) are unpriced and are the real route to meetings and stage time.

Who's there: Buy-side financial services, senior and verified: PIMCO (Head of ESG Portfolio Management), Morgan Stanley IM, L&G, Fidelity, Citi, Lloyds, and MetLife IM on the 2026 roster, with Goldman, JPM AM, HSBC, UBS, and Schroders attending in 2025. They buy ESG data, ratings, analytics, reporting software, and fund regulatory advisory. No corporate sustainability teams attend.

Room: '350+' is a marketing constant repeated across editions, not a measured actual. Expect a few hundred attendees across 3 streams and about 25 sessions.

Worth knowing: Venue moved to Hilton London Bankside for 2026 (2025 was Tower Bridge). The vendor checkout page still shows a stale '2025' SKU, so confirm details by email before paying.

Tickets: SWE only 899 euros ex-VAT; all-access, covering both SWE and the co-located grid summit, 1,099 euros ex-VAT. Flat pricing, no early-bird ladder, no published expiry. 80% refund only until about Sep 8.

Who's there: The strongest corporate buyer room in this guide: named 2025 attendees include Nestle, Unilever, Henkel, Diageo, Ferrero, H&M, Adidas, Coca-Cola Europe, Philips, Siemens, Volvo CE, plus BNP Paribas and EIB. 45% director-level or above, in CSO, CPO, and CFO functions.

Room: About 450 actual attendees at the last edition (the organizer's own 2024/2025 labeling is inconsistent); 600+ is the 2026 target. A '174 registered' counter seen live was a JS count-up animation caught mid-count, not a real tally.

Worth knowing: Wednesday Oct 7 is a separate co-located Energy Grid Intelligence Summit on its own ticket, and Monday Oct 5 evening is an invite-only CSO/CPO/CFO Leaders Club (80 attendees) that explicitly bars sellers from delegate entry. AI-matched 1:1 platform and a full attendee list go live about 1-2 weeks pre-event.

Tickets: Signatory asset owners 1,810 dollars; signatory managers and service providers 2,305 dollars; non-signatory 3,040 dollars, all plus 21% Dutch VAT. On-demand recordings 350/399 dollars, content only, no prospecting value. Early bird expired May 31; refunds until Sep 15, transfers until Oct 6; capped at 7 attendees per organisation.

Who's there: Institutional investors: asset owners and managers, CIOs, stewardship and RI heads, plus regulators. Buyers for anything sold to investors (ESG data, analytics, reporting, SFDR 2.0/Omnibus advisory). Corporates appear only as engagement counterparties, not purchasers.

Room: 1,500+ target for the 20th anniversary edition (forward marketing); the 2025 Sao Paulo actual was about 1,200.

Worth knowing: Day 0, Mon Oct 12, is an asset-owner-only forum, and Thu Oct 15 is a new 'Collaboration Day' of side events mostly needing separate registration. Matchmaking is an opt-in 'Meet your peers' directory plus 1:1 booking opening about a week pre-event; speaking submissions closed after 400+ entries.

Tickets: 2-day private-company rate ZAR 14,090 (about 940 dollars); public/NGO ZAR 10,750 (about 720 dollars); pre-conference day ZAR 6,260; digital pass ZAR 5,000 (about 350 dollars, content only). Buy 4, get the 5th free. Two unlabeled lower checkout amounts are reachable in the registration flow, so ask before paying the headline price.

Who's there: Supply-heavy, about 10% demand side by the organizer's own targets (50+ investors, buyers, and financiers of 500+). Demand is mostly capital (AfDB, UNDP, DBSA, FSD Africa, funds) rather than corporate offtake; GenZero's CEO is the clearest large-cheque buyer on the roster. Senior African policy density is unmatched: ministers, REMA, Kenya's climate envoy, DG CLIMA, IETA, and Verra.

Room: 330+ actual at the 2025 inaugural summit in Johannesburg; 500+ target for 2026. The published '77 speakers' figure mirrors the 2025 actual, so treat it skeptically.

Worth knowing: The strongest matchmaking machinery in this guide relative to size: closed-door Investor and Buyer Roundtables both mornings, two Deal Rooms for screened projects, speed dating twice, and six staggered Solution Labs. No expo floor and no self-serve app; venue is Kigali Convention Centre.

Tickets: Standard £1,495 + VAT. Super Early Bird £1,346 + VAT (10% off, no published expiry). No day pass and no virtual tier. Including VAT, that is roughly £1,794 standard or £1,615 early bird. A limited number of complimentary passes go to mid-size and large companies that buy and retire voluntary credits, excluding energy, financial, and consulting firms.

Who's there: Compliance market and finance heavy, mixed with VCM and project developers. A past-attendee list naming BP, Shell, Goldman Sachs, Morgan Stanley, and Bank of America could not be verified on current live pages. Confirmed 2026 speakers include the European Commission, IETA, the Polish climate ministry, and Vitol.

Room: Over 600 attendees in 2025 (organizer claim, unaudited). Do not cite the homepage's portfolio-wide '1,500+' figure or an unreproducible '500' figure.

Worth knowing: Moved to a new venue (Convene Sancroft, Paternoster Square) versus 2025. Third-party listings showing Oct 13-15 carry stale copy from the three-day 2025 edition; no official Oct 13 programming exists.

Tickets: Attendee rates were not verifiable on official pages as of late August 2026; a circulating figure of $30 priority through Sept 25 rising to $130 standard is unconfirmed, so check the registration page directly before budgeting. Booth pricing is not published.

Who's there: PMMI projects 48,000 attendees and 2,600 exhibitors from more than 40 vertical markets for the 2026 edition. These are organizer projections for this show rather than audited past-edition actuals, and no seniority or job-title breakdown is published. The floor mix skews toward equipment and materials buyers such as packaging engineers, plant operations staff, and procurement rather than corporate sustainability or ESG teams specifically, though PMMI's 2026 research claims more than 82 percent of end users are actively engaged in sustainability adoption.

Room: PMMI projects roughly 48,000 attendees and about 2,600 exhibitors across 40-plus vertical markets for the 2026 show. PMMI's own announcement presents these as projections for this edition rather than confirmed actuals from the last one, so treat them as a directional organizer forecast.

Worth knowing: Runs biennially. The sustainability venues to work: Sustainability Central, the Reusable Packaging Pavilion and Learning Center, and the Sustainability Solutions Finder directory of vetted PACK EXPO Green Exhibitors.

Tickets: General Pass early bird £1,795 + VAT until Sept 4. Standard price is not published, though a 'Save £200' badge implies roughly £1,995 + VAT. Startup, NGO/Gov, and Investor passes are £995 + VAT each, all application-gated. Buyer Pass price is not published, enquiry and approval only.

Who's there: Organizer-published split: 30% project development, 30% liquidity and market facilitation, 25% standards, trust, and infrastructure (MRV, registries, verifiers), and 15% demand and offtake. 75% C-suite or director level, 70% Europe-based. Sellers outnumber buyers roughly four to one by the organizer's own numbers.

Room: 400 target for 2026 (organizer projection). The site's cumulative series-wide stats (2,264 unique attendees, 1,134 companies) and a 300+ figure from the 2023 inaugural edition are not this event's actual attendance.

Worth knowing: Same two days as Reuters Sustainability Europe, also in London (Oct 20-21). Pick by audience: CDR transaction room versus enterprise sustainability strategy room. The Oct 19 Buyers' Workshop (Chatham House Sancroft venue details unconfirmed) is hosted by NEP and facilitated by a leading CDR buyer; a General Pass does not grant access, entry is via an open register-interest form and organizer approval.

Tickets: Corporates £1,999 by Sept 18 (save £200), then £2,199. Solution Providers £3,749 by Sept 18 (save £250), then £3,999. Group rates: corporate 5+ passes £1,499 each, solution provider 5+ passes £2,811 each. All prices exclude VAT. Vendors pay 80-90% more than corporates, by design.

Who's there: 400 attendees, 75% corporate sustainability executives, 60% C-suite, 66% returning. The 2026 attendee list already shows Mars, GSK, L'Oréal, Danone, Diageo, and Deutsche Bank.

Room: 400 (flat, organizer's own stat band), down from 500+ marketed in 2025.

Worth knowing: Same two days as Carbon Unbound Europe, also in London (Oct 20-21). Venue was not yet published as of Aug 19, 2026; ignore stale Hilton or Convene references left over from 2025. The event describes itself as 'built for intimacy and impact, with limited sponsorship slots and exhibition.' The 'strictly limited vendor presence' phrasing belongs to Responsible Business USA, a different Reuters event, not this one.

Tickets: Exhibition pass free, registration required. Conference pass, all tracks: 1,835 euros early bird until Sep 11, 1,985 euros standard (VAT unstated, assume plus 19%). Group discounts of 10/15/20% at 2/3/4-plus registrants.

Who's there: Engineering and supply-side. Buyers are industrial emitters and EPCs procuring capture equipment, transport, and storage, not credits or ESG software. Sustainability and ESG titles are a thin minority.

Room: 946 exhibitors and 18,684 visits in 2025 (visits, not unique people; unique attendance plausibly 9,000-13,000). The 2026 '20,000+ attendees' figure is an organizer target; the number that matters is about 1,500 conference delegates.

Worth knowing: The site was folded under the co-located hydrogen show (carboncapture-expo.com 301-redirects to hydrogen-worldexpo.com/carbon-capture-world); a rebrand, not a cancellation. CCUS-specific content is about 1-1.5 days once hydrogen tracks are subtracted. The networking app with 1:1 booking is included with the free expo pass; there is no hosted-buyer program.

Tickets: Advance rates through Oct 18, late rates unpublished: conference pass 1,399 dollars USGBC member / 1,599 dollars non-member; expo plus evening events 599 dollars; expo hall 169 dollars member, 525 dollars for non-exhibiting suppliers. Groups of 5-9 save 10%. Early bird ended Aug 7, saving 150-170 dollars per an archived table.

Who's there: Architects, contractors, engineers, building owners, and property managers; 79% work on building projects. The attending-company consultant block (Stok, Verdani, Brightworks, RE Tech, WAP) is competitors, not buyers. Real buyers (owners, REITs, asset managers, lenders) concentrate in the gated Finance Forum.

Room: '10,000+' is an unlabeled brand claim; trade press put LA 2025 at about 15,000 (unverified, the organizer site 403s fetchers). A low-five-figure room, with a much smaller reachable subset given only 2 expo days.

Worth knowing: The expo hall runs Wednesday-Thursday only, about 15 hours total, and Friday is a half-day and commercially dead. The co-located Sustainable Finance & Investing Forum runs Oct 20-21, application-gated, roughly 499 dollars in 2025 with 2026 pricing unpublished.

Tickets: Four ticket tiers, all plus UK VAT (non-UK businesses may be able to reclaim it): Biofuels Ticket GBP 2,399; Biofuels & Networking Ticket GBP 3,098 (adds exhibition-hall access on 20 Oct); Biofuels & Marine Ticket GBP 3,498 (adds Marine Focus Day); Biofuels & SAF Ticket GBP 3,598 (adds SAF Focus Day). Group discounts run 15% off 3 passes, 20% off 5, and 25% off 8, same-ticket-type bookings only, and mixed-ticket groups have to contact sales. Payment is by credit card at online registration, and the registration page publishes no early-bird deadline.

Who's there: The organizer publishes 600+ attendees and 300+ companies represented from over 50 countries, with 30 percent of the audience at C-suite or director level. Confirmed 2026 attendees named on the site include American Airlines, Carnival Corporation, Cathay Pacific, CMA CGM, Daimler Truck, DHL Express, ENI, Essar Oil, FedEx, Finnair, Hapag-Lloyd, IATA, International Airlines Group, JetBlue, Kuwait Petroleum, Mitsubishi Corporation, Mitsui O.S.K. Lines, Moeve, Petrobras, Repsol, RSB, Scania, Shell, Stena, Verbio, Vitol Group, the European Commission and the UK Department for Transport. That list mixes fuel buyers (airlines, shipping lines), fuel producers and traders, and policy bodies.

Room: Organizer publishes 600+ attendees and 300+ companies from over 50 countries, with 30 percent of the room at C-suite or director level. The 2025 edition generated 1,155 meeting requests and 911 connections on the official networking platform. You can download a sample delegate list from the event page.

