Driving climate action fast
Our mission is to drive climate action. Fast.
Our goal is a world of net zero carbon emissions by 2050, with greater prosperity for all.
We focus on systems with the highest emissions and where our networks - both governments and businesses - have the greatest opportunity to drive change.
For over twenty years, we've built large and influential networks, holding organisations accountable and turning their commitments into action. We share what we achieve together to show more organisations what they could do.

At COP31, we're bringing leaders together to overcome barriers to climate progress – from financing local climate projects to accelerating the switch to clean energy.
A key moment will be the Subnational Investment Forum on 9 November, hosted by the Under2 Coalition and partners.
Building on a year of investment dialogues, the Forum will connect senior government officials with investors and financial institutions to develop concrete initiatives that help states and regions unlock funding and deliver more for their communities.
