The Climate Group

What The Climate Group does

The Climate Group is an international non-profit organization founded in 2004 and headquartered in London, operating as a convener of climate action networks across businesses, subnational governments, and civil society. The organization works with 650+ businesses and nearly 200 subnational governments across 35 countries through a portfolio of interconnected initiatives including RE100 (renewable energy commitments), EV100 and EV100+ (electric vehicle fleet transitions), EP100 (energy efficiency), SteelZero and ConcreteZero (low-carbon materials), 24/7 Carbon-Free Coalition, and the Under2 Coalition for subnational governments. The Climate Group does not develop proprietary technology products; its core function is network facilitation, peer accountability, and convening — operating flagship events like Climate Week NYC and the new Opportunity Summit in London, and maintaining a members-only Climate Group Hub portal. The organization is governed as The Climate Change Organisation, registered as a charity in England and Wales (charity number 1102909) and as a 501(c)(3) in the United States (The Climate Group, Inc, EIN 43-2073566), with operational teams in London, New York, New Delhi, Beijing, Amsterdam, Tokyo, and São Paulo.

The business model is non-profit and membership-based, generating revenue through membership fees, corporate sponsorships, philanthropic grants from foundations and development donors, and event-related income. The organization does not publicly disclose specific membership tier pricing or sponsorship packages. Its go-to-market approach is community-led: building large networks of committed organizations, holding them accountable to their climate pledges, sharing achievements to demonstrate what's possible, and using high-profile convenings to recruit new members and shape policy. The organization is a member of the We Mean Business Coalition and operates the secretariat for the Under2 Coalition. CEO Helen Clarkson has led the organization since 2017, supported by a management team that includes regional executive directors for North America, India, China, and Europe, and functional leads across communications, policy, energy, transport, philanthropy, and operations.

Highly comparable as a nonprofit that operates at the intersection of corporate accountability and environmental data on climate.