Worth knowing: The SAF Focus Day and Marine Focus Day are optional add-on tracks held 20 October, the day before the main two-day conference (21-22 October). Both need a higher-tier ticket rather than the base Biofuels Ticket. The base ticket still includes welcome drinks on 20 October but no exhibition-hall access that day.

Tickets: Visitor registration is free. The official visitor registration form collects name, company and contact details with no payment step. Exhibitor stand pricing is not published on the pages reviewed, though the site links a 2026 sales brochure PDF for prospective exhibitors.

Who's there: The 27th edition (2025) drew around 3,100 exhibiting companies from 65 countries, 68 sponsors, 18 international country pavilions and 50,000+ total visitors across 114 specialized sessions and 95,000 square meters. The organizer pitches access to 'government decision-makers, business leaders, investors and country delegations.' No seniority percentage breakdown or 2026-specific attendee count is published.

Room: The 2025 (27th) edition reported 50,000+ total visitors and about 3,100 exhibiting companies from 65 countries (organizer-reported actual). Figures for 2026 are not published yet, since the event has not occurred.

Worth knowing: Dates overlap exactly with Argus Biofuels Europe (also 20-22 October 2026, London). The two serve different buyer bases: Gulf utilities and government on one side, the European biofuels value chain on the other.

Tickets: Registration pricing is not published on the official event page or on its Swoogo registration site (acore.swoogo.com/GridForum2026); both link straight to a Register Now action without any visible fee table. Exact cost, any member versus non-member split, early-bird deadline, and tax status are not disclosed publicly and must be obtained from ACORE directly.

Who's there: The official event page states more than 60 percent of attendees hold C-suite, VP, or Director-level titles and puts total attendance at 150-plus people from clean energy companies, spanning corporate off-takers, developers, financial institutions, investors, and utilities. It names Amazon, Bank of America, Berkshire Hathaway Energy, Goldman Sachs, Google, J.P. Morgan, Meta, NextEra Energy, Walmart, and Wells Fargo among 20-plus organizations, though these are listed as part of the forum's executive council or sponsor group rather than a confirmed attendee roster.

Room: The official page states 150-plus attendees with more than 60 percent at C-suite, VP, or Director level, across 5 panels and 30-plus speakers. The page does not clarify whether the attendance figure reflects a past edition or is a projection for the October 2026 date, so it should be read as an organizer figure rather than a verified actual.

Worth knowing: Date, single-day format, and the 150-plus / 60-percent-senior stats are confirmed on official ACORE pages. Venue is Convene Hamilton Square, 600 14th Street NW, Washington, D.C. 20005, disclosed only on the Swoogo registration page. No public pricing exists on either official page, so contact ACORE directly to confirm cost and any discount before budgeting a sponsorship.

Tickets: Delegate fees for SIEW Summit passes are not published on the public event site, and registration runs through a separate portal at register.siew.gov.sg. Treat pricing as on request and check that portal directly for current rates. Pricing for the co-located Asia Clean Energy Summit is published separately and listed under that event's own entry.

Who's there: The official 2026 factsheet describes the SIEW Summit as gathering high-level speakers from government, industry and international organisations, and the program it publishes includes a Singapore-IEA Forum, a Singapore-IRENA High-Level Forum, the inaugural IAEA@SIEW forum and an ASEAN Energy Regulatory Forum. That structure points to a senior mix of ministers, regulators, utility C-suite and multilateral agency leaders. Individual 2026 speakers are not named in the factsheet, and no buyer-to-seller ratio is published.

Room: The official 2026 factsheet states that in 2025, SIEW attracted more than 23,000 onsite attendees from over 70 countries. This is an organizer-reported actual for the prior (2025) edition, not a confirmed 2026 attendance figure or target.

Worth knowing: Asia Clean Energy Summit, Asia Gas Markets Conference, Future of the Grid and other partner events run inside SIEW week at the same Marina Bay Sands venue on overlapping days, so one trip can cover several of them, but each partner event sells its own registration at its own price and has to be booked separately.

Tickets: Exact registration tiers are not published on the official event page; the only disclosed figure is 'save up to $800 with Early Bird Pricing,' with no stated early-bird deadline or standard price visible without entering the registration flow. Group rates are available for 3 or more attendees via [email protected], and a separate Government, Academic & Non-Profit registration category exists though its rates are also unpublished. Complimentary passes are offered only to qualifying Data Center Developers, Owners/Operators, Corporate Tenants, and Hyperscalers, with Powered Land and Energy Campus developers explicitly excluded; a maximum of one pass per organization, first-come first-served, subject to Infocast review. All other attendee types, including most sellers in our niches, pay an undisclosed standard fee.

Who's there: The official event page lists more than 50 named organizations across three groups without stating an overall attendee count or seniority split: project developers and operators including Aligned Data Centers, Capstone DC, DC Blox, Soluna, The AES Corporation, and TotalEnergies; capital sources including Bank of America, Barings, BlackRock, I Squared Capital, Macquarie, Nuveen, and Partners Group; and service providers including Black & Veatch, JLL, Moelis, and White & Case. The page also carries a testimonial referencing a July 2026 PowerUp Data Centers event, and Infocast runs a separate PowerUp Data Centers edition on July 20-22, 2027, so the named-company list may reflect the series generally rather than a confirmed roster for this exact October date.

Room: The official page cites 95 expert speakers and 16 sessions over three days but does not publish a total attendee count for this edition; the 50-plus named companies are a sponsor/participant list rather than a verified headcount.

Worth knowing: Dates, venue, 95 speakers, 16 sessions, the $800 early-bird claim, the $249/Oct 5 hotel cutoff, and the comp-pass rules are all confirmed on official Infocast pages. Exact ticket pricing sits behind the registration flow and is not visible on any public page; budget for a standard-rate paid pass unless your company qualifies for a complimentary developer/operator/hyperscaler pass, and note that Powered Land and Energy Campus developers are specifically excluded from that comp tier. Registration contact: [email protected] or (818) 888-4444. This event runs Oct 27-29, close on the calendar to ACORE Grid Forum (Oct 22) and PACK EXPO International (Oct 18-21), all in the same late-October window.

Tickets: The official 2026 registration page lists four pass tiers in Singapore dollars: ACES SMNP at SGD 1,800, ACES NM at SGD 2,200, an IRENA pass at SGD 1,300, and a Complimentary Pass at SGD 0. Both paid full-access tiers cover the day 1 opening ceremony and Clean Energy Leaders' Dialogue, the Singapore-IRENA High-Level Forum, the day 2 Solar and Storage, Energy Efficiency and Sustainable Fuels tracks, day 3 access to other partner events, day 1 and 2 exhibition entry, networking sessions, ACES Meet and Match, and F&B. The SGD 1,300 IRENA pass covers the Singapore-IRENA High-Level Forum plus exhibition entry, networking sessions, Meet and Match and F&B, while the free pass covers exhibition entry and Meet and Match only. The page does not state whether prices include Singapore GST, and no early-bird deadline is listed.

Who's there: The official site describes ACES as supported by leading government agencies, research institutes and industry in Singapore, and as a common platform for regional thought leaders in both the public and private sector. It is organised by SEAS and runs as part of SIEW. The site does not publish a seniority percentage, a buyer-to-seller ratio, or a named attendee list beyond its sponsors and partners.

Room: No attendance figure or target specific to ACES is published; it runs as one of several co-located tracks inside SIEW week, which drew over 23,000 total onsite attendees in 2025 across all combined SIEW programming (an organizer-reported prior-year actual, not an ACES-only count).

Worth knowing: ACES runs inside SIEW week at Marina Bay Sands alongside the SIEW Summit and other partner conferences, so hotel and travel demand across the whole week is high; book venue accommodation early. Its own tracks run on days 1 and 2, with day 3 giving pass holders access to other SIEW partner events.

Tickets: General visitor admission is complimentary if registered before 13 October 2026, rising to 60 AUD excluding GST (Australia's VAT) after that date; this appears to cover both the expo floor and the 100-plus conference sessions, since no separate paid conference-only tier is listed. A Two-Day VIP Upgrade costs 280 AUD excluding GST and adds dedicated badge collection, catering vouchers, and early access to the organizer's on-demand education hub. Exhibitors register separately through an exhibitor portal, not the visitor form.

Who's there: The 2025 edition drew 16,012 AMAA-audited unique visitors (marketed as 16,500-plus) from more than 60 countries, plus 490-plus exhibiting suppliers, and the organizer reports 29 percent of attendees held purchasing authority over 2 million AUD. The 2026 program lists 500-plus speakers across 100-plus sessions and 10-plus workshops and stages, with named platinum sponsors including Sungrow, FoxESS, GoodWe, Hithium and NEXTracker. Specific attendee job-title or seniority breakdowns beyond the purchasing-authority stat are not published.

Room: 2025 actual attendance (AMAA-audited) was 16,012 unique visitors and 490-plus exhibitors. The organizer's 2026 marketing anticipates a similar 490-plus exhibitor count, but no independently verified 2026 attendance figure exists yet since the event has not occurred.

Worth knowing: Co-located at the same venue and on the same dates as Waste Expo Australia and its Greener Infrastructure Conference, so one trip can cover both renewables and circularity buyers, though the two events register attendees separately and no shared-badge policy is published on either site.

Tickets: The exhibition show floor itself is free to attend for trade visitors. The separately ticketed Greener Infrastructure Conference costs 850 AUD excluding GST (Australia's VAT) for a two-day all-access pass at the standard rate, which applies from 28 August 2026; an early-bird rate cuts 200 AUD off that price, to 650 AUD excluding GST, for registrations received up to and including 27 August 2026. Group discounts of 5 percent for 5-plus delegates and 10 percent for 10-plus stack with early-bird pricing. The pass includes two days of sessions, meals, a day-one networking reception, and access to the co-located exhibition.

Who's there: The organizer's 2026 projection is 3,500-plus industry connections, 140-plus exhibitors, and 110-plus speakers across three conference stages; these are stated targets, not audited actuals, since no verified prior-year attendance figures were found on the official site. The organizer describes attendees as local, state and federal government officials, waste service providers, consultants, engineers, technology and equipment suppliers, project developers, facility managers, landfill owners and operators, and NGOs, spanning both public and private sectors; general public entry is excluded.

Room: Organizer-stated 2026 target is 3,500-plus attendees and 140-plus exhibitors. No independently audited actual attendance figure for this or a prior edition was found on the official event site, so these numbers should be read as the organizer's projection rather than a verified result.

Worth knowing: The Greener Infrastructure Conference's early-bird rate applies through 27 August 2026; the standard 850 AUD rate takes effect from 28 August 2026. The show floor itself stays free regardless. Co-located with All-Energy Australia at the same venue and on the same dates.

Tickets: All-access delegate 7,250 dollars (early bird 7,171.50 dollars expired Apr 30); technical pass 2,030 dollars (VAT treatment unstated, assume plus 5%). The 2026 visitor pass is unpublished; the prior edition was 50 dollars advance / 100 dollars on-site. An all-in trip realistically runs 12,000-15,000 dollars.

Who's there: NOCs and majors (ADNOC, Aramco plus 54 NOC/IOCs), 45 ministers, EPCs, traders, and finance. The Clean Power, Molecules & Carbon Management programme targets offtakers and traders within a carbon-capture framing. Low Carbon Zone exhibitors are industrial hardware makers such as Topsoe, Rittal, and Weidmuller.

Room: '239,000+' is unlabeled organizer marketing; press reported 218,329 for the 2025 close. The number that matters is 16,500 conference delegates. Deal-value claims conflict internally (53 vs 46 billion dollars for the same edition), so neither figure is quotable.

Worth knowing: A real 4 days across 16 halls and 13 conference programs (380+ sessions); the per-program day split is unpublished, so a compressed trip can't be planned yet. There is no hosted-buyer program; country pavilions run their own B2B programs via national trade bodies, often the cheapest quality path in.

Tickets: Visitor pass 200 euros (was 175 euros super early bird, expired Jun 30; VAT included). Full Congress 1,250 euros; Investor 1,495 euros, built for VC-startup matching, not sales. Extra 10% off via email signup; group discount 25% at 6-plus. Government pass is free, which is why buyer density holds.

Who's there: Municipal: mayors, city sustainability and resilience officers, urban planners, and utility and transit leads, attending in delegations for free. 55% decision-makers, 27% government titles. Corporate CSOs and CSRD buyers are absent.

