Climate change is the greatest challenge facing humanity. An incredible array of leaders and organisations has driven the issue up the public and political agenda and secured countless successes. We celebrate this. Yet we also know that far more is needed, and that time is against us. We still need a step change in action from governments, businesses, investors and other organisations if we are to secure the decisive action we need in the next decade. We believe we can generate the political and societal will to achieve a just, prosperous world in which leaders are compelled to take climate action at the necessary speed and scale, by improving the connections between the community of organisations active on climate change and mobilising new champions for our cause. We are committed to enabling organisations to work together in new ways, combining their power and skills to secure the action we need.
