ESG conferences 2026–2027

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: The current organizer header and event-format section both show October 6 and 7; the saved single-day listing was superseded.

Tickets: Book by September 18, 2026: corporate pass GBP 1,999; solution-provider pass GBP 3,749, subject to applicable taxes. Listed subsequent rates are GBP 2,199 and GBP 3,999. Consultancies, advisors, data and technology providers use the solution-provider category.

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: 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.