Room: 2025 actual: 27,000+ attendees, 143 countries, 1,190 exhibitors (Microsoft, Google, Nvidia, Dell), about 350 startups. 2026 projects the same.

Worth knowing: Six co-located congresses share the venue and the headline attendance figure. The Smart City Open Innovation Challenge publishes cities' actual procurement problem statements and pre-schedules B2B meetings, the best free way in.

Tickets: Tickets are trivially cheap: 15 euros for 1 day, 30 euros for 2 days pre-booked online, 35/45 euros on-site, though the ticket page still carries the prior edition's date windows until IEG re-dates the table around late September. The real cost is a stand: no official rate card, but national-pavilion benchmarks run about 350-500 euros per square meter all-in. Hosted buyers attend free with accommodation support.

Who's there: Waste and recycling operators, water utilities, municipalities, industrial groups, and equipment makers. Italian and Euro-Mediterranean, about 9-10% international skewing Iberia, the Balkans, Turkey, and North Africa. Buyers buy plant and machinery, not offsets or reporting suites.

Room: 'Over 108,800 participants' is cited for 'the last edition' with no year attributed (the 2024 attribution can no longer be re-verified; its press release 404s). 'Participants' counts attendance events including exhibitor staff and students. 1,700+ exhibiting brands and 800+ hosted buyers from 65 countries per the 2025 release.

Worth knowing: 29th edition, Tuesday-Friday, 4 real days; Friday is the light and student day. Conference content is largely in Italian, with about 1.5-2 days' worth in English. Matchmaking (the 'My Agenda' platform and the International Buyer Program) is exhibitor-to-buyer only; a walk-in visitor gets the catalogue.

Tickets: Fees are quoted in EUR. Sellers ("Suppliers & Others") pay EUR 1,155 excl. VAT with a WindEurope, SolarPower Europe, or WBCSD membership, or EUR 1,620 excl. VAT without one; 21% Dutch VAT applies at checkout. Renewable energy buyers, government officials, press, and speakers register free. No early-bird deadline is listed on the registration page.

Who's there: Organizer figures put the event at 1,400+ participants, including 350+ corporate energy buyers and 140+ speakers. Attendee testimonials on the official site name buyer-side representatives from Google, Coca-Cola European Partners, Umicore, ROCKWOOL, and Metlen. A buyers-only day (Nov 3) precedes the main two-day conference (Nov 4-5).

Room: Organizer-published figures, repeated across both the 2025 and 2026 event promotion rather than broken out as a verified count for this specific edition: 1,400+ participants, 350+ corporate energy buyers, 400+ B2B meetings, 140+ speakers.

Worth knowing: The Nov 3 buyers-only day is reserved for corporate energy buyer delegates; sellers attend the main Nov 4-5 conference. Venue is Beurs van Berlage, Damrak 243, Amsterdam.

Tickets: 3-Day Pass $2,799 (struck-through $3,299). 2-Day Pass $2,299 (struck-through $2,799). Group 3-for-2 rate: $5,598 for three 3-day passes or $4,598 for three 2-day passes. Airline representatives attend free. No published early-bird cutoff; prices are point-in-time.

Who's there: 800 senior decision-makers (organizer projection for 2026, not a verified 2025 actual), spanning airlines, fuel producers, financiers, and policymakers. Airline representatives attend free.

Room: 800 senior decision-makers, an organizer projection for 2026; no audited attendance figure has been published for any prior edition.

Worth knowing: The only event on this list that contractually guarantees meetings: 25 with a 3-day pass, 10 with a 2-day pass. Day 1 is a masterclass and networking day; the main conference runs Nov 5-6. Do not cite inspenet.com, which carries wrong June dates.

Tickets: Free, registration required and data-gated. Replays are free on YouTube, so live attendance mainly buys a seat in a small, capacity-capped breakout room.

Who's there: Founders and investors, skewed toward venture deal flow rather than corporate buyers. SOSV's own matchmaking eligibility rules state, verbatim, 'Service providers, this event is not for you.'

Room: About 6,000 participants for the 2025 edition per SOSV's own recap; the '10,000 each time' claim in the announcement contradicts that figure, and the homepage's '5K attendees' badges are retrospective. The Nov 4 climate audience will be a slice of that.

Worth knowing: Formerly the Climate Tech Summit; rebranded to Deep Tech Summit with climate content cut from a full week to one day (Nov 4; Nov 5 is human health, Nov 6 is physical AI). The canonical site is sosvdeeptech.com; sosvclimatetech.com still serves stale 2025 pages. The VC-Founder Matchup (Nov 16-20) explicitly excludes service providers, and the climate-specific matchup runs in September, ahead of the November summit.

Tickets: All USD, no sales tax at checkout, all tiers labeled Early Bird as of Aug 25, 2026. General rates: Full Access Pass $2,990 (3 days), Main Summit Pass $1,895 (2 days, Nov 5-6), Executive Briefing Pass $1,095 (Nov 4 only). Discounted Government, End User, and Non-Profit rates ($2,190 / $1,395 / $795, subject to Infocast verification) close Sept 11 at 23:59 ET, the only hard deadline published. The advertised 'save up to $900' has no published standard price behind it, so the saving cannot be verified. Group rates at 3+, amount unpublished.

Who's there: Organizers describe the buyer/seller mix as utilities, municipal utilities, consultants, developers, regulators, equipment providers, generation and transmission cooperatives, corporate energy buyers, EPCs, co-ops, attorneys, and vendors. Confirmed 2026 speakers include state regulators (North Carolina Public Staff, Georgia Public Service Commission, South Carolina Office of Regulatory Staff, Mississippi Public Service Commission, Kentucky Public Service Commission), utilities (Duke Energy, Dominion Energy, Southern Company, Entergy, Santee Cooper), developers (EDP, Silicon Ranch, TerraForm Power, Cypress Creek Renewables, Origis Energy, Invenergy), a corporate buyer (Google) and the Clean Energy Buyers Association (CEBA). A visual-only attendee demographics chart is posted on the event page but no numeric seniority breakdown is published.

Room: 2025 edition (held under the prior name Southeast Renewable Energy, organizer-reported actual): 325+ participants, 78 speakers, 20 sessions. 2026 edition (rebranded Southeast Power NEXT, organizer target/marketing copy): approximately 500 attendees, 95 confirmed speakers, 20 sessions.

Worth knowing: Renamed from 'Southeast Renewable Energy' for 2026 with a broader power-market scope; organizers say it serves the same core community. Hotel block at the Sheraton Charlotte is $249/night with an Oct 13 cutoff. The 2027 edition is already scheduled for Oct 13-15, 2027 in Charlotte.

Tickets: Physical tickets cost HKD 1,200 and virtual attendance is free, per the official registration page. The page does not state whether the physical price includes Hong Kong tax, and no early-bird tier or discount deadline is listed.

Who's there: The official page lists this edition's partners as UN Environment Programme Finance Initiative as co-organizer, BDO Unibank as strategic partner, and the Asia Investor Group on Climate Change, the International Capital Market Association, CDP and ReThink HK as knowledge partners. That mix points to a senior room of bank sustainable-finance heads, asset managers, regulators and corporate sustainability leaders. The speaker lineup and agenda for the Hong Kong 2026 edition are not yet published, and the organizer does not publish a seniority percentage or a buyer-to-seller ratio for this edition.

Room: The organizer has not published an attendance figure or target for the Hong Kong 2026 edition itself. The page mentions that ReThink HK, a separate co-organized Hong Kong sustainability expo, drew over 8,000 in-person attendees at its 2024 edition, but that is a different multi-day conference and not a count for this one-day forum.

Worth knowing: This is a single-day, boardroom-style forum focused on capital and policy discussion, so expect panel and networking formats rather than an exhibition floor with vendor booths. It takes place at the Hopewell Hotel in Hong Kong.

Tickets: Blue Zone badge is free but requires nomination through an accredited observer organization such as IETA, and is not purchasable; many side-event and partnership application tracks closed Aug 14, 2026. IETA Business Pavilion (Blue Zone) registration is free for duly nominated participants; speaking and branding slots are paid partnerships, price on request. Green Zone registration is 'coming soon' with no price published. Startup Zone desk stands (companies 0-3 years), 5 sqm booths, and 15 sqm booths are priced on application; applying is an expression of interest, not a reserved space. The World Climate Summit or Investment COP Antalya edition is confirmed in intent only, with no dates, venue, or pricing published.

Who's there: Large corporates, development-finance institutions, delegations, NGOs, and lobbyists dominate the room. Mid-market corporate buyers are statistically the rarest species at a COP.

Room: Roughly 100,000 projected across both zones (organizer projection). COP29 Baku drew about 70,000 badges.

Worth knowing: Pre-COP runs Oct 5-8 in Fiji; World Leaders' Summit is Nov 11-12. Antalya accommodation is already tightening and pricing above normal November levels. The Startup Zone (3,600 sqm inside the Green Zone) is billed by organizers as the first at this scale at any COP.

Tickets: General 630 euros (775 euros including Portuguese tax; 'limited stock', rolling increases, no dated tiers). VIP 1,585 euros adds bookable meeting rooms, the tier that matters for scheduled meetings. Groups from 567 euros per ticket at 5-plus. Investor passes are free by application or a paid 1,950-euro Platinum tier.

Who's there: Founders, investors, media, and government delegations; no corporate-buyer segment exists. KPMG, PwC, and Salesforce attend as exhibitors, meaning competitors bought the booths, not clients.

Room: 71,386 attendees in 2025, an organizer post-event actual; 1,857 investors, a record, 2,725 startups, and 1,519 media. No per-track figures exist; assume the climate slice is a low single-digit percentage of 71k.

Worth knowing: The Planet:Tech sustainability track is gone from the 2026 Lisbon lineup; its URL now serves the Energy Summit (AI power demand, energy security, hydrogen and storage, SMR, fusion, grids), with only one Energy session published so far. Nov 9 is opening night only, based on the prior-edition pattern and not yet 2026-confirmed.

Tickets: Three pricing windows, each with Standard and Package tiers (Package adds a Gala Dinner ticket at a 20% saving). Early bird, to 24 Apr 2026: CIWM/ISWA members GBP 597.60/751.60, non-members GBP 747/901, students GBP 224.10/378.10, low-income-country attendees (World Bank classification) GBP 373.50/527.50. Standard, to 1 Oct 2026: members GBP 664/818, non-members GBP 830/984, students GBP 249/403, low-income-country attendees GBP 415/569, speakers GBP 464.80/618.80 (members) or GBP 581/735 (non-members). Last chance, to 9 Nov 2026: members GBP 863.20/1,017.20 and non-members GBP 1,079/1,233 only. All prices add 20% UK VAT at checkout. A standalone Gala Dinner ticket is GBP 192.50, or GBP 1,925 for a table of 10.

Who's there: CIWM projects about 1,200 delegates from more than 50 countries for 2026. That is an organizer estimate, reported when early-bird registration opened (via Waste Management World, Feb 2026); the congress has not happened yet, and there is no prior UK-hosted edition to benchmark against. Organizer copy describes the room as practitioners, policymakers, researchers, and academics across five program themes: human rights, political commitment, waste planning, the economics of waste and resource management, and circular economy. No exhibitor or delegate company list has been published.

Room: Organizer projection only, since the congress has not occurred. CIWM anticipates about 1,200 delegates from more than 50 countries, per its registration-opening announcement covered by Waste Management World (Feb 2026). No verified attendance figure exists yet, and as the first UK-hosted edition in three decades it has no comparable prior-year UK number.

Worth knowing: The early-bird window closed on 24 Apr 2026, so standard pricing runs through 1 Oct 2026 and last-chance pricing applies from then to the event. Student, low-income-country, and speaker rates sell only in the early-bird and standard windows, so anyone in those categories should book before 1 Oct 2026. The Gala Dinner is on Tuesday 10 Nov. Site visit and technical tour tickets had not gone on sale as of late Aug 2026.

Tickets: A free Expo pass is available, and the official event page promotes a saving of up to 500 euros on the Summit for registrations made by 20 September 2026. The resulting discounted Summit price is not broken out on that page, and no VAT statement appears there. Summit Pass list pricing and any group or student rates are published on the official registration page, so confirm the current figures and VAT treatment there before budgeting.

