The Power of C40 Cities

C40 cities have tremendous power to act on climate ambitions -- and their power only grows when they work together. 

C40 networks facilitate dialogue amongst city officials. This builds trusted relationships, which in turn ensures that ideas, solutions, lessons, questions, and even friendly competition can flow freely and responsively to cities' needs. Rather than end at a case study or report, 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. No other organisation facilitates such deep connections amongst city staff across 50+ countries, 20 time zones and 26 languages to accelerate local action with major global impact.

Each member city's participation in a topical group of C40 networks is represented below.
