The Power of C40 Cities

Each year, C40 surveys the Mayoral Powers of its member cities in order to understand where the greatest opportunities exist to advance specific climate actions and foster targetted knowledge sharing. The chart below reflects a summary of current Mayoral Powers by area, each of which is served by a C40 Initiative and its topical Networks. Cities whose mayors possessed strong or partial power over two-thirds of surveyed assets and functions in each category are indicated below. Cities who identified a climate action plan to C40 are also indicated in the Measurement and Planning category.
