Mayors of C40 cities are committed to using a science-based and people-focused approach to limit global heating in line with the Paris Agreement and build healthy, equitable, and resilient communities. Through a Global Green New Deal, mayors are working alongside a broad coalition of representatives from labour, business, the youth climate movement and civil society to go further and faster than ever before. 

The current co-chairs of C40 are Mayor of London Sadiq Khan and Mayor of Freetown Yvonne Aki-Sawyerr. Three-term Mayor of New York City Michael R. Bloomberg serves as President of the Board. C40’s work is made possible by our strategic funders: Bloomberg Philanthropies and Realdania.