Who's there: The organizer's own event page states 15,000 expected attendees, 750 exhibitors, 600 speakers, 140 countries represented and 160 side events for the 2026 edition, framed on the page as expectations rather than a confirmed post-show count since the event has not yet taken place. No published breakdown of attendee seniority or buyer-to-seller ratio was found on the official site.

Room: Organizer figures published on the event site for the 2026 Vienna edition state 15,000 expected attendees, 750 exhibitors, 600 speakers, 140 countries represented and 160 side events. These are pre-event organizer projections, not a verified post-show actual, since Enlit Europe 2026 has not yet occurred.

Worth knowing: Enlit Europe now sits on the enlit.world domain, and the older enlit-europe.com address redirects there, so update any saved bookmarks. The promoted Summit saving carries a 20 September 2026 deadline, so sellers planning to buy Summit access should register well ahead of the show.

Tickets: Early bird through Sep 10, later rates unpublished: full conference 1,097 dollars member / 1,387 dollars non-member. Expo-only 295/395 dollars, one-day 165/225 dollars. Executive Program add-on 300/500 dollars, VP-plus only. Refunds end entirely Oct 2.

Who's there: 40% executive level, EPC 20%, manufacturer 13%, consultant 9%, developer 9%, IPP 7%, 83% US, from a 37,000-person 2025 actual.

Room: 37,000 attendees, 1,300+ exhibitors (2025 actual, from the organizer's post-show report).

Worth knowing: RE+ left its September slot; 2026-2028 run in November at the Las Vegas Convention Center. Education day Mon Nov 16 has the expo closed, full days are Tue-Wed, and Thursday fades as F1 Vegas GP weekend opens (the race is Sat Nov 21). RE+ publishes a zero-tolerance suitcasing policy naming non-exhibiting attendees who sell, enforced beyond the hall into hotels and restaurants; the compliant route is pre-booked meetings via the Swapcard-based RE+ Connect app.

Tickets: Startup 395 euros, application-gated, founded 2016 or later; Investor 1,195 euros; Ecosystem 1,195 euros, the tier corporates, consultants, and service providers need, was sold out as of Aug 19. Thursday pass 595 euros, approval-gated, is the only remaining route for a non-startup. All prices include 13.5% Finnish VAT.

Who's there: Founders and VCs (a16z, Sequoia, Index, Accel, Creandum named), partner and CEO seniority, European-weighted. Corporate sustainability and procurement budgets are effectively absent.

Room: 12,000+ target, with '76% startups or investors' framed as a projection about a future event. No audited actuals exist; about 13,000 is the historic organizer figure. Ignore '20,000+' aggregator claims, which conflate Slush Week.

Worth knowing: Day 0, Nov 17, is founder-social programming. The Climate Summit side event is not confirmed for 2026; the live climate page is a stale 2025 artifact, and side-event applications open fall 2026. The Slush Platform offers an open directory of all registered attendees plus 25-minute meeting booking, but there are no vendor booths for established providers.

Tickets: Day 2 ESG Summit 880 euros / 620 euros early bird; Day 1 or Day 3 480/320 euros; 2-day 1,156/799 euros; 3-day 1,564/1,071 euros, all including 19% VAT. No early-bird cutoff is published anywhere; the 29-33% discount argues for buying rather than waiting.

Who's there: The draw is the award ecosystem. The ESG Transparency Award recognized 50+ European companies in 2025, which pulls pre-qualified heads of sustainability and ESG reporting into the room. Speakers include UBA president Dirk Messner and Michael Braungart; 2025 had Robert Habeck and Deutsche Telekom. Sponsors SAP, Arvato, DNV, and TUV Rheinland are simultaneously validation and competition. Day 1 skews solar-supplier-to-supplier.

Room: 500+ across all three days (2025 organizer actual); any single day is smaller. The room is small, dense, and DACH-centric.

Worth knowing: Venue is the Steigenberger Grandhotel Petersberg in Königswinter, near Bonn. Three distinct forums: Day 1 Environmental Forum (energy, English), Day 2 ESG Summit (the anchor, English, running into an evening gala), Day 3 Social Forum (half day, German only). Delegate list access is a sponsor benefit, not a ticket benefit.

Tickets: All tiers in USD, excluding VAT. Super Early Bird (by Sept 25): conference $1,599, conference plus training $2,994, training only $1,395. Early Bird (by Oct 30): $1,799 / $3,394 / $1,595. Standard (by Nov 27, when registration closes): $1,999 / $3,798 / $1,799. Group rate: buy 3, get 1 free. S&P's own Overview copy wrongly states the super early bird has expired; the Pricing tab is authoritative.

Who's there: Policymakers, corporates, project developers, financiers, and traders. Registration includes a networking app with the delegate list and in-app meeting requests, though no curated matchmaking program is advertised. A 2025 attendee recap from a project developer described the value as meeting fellow developers and rating agencies rather than buyers, so the room leans supply-side.

Room: No official per-edition count. A third-party count (Net Zero Compare) reported over 200 for 2025. S&P's '400+ attendees from 40+ countries' is a cumulative across-years figure, not a single-edition count.

Worth knowing: Room block 250 euros/night, cutoff Oct 30. Shares the same city and week as the IEA-IETA-EPRI Workshop (Dec 1-3); the two programs run concurrently on Dec 1-2 (workshop Day 1 starts 13:30), so one Paris trip covers both but means splitting days between them, not stacking them. DeCarbon Tokyo runs the same week on the other side of the world. Cite only the spglobal.com/energy canonical URL; legacy energy.spglobal.com and commodityinsights.spglobal.com URLs serve stale editions.

Tickets: Free, but invitation-only, in-person only with no remote option, and under Chatham House Rule. Contact [email protected].

Who's there: Policy and compliance-market structure crowd: senior government officials, corporate executives, and researchers. Sponsors of the 2025 Dialogue included Chevron, ICE, Gold Standard, and Mercuria.

Room: Over one hundred senior government officials, corporate executives, and researchers at the 25th edition in 2025 (per IEA). IETA's 2026 page publishes no headcount.

Worth knowing: Day 1 runs from 13:30, Day 3 ends 12:30, at IEA Headquarters, 9 Rue de la Fédération, Paris. Runs concurrently with the S&P Global Carbon Markets Conference on Dec 1-2 (S&P runs Nov 30-Dec 2), so a Paris trip covering both means splitting days. The 'IETA Global Carbon Market Dialogue, Dec 4, 2026' cited in some sources is a stale-year error for the Dec 4, 2025 edition; no 2026 Dialogue has been announced, though if IETA follows the 2025 pattern it would land on the workshop's final day.

Tickets: Not published; fee on request, CMT's standard model. A 'super early bird' tier is open with no numbers shown. A group or team discount exists, amount undisclosed. Hotel block ¥47,234/night, a room rate, not a ticket price.

Who's there: Japan and APAC compliance and CDR crowd: METI, GX-ETS players, trading houses (Mitsubishi, Sumitomo), shippers (MOL, NYK procurement speakers in 2025), and CDR technology firms (Climeworks). Day 2 includes a complimentary Corporate Buyers Primer Forum on credit and removal procurement, restricted to qualified Japanese corporate buyers, speakers, and partners.

Room: 350+ senior decision-makers, organizer target for 2026. No independent count exists for any edition.

Worth knowing: 2025 was held at the Hilton Tokyo; 2026 moves to the Tokyo Marriott. The Corporate Buyers Primer Forum is closed to sellers. CMT also promotes a Corporate Buyer Access Initiative connecting GX-League emitters with solution providers, worth asking about when requesting a quote. Falls the same week as the S&P and IETA Paris events on the other side of the world.

Tickets: Service provider, the tier all three ICPs pay, 1,099.50 euros, discounted from 2,199 euros; end user 999.50 euros, discounted from 1,999 euros; group of 3-plus 799.50 euros per head, discounted from 1,599 euros, VAT unstated. Bronze sponsor at 5,500 euros, discounted from 11,000 euros, is the only published route to a speaking slot. The site-wide discount deadline has rolled from Aug 21, 2026 to Sep 25, 2026 and is still stamped identically on all seven tiers, which marks it as a rolling urgency device rather than a real cutoff.

Who's there: 13 published speakers split roughly into thirds: genuine decarbonization owners, including Aurubis's Head of Decarbonization and E.ON's Head of Decarbonisation Management & CDR, the single most relevant buyer title in this guide for a removals seller, finance and analysts (SocGen, ING, BloombergNEF), and academics. Shell's speaker is from real estate and corporate travel, not trading, and WSP is on stage as a competing consultant, not a buyer.

Room: '100+/150+ industry leaders' claims are template boilerplate repeated verbatim across Leadvent's event pages. Leadvent's own cumulative stats average about 30 attendees per event historically; plan for 60-120, a meaningful share vendors.

Worth knowing: First edition from Leadvent, with no 'Nth annual' prefix and nothing in its roughly 90-event archive, so treat all claims accordingly. The venue is now confirmed: Steigenberger Airport Hotel, Stationsplein Zuid-West 951, 1117 CE Schiphol, Amsterdam. App-based matchmaking opens about a month prior with 1:1 pre-booking.

Tickets: Visitor registration is complimentary and includes access to the full exhibition, all conference sessions, and Abu Dhabi Sustainability Week public events, per the official registration portal. The Sustainability Business Connect buyers programme, a concierge meeting-matching track for pre-vetted budget holders managing large sustainability project pipelines, also states that registration is complimentary and grants access to all conferences and the entire exhibition area. No paid ticket tier is published for the 2027 edition.

Who's there: The organizer states 51,000-plus attendees and 500-plus exhibitors. Its Sustainability Business Connect buyer programme reports 372-plus vetted buyers from 124 countries in the 2026 edition, across six categories: public-sector leaders such as ministers and municipal directors, energy decision-makers including utility CEOs and grid operators, urban planners and infrastructure consultants, corporate sustainability and ESG heads, investment professionals spanning venture capital, private equity, and green finance, and water and waste executives. The programme says it connects these buyers to sustainable projects worth over 10 billion dollars. Official pages disagree on the buyer count, with the Buyers Programme page citing 372-plus for 2026 and the About page citing 600-plus pre-qualified buyers, so treat the figure as approximate. No seniority percentage breakdown or named-company attendee list is published.

Room: The organizer's current marketing pages state 51,000-plus attendees and 500-plus exhibitors without labeling them as actuals or forecasts. The Buyers Programme page's 2026 recap block gives 455 exhibiting companies from 60 countries, so the 500-plus headline reads as forward-looking rather than a verified 2026 actual. No separate 2027 attendance target is published.

Worth knowing: WFES sits inside Abu Dhabi Sustainability Week, so the free badge also grants access to several co-located events such as the International Water Summit. Expect a packed week if you also want dedicated time in those adjacent programs.

Tickets: Registration runs through an external login-gated portal at registration.fmf.sa that renders no visible price, currency, or fee information without an account, and no pricing page exists elsewhere on the public site, so ticket cost cannot be confirmed from official sources. Sellers should register as a Forum Delegate through that portal and expect a screened or invite-weighted process typical of Saudi government-convened forums, then confirm any fee directly with organizers.

Who's there: The organizer reports 21,500 attendees, 300 C-suite executives, 450 speakers, 274 sponsors and exhibitors, and 147 conference sessions for the 2026 edition, alongside 5,075 facilitated business meetings, 132 MOUs and agreements signed, and more than 25 billion dollars in capital aligned. These are organizer-reported actuals from the most recent edition. No attendance projection specific to the January 2027 edition is published on the public site.

Room: 21,500 attendees is the organizer-reported actual for the 2026 edition. No 2027-specific attendance target is published on the site.

Worth knowing: The 2027 edition runs at the King Abdulaziz International Conference Center in Riyadh. Registration runs through a login-gated external portal rather than a public pricing page, so budget extra lead time to request access and confirm cost or invite terms directly with organizers before committing to travel.

Tickets: No pricing or registration tiers are published on the official event page as of 2026-08-25. The page states 'Stay Tuned for More Updates about 2027!' and offers only a lead-capture form (name, title, organization, email, phone) rather than a ticket-purchase flow, so exact 2027 pricing cannot be reported.

