Climate Group
The Climate Group is an international non-profit organization founded in 2003 and officially launched in 2004 as a UK-registered charity dedicated to accelerating climate action through voluntary commitments from businesses and subnational governments toward net zero carbon emissions by 2050.[1]
Headquartered in London with offices in New York, New Delhi, Amsterdam, and Beijing, it mobilizes over 500 member organizations across 175 markets, focusing on high-impact sectors such as power, transport, industry, and food systems.[1][2]
Key initiatives include RE100, which unites influential companies committed to sourcing 100% renewable electricity; the Under2 Coalition, the world's largest network of 183 governments and regions pledging net zero emissions by 2050 at the latest; and sector-specific programs like EV100 for electric mobility and SteelZero for low-carbon steel production.[1][2]
The organization hosts prominent events such as Climate Week NYC, fostering collaboration among global leaders, and receives philanthropic funding from donors including the MacArthur Foundation and Bloomberg Philanthropies to support its operations.[1][2]
While its efforts emphasize corporate leadership and policy influence over direct emissions reductions, independent evaluations of the tangible causal impact of such voluntary coalitions on global greenhouse gas trajectories remain limited.[2]
