C40 Cities

C40 Cities

My list

C40 is a network of nearly 100 mayors of the world’s leading cities working to deliver the urgent action needed right now to confront the climate crisis and create a future where everyone, everywhere can thrive. Mayors of C40 cities are committed to using a science-based and people-focused approach to help the world limit global heating to 1.5°C 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.

At Smart City Expo World Congress, C40 is showcasing innovative approaches to climate action including Zero Emission Areas, 15-minute cities, 24/7 carbon-free energy and more.