Who's there: Organizer copy describes CEOs, CFOs, chief investment officers, infrastructure fund leaders, heads of project finance, tax equity providers, IPPs, investment and commercial banks, private credit providers, law firms, insurance providers, and utilities. Named 2026 speaking organizations include BNP Paribas, Bank of America, Deutsche Bank Securities, EDP Renewables, Brookfield, Ares Management, MUFG, Nord/LB, Fifth Third Securities, CleanCapital, Lotus Infrastructure Partners, GridStor, Cypress Creek Renewables, American Clean Power, and ACORE. No numeric seniority breakdown is published.

Room: 2026 edition (organizer-reported actual, from the page's '2026 Recap'): 990+ participants, 110 expert speakers, 22 sessions. 2027 edition (organizer target, from current marketing copy): 130 speakers and 29 sessions are stated as goals; these are forward targets, not realized attendance, since registration for 2027 is not yet open.

Worth knowing: Registration and pricing for the 2027 edition are not yet live; the page is currently a save-the-date plus a recap of the January 2026 edition. Re-check closer to Q4 2026 for published price tiers and any early-bird deadline.

Tickets: No pricing or registration tiers are published on the official event page as of 2026-08-25. The page is a save-the-date with only a lead-capture form ('Stay Tuned for Updates about 2027!'); there is no ticket-purchase flow, agenda, or speaker list live yet.

Who's there: Organizer copy targets policymakers, utility executives, generation developers and IPPs, and finance and trading executives. As of late August 2026 the page carries no confirmed speaker list, company roster, or agenda for the 2027 edition; it displays 'Stay Tuned for Updates about 2027!' in place of that content.

Room: Organizer target for the 2027 edition is approximately 800 attendees, stated directly in the event page's marketing copy ('Attend ERCOT Power NEXT along with 800 of your peers'). This is a forward projection, not a reported actual; no prior-year attendance, speaker, or session counts are published on the page.

Worth knowing: As of late August 2026, the event page is essentially a placeholder: no agenda, speakers, attendee recap, or pricing is published, only a save-the-date banner and a lead-capture form. Confirm all details closer to the event.

Tickets: Advance attendee badge registration is free through January 23, 2027. After that date online registrations cost $30, and any attendee badge taken out onsite also costs $30; onsite exhibitor badges cost $10. All prices are in USD; VAT or tax status is not stated. The AHR Education Program, covering industry seminars, panel discussions, rapid-fire new product presentations, for-credit courses, and live podcasts, is free with a show badge. ASHRAE Learning Institute sessions and the concurrent ASHRAE Winter Conference are not included and require separate paid registration.

Who's there: Organizer figures describe engineers, architects, facility managers, contractors, wholesalers, distributors, manufacturer's representatives, OEMs, and design/build professionals across residential, commercial, industrial, and institutional HVACR markets, plus 8,000 international visitors from more than 100 countries and 500-plus international exhibitors among 1,900-plus manufacturers and suppliers exhibiting. No seniority percentage breakdown or total attendee headcount is published on the official site.

Room: The organizer publishes 1,900-plus exhibiting manufacturers and suppliers, 500-plus international exhibitors, and 8,000 international visitors from more than 100 countries. A total attendee headcount, and whether these are 2027 targets or prior-show actuals, is not disclosed on the official site.

Worth knowing: Register by January 23, 2027 to get in free; badges bought later or picked up onsite cost $30. Show hours are 10am to 6pm on January 25 and 26 and 10am to 4pm on January 27. The co-located ASHRAE Winter Conference is a separate paid event, so budget for it if the technical program matters.

Tickets: No visitor, delegate, or exhibitor pricing is published on the official site. Both exhibition stands and delegate registration are gated behind "reserve your stand" and "register your interest" contact forms routed to named sales and delegate contacts, so no ticket price is publicly quoted as of late August 2026.

Who's there: The official site lists the target audience as government ministers and policymakers, C-suite energy executives, engineers and technical professionals, startups, and investors. No published seniority percentage breakdown was found. Organizer marketing for the 2026 edition cites 700+ exhibiting companies and 75,000+ attendees, but this is promotional copy, not an audited post-show report.

Room: Organizer marketing states the 2026 edition drew 75,000+ attendees and 700+ exhibiting companies; this figure is promotional language rather than a verified post-show total. As of late August 2026, the official 2027 site showed placeholder counters with no published attendance target for 2027.

Worth knowing: 2027 attendance and exhibitor targets were not yet published on the official site as of late August 2026. The 2026 figures cited here (75,000+ attendees, 700+ exhibitors) are organizer marketing language rather than an independently audited post-show report.

Tickets: Attendee rates for the 2027 edition are not published as of August 2026; the listing shows only dates and venue and directs questions to [email protected]. No 2027 sponsorship prospectus exists yet either. Prior-year indicative rates from the 2026 prospectus: sponsorship tiers Ally $9,000, Protector $12,000, Steward $17,000, Champion $24,000 (USD), bundling 1-4 complimentary registrations across NACWA's 2026 in-person events. Expect repricing for 2027 and confirm directly with NACWA.

Who's there: NACWA represents more than 350 member utilities serving over 130 million people. Its 2026 sponsorship prospectus states an aggregate figure of 3,000-plus attendees and 75% of attendees being top utility executives, but that figure spans all five of NACWA's 2026 in-person events, not the Winter Conference alone, and no Winter-Conference-specific attendance or seniority breakdown is published. The room is expected to be utility-side (buyers), with vendors, engineering firms, and consultants present mainly as sponsors or exhibitors.

Room: NACWA does not publish a Winter-Conference-specific attendance figure. Its 2026 sponsorship prospectus cites an organizer-stated aggregate of '3k+ Overall event attendees' and '75% of attendees are top utility executives' across all five of NACWA's 2026 in-person events (Winter Conference, National Pretreatment Workshop + Training, Strategic Communication: H2O Workshop, Utility Leadership Conference, and National Clean Water Law & Enforcement Seminar). The same prospectus advertises '133k+ Conference webpage views annually'. These are organizer aggregates for the 2026 event year, not verified actuals for the February 2027 Winter Conference alone.

Worth knowing: A members-first policy and operations meeting; sponsorship is the practical route in for non-member sellers since tiers bundle attendee badges. Venue is the Thompson Houston Hotel.

Tickets: The 2026 edition (most recent published pricing) charged GBP £2,059 ex VAT per individual ticket, with an optional £99 per-ticket delegate protection add-on; group and season-pass pricing were available on request. 2027 tickets are not yet on public sale as of late August 2026; the site currently offers only a "Register Your Interest for 2027" form, with no early-bird deadline published.

Who's there: The organizer describes attendees as C-Level, senior management, project managers, consultants, and key industry stakeholders spanning equipment manufacturers, utilities, oil and gas, software providers, asset owners, PPA and pricing services, engineering firms, banks, institutional investors, and law firms. Exact seniority percentages and named 2027 attendees are not published; the organizer states 2026 attendance represented 12+ European countries including the UK, Germany, France, Spain, Italy, and Poland.

Room: Organizer-stated reach is 12+ European countries represented at the 2026 edition; no absolute delegate headcount is published on the site's public pages for either 2026 or 2027.

Worth knowing: Quoted price of £2,059 ex VAT is the 2026 rate, the latest one Solar Media has actually published; 2027 pricing had not been released as of late August 2026, so budget confirmation should be sought directly from the organizer before relying on this figure.

Tickets: Early bird pricing runs through January 7, 2027: AESP member $1,500, non-member $1,750, government $900. Regular pricing (January 8 to 28): member $1,695, non-member $1,950, government $950. Late pricing (January 29 to February 11): member $1,795, non-member $2,050, government $1,000. All prices are in USD; VAT or tax status is not stated. Registration includes meals, breaks, Wi-Fi, and networking events but excludes hotel, transport, and airfare. Cancellations received on or before January 7, 2027 are refunded minus a $200 processing fee; cancellations after that date and no-shows receive no refund. Partial refunds and member-point re-bookings can carry an additional $50 fee.

Who's there: Attendees are demand-side utility professionals and the vendors and consultants who support them. The organizer states the 2026 conference had confirmed attendees from more than 75 utilities across North America, but no total attendee headcount, seniority percentage breakdown, or named-company list is published on the official site.

Room: Total attendee headcount is not published on the official site. The organizer states the 2026 conference had confirmed attendees from more than 75 utilities across North America; no separate figure or target is given for 2027.

Worth knowing: The refund cutoff is the same day as the early bird cutoff, January 7, 2027, and cancellations must be received by that date to qualify. The organizer's own site now lists this as the AESP Annual Conference 2027 at aesp.org/annual; older listings and third-party calendars may still call it the AESP National Conference.

Tickets: Early registration is $1,895 through the January 24, 2027 deadline, a $100 discount off the $1,995 regular rate. Same-company group rates: $1,950 per person for 3 to 4 registrants, $1,900 for 5 to 9, and $1,800 for 10 or more. An exhibitor package (one table plus one full registration) is $4,200; sponsorships range from $2,000 to $12,000. All prices are in USD; VAT or tax status is not stated. Online registration accepts credit cards only, with check, PO, ACH, and wire transfer available by contacting the registration team.

Who's there: Attendees are described by the organizer as CPG brand owners, resin suppliers, technology providers, equipment manufacturers, and container, closure, and label manufacturers. No seniority percentage breakdown, total attendee headcount, or named-company list is published on the official site.

Room: Exact attendance is not publicly disclosed on the official site. The organizer describes the event as running continuously since 2008 but does not publish a specific attendee count or organizer target for 2027.

Worth knowing: Group rates are keyed to the $1,995 regular price, so the 3-to-4-person rate of $1,950 per seat costs more than the $1,895 early individual rate; small teams should register individually before the January 24, 2027 early deadline. Online registration accepts credit cards only.

Tickets: A day ticket costs 85 euros, 42.50 euros reduced rate. A three-day pass costs 255 euros, 127.50 euros reduced. The pricing page states all prices include statutory VAT. Students and pupils get free admission, but only on the Thursday of the show. No early-bird deadline is published, and the box office accepts card payment only, no cash.

Who's there: The organizer's official post-show release for the February 2026 edition, the most recently completed one, reports 37,000-plus trade visitors, a record, 1,136 exhibitors, up 16 percent and also a record, and representation from 126 nations, up 50 from the prior edition. It states seven in ten visitors are decision makers with purchasing or procurement authority, over 30 percent of exhibiting companies are from outside Germany, and about 30 percent of visitors are international, led by the UK, Netherlands, Switzerland, Italy and Belgium.

Room: The organizer's own press release states the February 2026 edition, the most recently completed one, drew 37,000-plus trade visitors and 1,136 exhibitors from 126 nations, reported as actuals. A separate June 2026 organizer release says the 2027 edition already has 85 percent of exhibition space booked, which is a forward-looking booking indicator, not a confirmed 2027 attendance figure.

Worth knowing: E-world's program explicitly includes natural gas's strategic role in the energy transition alongside renewables, so sellers positioning as pure-play green or carbon-focused should expect a mixed-technology audience rather than a sustainability-only crowd.

Tickets: All figures USD. Registration for 2027 opens in September 2026, so no 2027 rates exist yet. AWWA's page still shows its 2025 card, marked subject to change: full conference $675 (member, early) to $1,000 (non-member, late), single-day passes $350 to $750, students $45 to $75, and pre-conference workshops $140 to $470 depending on half or full day and membership, with the early cutoff at January 9, 2025. The YP Summit ran $170 to $220, with a second $255 to $315 range on the same card; AWWA's 2025 card does not make clear which figure is the standalone rate and which is the UMC-bundled one. The 2026 WEF-hosted edition charged $739 (member, early bird) to $1,349 (non-member, standard) for the full conference, $439 to $689 for one day, and $100 to $225 per workshop, with early-bird pricing ending February 20, 2026. Treat both as historical reference, not 2027 pricing.

Who's there: Utility managers and executives, CFOs and finance directors, public works directors, engineers and project managers, HR professionals, public officials, PR specialists, regulatory staff, and board members, per AWWA's own who-attends list. This is buyer-side water utility leadership, not a vendor crowd. The conference is co-located with the Young Professionals Summit and sells a combined ticket for it. Neither host association publishes attendance figures.

