C40 is a network of the world’s megacities committed to addressing climate change. C40 supports cities to collaborate effectively, share knowledge and drive meaningful, measurable and sustainable action on climate change.
C40 Networks create conversations, which enable cities to tailor their own actions to their unique situations, and band together to use their collective power to access partnership resources, including technical and financial support. The result is that cities' climate actions to reduce GHGs and climate risks are bolder, more impactful, implemented faster, at a lower cost and with less resources than if they were to go it alone.
