01 / Make the call
Is this the right room?
Emitree's assessment of audience fit. Conference access does not establish buying intent or guarantee meetings.
Consider it if
You sell to corporate sustainability, CSR or ESG-consulting buyers across any vertical (climate, circularity, biodiversity, mobility) and want breadth over depth. Large-cap sustainability officers from L'Oréal, Kering, Saint-Gobain, AXA and Engie attend alongside 1,400 investors and thousands of startups in one venue.
Consider another event if
You need a narrow technical buyer audience in one vertical, such as compliance carbon trading or wind procurement. ChangeNOW is broad and partly public-facing, so a niche B2B pitch fights more noise here than at a specialist trade conference.
02 / Understand the audience
Who attends
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.
How large is the event?
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.

The practical questions
Before you decide
Is ChangeNOW 2027 still upcoming?
This edition is listed for April 26–28, 2027. Check the organizer's page for changes before booking.
Where can I find the ChangeNOW exhibitor list?
We have not linked a public exhibitor directory for this edition. Ask the organizer about current directories and attendee access.
Does a company listing confirm who will attend?
A sponsor, exhibitor or speaker listing establishes that published role. It does not establish which employees will attend or whether they are buying. Previous-edition examples remain historical.
How can Emitree help with ChangeNOW?
We research relevant accounts using public conference sources and any lists you provide. We qualify the accounts against your offer, run agreed outreach and record replies and meetings in your CRM.