Room: Neither AWWA nor WEF publishes attendance totals. The 2026 edition, WEF-hosted in Charlotte on March 24-27, 2026, ran 34 technical sessions and 7 pre-conference workshops, which puts it at mid-size executive conference scale rather than trade show scale. The 2027 edition returns to AWWA hosting in Vancouver.

Worth knowing: Registration and program details live with whichever association hosts that year, so 2027 details sit on awwa.org while 2026 details remain on wef.org. Check the AWWA page from September 2026 for confirmed 2027 rates.

Tickets: Official All-Access Pass pricing in USD (tax/VAT status not stated on the pricing page) per the GreenBiz 27 registration page: Launch Rate $2,995 through August 28, 2026; Best Rate $3,995 through November 13, 2026; Advance Rate $4,295 through January 22, 2027; Standard Rate $4,695 through February 19, 2027; Final Rate $4,895 from February 20 to 25, 2027. A 20% discount applies to government employees, academics and students, startups, and nonprofits; startups must be fewer than 10 years old with $30M or less in funding, and nonprofits must have an annual organizational budget of $20 million or less. The discount cannot be combined with other offers and cannot be applied retroactively. Complimentary press passes are available in limited numbers to journalists covering sustainable business, require professional credentials submitted to [email protected], and are not open to business development, sales, marketing, or research staff.

Who's there: The organizer states GreenBiz 27 will bring together 2,000 corporate sustainability leaders and practitioners, with 77% at manager-level or above, 50% from companies with $100M-plus annual revenue, and 30% from companies with $1B-plus revenue. Roles cited span CSOs, corporate responsibility, net-zero, finance, EHS, and communications staff, i.e., overwhelmingly buyer-side practitioners. Companies named as represented include Mastercard, General Motors, Google, Adobe, Patagonia, and L'Oréal.

Room: Organizer-published target for the upcoming edition is 2,000 attendees. This figure appears on GreenBiz 27's own marketing page describing the anticipated February 2027 audience; it is an organizer projection/description for the upcoming show, not a verified post-show actual, since no post-show attendance report exists for any prior GreenBiz edition.

Worth knowing: Hotel rooms at the Gaylord Pacific start at $369/night per the official event page. The $2,995 Launch Rate expires August 28, 2026, after which the entry price becomes the $3,995 Best Rate, itself good through November 13, 2026. Pricing then rises in four further steps through February 2027, so sellers building a 2027 events budget should lock the rate early.

Tickets: Published tiers (GBP, prices subject to VAT where applicable, no early-bird deadline stated) are: Virtual Pass £495, Start-ups £995, Academics and Government £1,295, and a complimentary pass for qualifying utilities. The start-up, academic, government, and utility rates carry eligibility criteria and require contacting the organizer to qualify. No standard corporate, solution-provider, or technology-vendor in-person price is listed on the registration page, so most B2B sellers would need to request a quote. On cancellations, the organizer charges a 15% cancellation fee if you cancel at least 30 days before the event date, accepts no cancellations after that point with full payment due, and welcomes substitutions at any time.

Who's there: The organizer expects 500+ delegates, with 75% at CEO or Director level, 80+ speakers, and 35+ countries represented. Named speakers and partner organizations cited by the organizer include Veolia, Schneider Electric, Xylem, Northumbrian Water, Scottish Water, Severn Trent Water, British Water, the Environment Agency, DEFRA, the Water Research Foundation, Tokyo Metropolitan Government, Arcadis, Arup, Esri, and HydroDigital.

Room: The organizer projects 500+ delegates, 80+ speakers, and 35+ countries for the 2027 edition, with 75% of attendees at CEO or Director level. These are forward-looking organizer figures rather than audited results, since the event has not yet taken place.

Worth knowing: The registration page still carries some prior-year content: a virtual platform access date of March 25, 2026, plus 2026 agenda, key themes, and recap entries in its navigation. It also lists no standard vendor or solution-provider ticket price, so sellers should confirm their applicable rate directly with the organizer before booking. The venue is listed consistently as Convene 155 Bishopsgate across the organizer's pages.

Tickets: No registration pricing is published for the Policy Forum on ACORE's event page or its registration subpage as of August 2026. A sibling ACORE event (the Finance Forum) has a live, priced registration page, but the Policy Forum's does not, so attendance likely runs through ACORE membership and Executive Council or Premier sponsorship allocations rather than open ticket sales. Sellers should contact ACORE directly, including via its sponsorship inquiry form, for cost.

Who's there: ACORE states 50% of Policy Forum attendees are C-Suite, VP, or Director-level. The room is senior and mostly buyer and investor side: policymakers, corporate leaders, investors, utilities, and clean energy innovators. Published Executive Council sponsors (30-plus companies) include Amazon, Google, JPMorgan, Goldman Sachs, Berkshire Hathaway Energy, and NextEra Energy, with Premier sponsors including Advanced Energy United, Dominion Energy, and Wood Mackenzie; these are sponsor listings rather than a confirmed attendee roster, and total attendance is not published.

Room: No attendance figure, past actual or 2027 target, is published on ACORE's Policy Forum page. The 50% C-Suite/VP/Director statistic is the only audience-composition figure disclosed.

Worth knowing: The prior edition of this event ran February 25-26, 2026 in Washington, D.C.; the 2027 edition moves slightly earlier to February 24-25, 2027. A specific venue or host hotel for the 2027 edition was not named on the official page as of late August 2026.

Tickets: No tier prices are published yet. The official registration page states that registration is scheduled to open in fall 2026 and that badge costs differ by pass type, listing Utility, General, Solution Provider, Exhibitor, Groups through the Utility Partner Program, and Press/Media tiers. The only amounts currently published are a USD 125 spouse add-on covering the exhibit hall, opening keynote, opening party, and networking party, and a USD 110 administrative charge deducted from refunds. Cancellations must be received in writing by January 8, 2027 to qualify for a refund, and no refunds are available after that date. The page also separates an All Access Pass covering the full educational program of technical sessions, workshops, Grid University, roundtables, networking events, and PDH eligibility from a cheaper Expo-Only Pass limited to the exhibit hall, keynotes, Knowledge Hubs, and welcome receptions.

Who's there: The official site publishes headline figures of 18,000 plus professionals, 684 exhibitors, 490 plus speakers, and 800 plus utility attendees, with Southern Company named as 2027 host utility and Itron as the presenting sponsor. The organizer groups attendees into four buyer categories: utilities, consultants, finance and investment professionals, and EPC firms. No seniority percentage breakdown or named attendee list beyond the host utility and sponsor roster is published.

Room: The official 2027 site publishes 18,000 plus professionals, 684 exhibitors, 490 plus speakers, and 800 plus utility attendees. These are the organizer's headline figures for the show and are not labeled as either confirmed 2027 registrations or prior-edition actuals.

Worth knowing: Registration opens in fall 2026, so no seller-tier price can be budgeted yet. Cost varies by pass type and by All Access versus Expo-Only access, and the January 8, 2027 refund cutoff falls roughly seven weeks before the show opens.

Tickets: No ticket price, currency, VAT status, or early-bird deadline is published on the event's public pages; the site publishes no working registration or passes page and directs prospective attendees to register interest or contact organizers directly. This is consistent with Economist Impact's typical model of vetted or invite-based corporate passes rather than open online ticket sales.

Who's there: The event targets senior corporate decision-makers, described by the organizer as chief sustainability officers, chief procurement officers, chief financial officers, and chief executives. The 2026 edition drew 2,234 registrations from 937 unique organizations across 56 countries and 17 industries, which the organizer cites as the baseline the 2027 edition is built on.

Room: Organizer target for 2027 is stated as drawing over 2,500 industry leaders; the most recent reported figure is 2,234 registrations from 937 organizations across 56 countries at the 2026 edition, organizer-reported on its own event page rather than independently audited.

Worth knowing: Public pricing pages for this event consistently 404 as of late August 2026; readers who need budget numbers should contact Economist Impact directly rather than relying on a third-party estimate.

Tickets: One registration covers all three co-located conferences and is tiered by booking date. The current rate is the 1,020 USD early bird, available through 30 September 2026; the 900 USD earliest-bird tier closed on 30 June 2026. Standard registration is 1,095 USD from 1 October 2026 through 28 February 2027, and walk-up registration is 1,450 USD on 1-3 March 2027 if the event has not sold out. Registration covers all sessions, exhibit hall entry, hosted receptions and meal functions, the conference app, and the attendee list. No exhibit-hall-only or one-day passes are offered, and registration excludes lodging and airfare. VAT or sales tax status is not stated, which is normal for a US domestic conference.

Who's there: The organizer markets 2,500+ attendees and 250+ exhibitors across the combined PRC/RRC/TRS event, drawn from plastics processors, converters, global consumer brands, resin manufacturers, trade groups, sustainability and policy teams, and materials-recovery operators. The "Who Attends Our Conferences" breakdown is published only as an infographic image, so no numeric role or seniority split could be extracted as text.

Room: The organizer markets 2,500+ attendees and 250+ exhibitors across the combined PRC/RRC/TRS event. These are organizer-published targets, not independently verified counts for the March 2027 edition, which has not yet occurred.

Worth knowing: Book before 30 September 2026 to hold the 1,020 USD early-bird rate; it rises to 1,095 USD on 1 October. No exhibit-hall-only or single-day passes are sold, so the full 3-day, 3-conference registration is the only way in. The registration page still labels the expired 900 USD tier as running "now through June 30," so read the tier dates rather than the label.

Tickets: 2027 registration rates had not been published as of late August 2026, and registration was not open. For reference, the 2026 Symposium in Los Angeles (March 8-11, 2026) charged a final onsite rate, in effect February 19 to March 11, of $1,400 for WateReuse members and $1,900 for non-members in USD. Special rates ran $950 for speakers, $450 for students, $950 for Regulator Summit attendees, and a one-day pass at $800 early bird, $900 advanced, or $1,000 onsite. Offsite tours and the Tuesday evening networking event were $65 each. For 2027, a discounted Caesars Palace room rate of $259 per night plus tax runs October 6, 2026 to February 7, 2027, or until the room block fills. VAT status is not stated (US-based event).

Who's there: Water utility staff, engineers, regulators, researchers, and water reuse technology and service providers, drawn from across the US and internationally. Trade press coverage of the 2025 Symposium (its 40th anniversary) put attendance at more than 1,000 water industry professionals. The organizer does not publish per-edition headcounts, and no figure is available yet for 2027.

Room: Trade press put the 2025 Symposium (40th annual) at more than 1,000 attendees. No attendance figure is available for 2027, and registration had not opened as of late August 2026.

Worth knowing: Registration for the 2027 edition was not open as of late August 2026. Watch the event page for early-bird windows, and book the Caesars Palace block early since it closes when the rooms sell out.

Tickets: Fees are published in euros with 10% VAT added and no early-bird deadline. An all-conferences pass covering 2 to 5 March 2027 is 430 euros. Single-conference passes range from 70 to 385 euros. At 70 euros each are the Energy Efficiency Policy Conference (4 March), the Workshop One-Stop Shops (3 March), and the Young Energy Researchers Conference (2 March), all one day. The European Energy Efficiency Conference (3 to 5 March) is 385 euros, the European Pellet Conference (3 March) is 250 euros, and the Industrial Energy Transition Conference (4 March) and Smart E-Mobility Conference (5 March) are 130 euros each. Student rates run from 35 euros for the one-day conferences to 65 euros for the Pellet and Energy Efficiency conferences and 125 euros for the all-conferences pass. All fees include an entrance ticket to the tradeshow and conference documentation. The site does not publish a standalone tradeshow admission price.

Who's there: The organizer describes the audience as business actors in the energy transition (energy companies, technology vendors, equipment suppliers, service providers, project developers, financing professionals), researchers and academics, and public-sector representatives from EU institutions and national, regional, and local governments. The organizer states over 650 participants from more than 60 countries attend annually, though this is a general recurring claim rather than a figure tied to a specific past edition.

Room: The organizer states over 650 participants from more than 60 countries as a standing annual figure rather than a count tied to any one edition. The reviews page links per-edition conference review PDFs for 2024, 2025, and 2026 for anyone who wants a specific year's numbers.

Worth knowing: Seven sub-conferences run in overlapping one-day and multi-day windows between 2 and 5 March at Stadthalle Wels, and a single-conference pass does not grant access to the others, so check the per-conference schedule before booking travel. The tradeshow runs 3 to 7 March, extending past the end of the conference program.

Tickets: As of the official registration page, CERAWeek 2027 registration is listed as 'coming soon,' with only a notify-me signup available. No pricing tiers, currency, early-bird deadlines, or VAT status have been published for the 2027 edition.

Who's there: According to CERAWeek's own about page, the 2026 edition drew about 2,470 companies, roughly 2,200 C-suite leaders, 588 government officials including 67 ministers, more than 1,400 speakers, and about 450 media representatives from around 90 countries. A separate homepage summary cites over 10,000 total participants, 84 ministers, 365 media, and representatives from 2,350-plus companies across 89 countries for the same edition; both figures are organizer-reported, not independently audited, and the two pages do not fully reconcile. The audience skews heavily toward oil, gas, utility, and government energy-policy leaders rather than pure-play sustainability buyers.

Room: CERAWeek 2026, the most recent completed edition, drew over 10,000 total participants per the organizer's own recap. No attendance figure or target has yet been published for the 2027 edition.

Worth knowing: Specific 2027 venue/hotel name was not published on the official site as of late August 2026; only the city (Houston) and dates were confirmed. The two organizer pages cited for 2026 attendance report different topline numbers, both are used here with that caveat.

Tickets: Anniversary Super Early Bird rates, in USD: $999 for the in-person delegate pass, $999 for the on-demand virtual replay pass, and $1,249 for the pass plus workshop access. The registration page dates this tier to September 15, 2026, while the event homepage advertises the $999 rate through September 14, so book against the earlier date. Standard and later-tier pricing had not been published as of late August 2026. VAT status is not stated (US-based event).

Who's there: The room covers the packaging value chain: raw material suppliers, packaging converters, retailers, brands, government agencies, NGOs, and academia. Common job titles include Director of Sustainability, Director of Packaging, Corporate Sustainability Leader, and Packaging Engineer. Past attendee companies listed by the organizer include General Mills, PepsiCo, Kraft Heinz, Unilever, Nestle, Mars, P&G, Mondelez, Church & Dwight, and Costco.

Room: No attendance figure is published. The organizer lists attendee companies and job titles instead of a headcount. The most recent prior edition ran March 10-12, 2026 in Chicago.

Worth knowing: The 2027 edition moves to Dallas, TX, for the event's 20th anniversary. The 2026 edition ran in Chicago, so returning attendees and exhibitors are booking a new city.

Tickets: Online visitor registration is free of charge for trade visitors. A same-day, on-site ticket costs 75 euros per the official FAQ. VAT status is not stated on the official site, and no separate paid pricing for conference tracks such as the Innovation Forum was published. Entry is restricted to trade visitors aged 16 and older; the general public is not admitted.

Who's there: The prior 2025 edition drew 25,000-plus visitors, 850-plus exhibiting companies and representation from 140-plus countries per the organizer's own recap, with entry restricted to trade visitors aged 16 and over. No published breakdown of attendee job titles, seniority or buyer-to-seller ratio was found on the official site. Content is organized into five program tracks called Worlds: Industrial and Corporate Water, Digital and AI, Clean Water, Urban Resilience, and Wastewater and Resources.

Room: The organizer reports the 2025 edition, the most recently completed one, drew 25,000-plus visitors and 850-plus exhibiting companies from 140-plus countries, presented as an actual result. Separate 2027 marketing copy anticipates over 25,000 visitors and about 900 exhibiting companies, and general event copy cites a baseline of 22,000-plus visitors and 900 exhibitors every other year; these forward-looking figures are organizer expectations, not a confirmed 2027 actual.

Worth knowing: Aquatech Amsterdam runs on a two-year cycle rather than annually, so this March 2027 edition is the next occurrence after the 2025 show, not an annual return.

Tickets: Visitor tickets are trade-show entry passes rather than conference registrations, priced in EUR. Purchased online before the show: 3-day pass EUR 30, reduced 1-day pass EUR 18. Online during the show: 3-day pass EUR 40, full 1-day pass EUR 25. At the venue: 3-day pass EUR 45, full 1-day pass EUR 28. Free for children under 12, discounted for ages 12-18. The ticket pages do not state VAT status. A separate Hosted Buyer program (subsidized travel, accommodation, and lounge access) is open to qualified international delegates by application.

Who's there: Per IEG's official March 2026 results release: total attendance grew 10% year over year with foreign visitors up 9%; more than 1,000 exhibiting brands (320 international); 530 hosted buyers and delegations from 59 countries; 412 accredited journalists; 160 conference sessions across 125,000 sqm and 24 halls. Independent trade-fair directories put 2026 total visitors at roughly 71,000, a figure the organizer's own materials reviewed do not confirm.

Room: 2026 edition (organizer-reported): total attendance up 10% year over year, foreign visitors up 9%; 1,000+ exhibiting brands (320 international); 530 hosted buyers/delegations from 59 countries; 412 accredited journalists. Third-party trade-fair listings cite roughly 71,000 total visitors for 2026, a figure not found on IEG's own pages reviewed.

Worth knowing: Dates confirmed as March 10-12, 2027 (three days) by the official FAQ and press release. The entry ticket covers badge access only; exhibiting or Hosted Buyer participation involves separate cost or application. KEY overlaps thematically with sibling IEG events SSEC (Storage & Solar Expo Conference, Sept 2026, Vicenza) and Ecomondo (Nov 2026, Rimini).

Tickets: As of the current event page, registration pricing for the 2027 edition is not yet published. The page displays 'Stay Tuned for Updates about 2027' in place of ticket tiers, so no currency, early-bird deadline, or VAT status is available.

Who's there: Infocast describes the audience as C-suite executives from banks and investment firms, solar and wind developers, EPC companies, law firms and consultants, insurance providers, alternative finance organizations, and equipment suppliers. Per Infocast's own recap on the event page, the 2026 edition drew more than 3,900 industry leaders, over 200 speakers, more than 35 sessions, and more than 230 sponsors and exhibitors.

Room: Infocast's own 2026 recap reports more than 3,900 industry leaders, over 200 speakers, more than 35 sessions, and more than 230 sponsors and exhibitors for that edition. No attendance figure or target has yet been published for the 2027 edition.

Worth knowing: The 3,900-plus attendee figure is Infocast's own reported total for the 2026 edition of this specific summit (confirmed as summit-specific, not a bundled multi-event week), and is organizer-reported rather than independently audited. Pricing for 2027 had not been released as of late August 2026.

Tickets: The organizer publishes no visitor ticket price and no exhibitor stand or sponsorship rates. The ticket page offers a registration form without showing a price, and exhibitor pricing is available only by contacting the sales team directly or through the organizer's private Event Planner portal.

Who's there: The organizer describes the event as targeting installers, developers, and other professionals in the solar, storage, and EV charging industries, and states over 300 exhibitors participate, including sponsors such as Alpha ESS, FelicitySolar, GoodWe, and Huawei. The organizer publishes no visitor headcount, seniority breakdown, or buyer-versus-seller ratio.

Room: The organizer states more than 300 exhibitors, more than 500 innovations on display, and over 50 practical seminars. No visitor attendance figure for a past edition is published.

Worth knowing: The practical-information page still carries a 2026 year label on its opening hours, but its weekday names (Tuesday 16, Wednesday 17, Thursday 18 March) match 2027 rather than 2026, and both the English and Dutch homepages state 16 to 18 March 2027. Treat the 2027 dates as authoritative. Doors are 10:00 to 17:00 each day at Expo Greater Amsterdam, Stelling 1, 2141 SB Vijfhuizen, roughly 20 km west of central Amsterdam, so budget travel time from the city.

Tickets: Visitor registration and VIP registration (for manager-level attendees and above) are both listed as free on the official registration pages. No paid conference-only ticket was found. Exhibitor stand pricing is not published and requires contacting the sales team via the exhibitor information download on the official site.

Who's there: The official site describes the expected visitor base as electric power and gas companies, oil and chemical manufacturers, heavy industry and automotive manufacturers, and government agencies. VIP registration is reserved for attendees at manager level or above, so the buyer skew is mid-to-senior, though no exact seniority percentage is published.

Room: The official site forecasts roughly 122,000 visitors, 2,380 exhibitors, 380 conference sessions and attendees from 63 countries. These figures are organizer projections for the entire 2026-2027 World Smart Energy Week show series across all its co-located venues and events, not a verified actual count isolated to the Spring Tokyo edition alone.

Worth knowing: The 122,000-visitor, 2,380-exhibitor and 63-country figures are organizer forecasts for the full 2026-2027 World Smart Energy Week show series across all venues, not a verified count for the Spring Tokyo edition specifically.

Tickets: The official site provides a visitor registration form but does not publish visitor entry fees, badge costs, or any conference-session pricing anywhere on the site, including the dedicated registration and fact-sheet pages. The organizer directs visitors to contact them directly ([email protected], +971 4 340 6888) for cost details, so pricing cannot be quoted without guessing.

Who's there: The organizer lists 24 target visitor profiles spanning the full supply chain, including factory owners and operators, production and plant managers, engineers, R&D professionals, raw material and chemical suppliers, distributors, traders, automotive and tire manufacturers, consultants, and investors. The 2025 edition drew 770 plus exhibitors and 27,776 plus total footfall, with visitors from 141 plus countries and 32 plus countries represented among exhibitors. No published seniority percentages or named attendee companies were found on the official site.

Room: 27,776 plus total footfall and 770 plus exhibitors from 32 plus participating countries at the 2025 edition, per organizer-published fact sheet figures for the prior edition. No 2027 target figures are published yet.

Worth knowing: This is a plastics and petrochemicals industrial trade show, not a dedicated sustainability event, so most of the floor and audience will be outside a carbon or ESG seller's core buyer persona; the relevant niche is the recycling and packaging circularity track specifically.

Tickets: Conference delegate passes are quoted in US dollars, and every published rate is an early-bird rate. An All Access Pass covering both the Strategic and Technical Conferences costs 2,420 dollars, a Strategic Conference-only pass costs 1,680 dollars, and a Technical Conference-only pass costs 958 dollars. Each includes delegate lunch on all three days, delegate lounge access, a bag, the mobile app, the Innovation and AI Hub, and general exhibition access, per the official delegate registration page. The page gives the deadline only as Monday 26 October with no year, but 26 October falls on a Monday in 2026 and on a Tuesday in 2027, so the early-bird cutoff is 26 October 2026. No standard or post-deadline rate is published, and VAT or tax treatment is not stated. General exhibition-floor visitor registration is offered separately, and no price for it appears on the public visitor registration page.

Who's there: The organizer expects 60,000 total attendees, 2,500 conference delegates, and 600 exhibiting companies. The published exhibitor list runs well past 100 companies and includes BP, SLB, Halliburton, Apache, Energean, Methanex, Schneider Electric, Bureau Veritas, and Egyptian state companies such as ENPPI, Petrojet, GASCO, MIDOR, and Egyptian Drilling. The conference program splits into a Strategic Conference of 40 executive-level sessions across 10 programs covering global energy markets, gas and LNG, renewables and low-carbon solutions, decarbonisation, and finance and investment, and a Technical Conference for applied and operational content, both open to registered delegates.

Room: The organizer's 2027 pages state that the show will welcome 60,000 attendees, 2,500 conference delegates, and 600 exhibiting companies. This phrasing reads as an organizer target for the 2027 edition rather than a verified actual, and no prior-year actual attendance figure is published for comparison.

Worth knowing: Every delegate rate on the official page is an early-bird rate expiring 26 October 2026, and no standard rate is published, so the cost of registering after that date is unknown. VAT and tax treatment are not stated either, so confirm both with organizers before booking.

Tickets: No public price list appears on the official event site. Its navigation has no register or prices page (a direct URL guess for one returned a 404), and registration runs through Informa's registrations team ([email protected]) or a requested brochure and quote. Third-party listings reference a 20% partner discount code and a 35% EXPRA-member discount off the standard rate, which points to negotiated or tiered pricing rather than one published rate.

Who's there: Companies registered to attend recent editions include the European Commission, European Parliament, Amazon, P&G, BASF, Nestle, Coca-Cola, Heineken, Henkel, IKEA, LEGO, METRO, Honeywell, ExxonMobil, Roche, Abbott, Aldi, SAP, Crown, and DS Smith, alongside EPR and producer-responsibility bodies (Citeo, Fost Plus, CONAI, EXPRA, EUROPEN, Landbell Group) and trade associations (European Container Glass Federation FEVE, CropLife Europe, Ecommerce Europe). The room mixes regulators, brand-owner packaging teams, waste managers, and material suppliers rather than one buyer type.

Room: Informa's own event marketing describes the 2026 edition as 'over 150 attendees, including end users' and used '100+ attendees' language for the 2025 edition. No independently audited attendance figure appears on the official event pages, so treat both as organizer marketing copy rather than verified counts.

Worth knowing: The venue is a hotel (Thon Hotel Bristol Stephanie) rather than a convention center, which fits the forum's smaller scale next to the larger EU packaging trade shows.

Tickets: First release tickets are live, with GBP 200 off every tier until December 4, 2026. Per-person GBP rates: edie Members GBP 349 (GBP 549 full price); Corporate, 50+ employees, GBP 499 (GBP 699 full); Small Business, up to 50 employees, GBP 399 (GBP 599 full); NGOs/charities/academics/public sector GBP 399 (GBP 599 full); Solution Provider (consultants/vendors) GBP 699 (GBP 899 full). Every tier also offers a group rate of four tickets for the price of three. The pricing page does not state VAT treatment.

Who's there: The audience is sustainability, energy, procurement, and ESG reporting leaders at UK and European companies, alongside NGOs, academics, public sector bodies, and solution providers or consultants. The five ticket tiers (edie Members, Corporate 50+ employees, Small Business, NGOs/charities/academics/public sector, and Solution Provider) map directly to that buyer mix, and the dedicated Solution Provider rate shows vendors are an expected part of the room. The organizer states edie 27 delivers 1,000-plus opportunities to connect and that 87% of attendees leave with clear next steps, without publishing an audited headcount.

Room: The organizer states edie 27 delivers 'TWO days, 1,000 opportunities to connect, collaborate and act' and that 87% of attendees leave with clear next steps. No audited attendee headcount appears on the official site. edie dates the event to 1998 and claims 26 years shaping the sustainable business agenda, with the '27' in the name marking the 2027 edition rather than an edition count.

Worth knowing: First release pricing runs through December 4, 2026, roughly four months before the event, so booking early saves GBP 200 per ticket.

Tickets: Attendee registration for the 2027 event has not opened as of August 2026, and no ticket prices are published. The official key-dates list states "Registration opens: December 2026." Exhibition stand sales opened in March 2026, and the conference call for abstracts closes 4 September 2026.

Who's there: Organizer projects 16,000+ participants, 500+ exhibitors, 80+ sessions, 400+ speakers and 200+ posters for the 2027 edition. Site testimonials come from Vattenfall (VP Partnerships & Business Transformation, Business Area Wind), Nordex Acciona (Global Public Affairs) and RWE (Director Strategy, Regulatory Affairs & Business Transformation). That points to a room of utilities, turbine OEMs, developers and policymakers across the European wind value chain.

Room: Organizer projects 16,000+ participants for the 2027 edition. The event has not happened yet, so that is a forward-looking organizer figure rather than an audited actual.

Tickets: Ticket pricing for the 2027 edition (26-28 April 2027) is not published as of August 2026. The homepage and the official summit page both offer only a pre-registration interest form for notification when registration opens, with no price tiers, currency or deadlines listed.

Who's there: The organizer repeats the same figures across the site: roughly 40,000 attendees, 10,000 companies, 1,000 solutions and startups, 1,400 investors, and 500+ media from 140 countries. Named corporate partners and speakers include chief sustainability and CSR officers from L'Oréal, Kering, Saint-Gobain, AXA, Engie, Orange, Accor and KPMG, alongside government officials, UN representatives and NGO leaders. The site splits its audience into Company, C-Level, Investor, Startup, Ecosystem partner, Policy Maker, Volunteer and General Public tracks.

Room: Organizer states roughly 40,000 attendees and 10,000 companies, figures that recur across the site. They describe the ChangeNOW franchise in general rather than an independently audited count, and the 2027 edition has not yet occurred.

Worth knowing: ChangeNOW mixes B2B programming with public-facing content, including a dedicated General Public track and startup pitch events, so the room holds founders, NGOs, media and the public alongside corporate buyers.

Tickets: Registration for Trellis Impact 27 has not opened as of August 2026. The official site says "Registration opens soon" and offers only an email signup for launch notification, so no price tiers are published yet. Once purchased, registrations are non-refundable, but they can be transferred to a colleague or converted into a credit memo toward a future Trellis Group event within one year.

Who's there: The organizer states 2,000+ attendees, 400+ speakers, and 100+ sessions. Past attendee titles skew corporate sustainability leadership: Global Head of Sustainability (Adobe), Senior Sustainability Manager (Amazon), Senior Director Climate (Atlassian), VP Circular Economy (L'Oréal), Global Head of Net Zero & Sustainability (Meta), and Director Energy Portfolio Management (Walmart), plus attendees from Apple, Disney, Google, NVIDIA, Goldman Sachs, PG&E, Stripe, Salesforce and McDonald's.

Room: Organizer projection for the 2027 edition: 2,000+ attendees. That is a forward-looking organizer figure, not an audited actual, since the event has not yet occurred.

Worth knowing: The main-stage keynote program is livestreamed, but there is no full virtual-attendance ticket. Breakout, workshop and tutorial sessions are in-person only and audio-recorded, and the organizer does not publish those recordings or transcripts.

Tickets: No 2027 rate is published yet. Registration has not opened, and the site currently collects expressions of interest only. Recent editions have been free for trade visitors: the official site promotes free access to sessions across its show floor theaters, and its own attendee testimonials cite free entry as a reason to come. Whether the Strategic Summit carries a separate fee in 2027 is not stated. Exhibiting costs are not published as a rate card.

Who's there: Energy developers, utilities, investors, policymakers, and technology vendors across renewables, hydrogen, and grid infrastructure. The 2025 edition drew more than 13,000 attendees over two days, a record, up from 11,736 in 2024, with over 300 exhibiting organizations and nearly 600 speakers, per organizer RX. Named 2025 exhibitors included ScottishPower, SSEN Transmission, Hitachi Energy UK, Vattenfall, Statkraft, RWE Generation, Innovate UK, and ABB. Keynote sessions have drawn Scotland's Deputy First Minister and the head of the UK government's Clean Power 2030 mission control, so senior policy and utility leadership is in the room. Feature areas include a Scale-Up Zone, an Innovators Hub, a Meet the Buyer program, and the Giant Networking Evening.

Room: The official site lists its most recent edition at 13,300+ energy professionals, 310+ exhibiting companies, 3,500 companies represented, and 56 countries, without dating that set. All-Energy runs annually, so the May 2026 edition has already taken place and those headline figures may describe 2026 rather than 2025. Per RX, the 2025 edition (May 14-15, 2025) drew more than 13,000 attendees over two days, up from 11,736 in 2024, alongside over 300 exhibiting organizations and nearly 600 speakers across the conference, seven show floor theaters, and the academic poster program.

Tickets: Attendee registration pricing for 2027 is not published. ACP has not opened 2027 registration, and the exhibitor page refers to "Rates & Special Discounts" without exposing attendee ticket tiers outside an account login. Check the site closer to the event for confirmed rates.

Who's there: 2026 actuals (Houston, organizer-reported): 8,000 attendees, of whom ACP states more than 70% are involved in final purchasing decisions; 500 exhibitors; 200 speakers; attendees from 50 US states and 35+ countries. The 2026 sessions covered market outlook, large loads and data centers, tariff strategy, siting and permitting, capital allocation, and state policy. No 2027 audience figures are published yet, since the event has not occurred.

Room: 2026 edition (Houston, organizer-reported actuals): 8,000 attendees, 500 exhibitors, 200 speakers, attendees from 50 states and 35+ countries. 2027 (Anaheim) attendance has not been reported, as the event has not taken place.

Worth knowing: Sister event CLEANPOWER in Color runs alongside it on the same Anaheim dates. EmpowHER 2027 is a separate ACP event listed only as summer 2027, with dates and city still to be announced, so do not plan on covering both in one trip. The next CLEANPOWER edition is already announced for Philadelphia, May 8-11, 2028.

Tickets: ACE27 registration is not yet open, and the Call for Abstracts runs through September 10, 2026, for the June 2027 event, so no ACE27-specific rates are published. The most recent published cycle, ACE26 (Washington DC, June 21-24, 2026), listed onsite rates of $1,350 member / $1,750 non-member (USD) for full-conference access, $950/$1,250 for one-day passes, $350/$450 for exhibits-only, and $80/$110 for verified students, with advance rates lower. Pre-conference workshops cost $385-$490 for members, $470-$590 for non-members, and $80-$130 for students, and Public Officials courses run $185 member / $285 non-member per course. ACE27 rates should land in a similar range.

Who's there: The room is mostly drinking water and wastewater utility staff (engineers, operators, plant managers), consulting engineers, and public officials, spread across 20+ educational tracks and hundreds of technical sessions. Sponsors of the most recent edition include Xylem, Mueller Water Products, Kamstrup, Brita, Arup, and WSSC Water. AWWA markets ACE as one of the oldest and largest water conferences in the world and North America's largest annual drinking water conference.

Room: ACE25 (2025, Denver) drew 8,109 attendees and 433 exhibiting companies across 1,100 booths (105 international), for 11,403 total registrants including exhibitor staff, per AWWA's official ACE25 Stats & Metrics recap. No ACE27 (San Diego) attendance figure exists yet, since registration is not open.

Worth knowing: The Call for Abstracts for ACE27 closes September 10, 2026, which matters if you want a speaking slot rather than a booth.

Tickets: London Climate Action Week has no central ticket or entry fee. It is a platform of hundreds of independently organized events, each priced (or not) by its own host. Community and borough events are typically free, while flagship conferences and specific hosted sessions may charge their own fees. No unified price list exists, because LCAW does not sell tickets on behalf of its hosts.

Who's there: The 2026 edition, the most recent completed one, drew 100,000+ participants across 1,300+ events, with 100+ countries and 25 governments represented across 6 continents, 30 flagship events, and 13 hubs. Hosts range from the London Stock Exchange, Westminster, and the Excel Centre to borough sustainability festivals and community groups. No single organizer curates attendee seniority, since each event sets its own guest list.

Room: 2026 edition actuals, per the official post-event recap: 100,000+ participants, 1,300+ events, 100+ countries, 25 governments across 6 continents, 30 flagship events, 13 hubs. The official site describes 2026 as the eighth edition, which makes June 2027 the ninth. No attendance figures for 2027 are published yet; the site currently carries only a save-the-date.

Worth knowing: Only the dates, 19-27 June 2027, are confirmed on the official site. The 2027 program, hub list, and individual event pricing are not published yet. Included on scale and reputation rather than on the density of published program detail, since the 2027 program is still unannounced.

Tickets: No attendee price appears on the official 2027 site, and visitor registration has not opened yet. Exhibitor-side costs are published in euros: sponsorship packages run EUR 6,500 (Silver) to EUR 8,000 (Gold) and EUR 16,000 (Platinum Event Sponsorship), with the registration desk at EUR 5,000, visitor badge branding at EUR 4,000, lanyards at EUR 4,500, and event app placements from EUR 1,000 to EUR 2,500. VAT treatment is not stated.

Who's there: Plastic recyclers and material suppliers, recycling machinery and equipment vendors, pre-processors, handling and logistics providers, waste management firms, local authorities, and project management consultants, per the event's own visitor breakdown. The 2027 program adds a textiles recycling feature alongside the two-theater conference and the Plastics Recycling Awards Europe. Visitors to the 2026 edition came from 109 countries. Entry is trade only: you need a pre-registered visitor or exhibitor badge, no one under 16 is admitted, and non-exhibiting companies are asked not to solicit business on the floor.

Room: No exhibitor or attendee totals are published for 2027. The organizer describes PRSE as the largest dedicated plastics recycling exhibition, conference and awards in the world, and its Visit page reports that 2026 visitors represented 109 countries. The May 2026 show was the 10th anniversary edition; 2027 is the 11th.

Worth knowing: The free band is provisional. No visitor fee appears anywhere on prseventeurope.com, but 2027 registration has not opened, so a free trade-visitor badge is likely rather than confirmed. Recheck the Visit page once registration goes live.
