Background C40 is a network of nearly 100 mayors of the world’s leading cities, who are 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. C40’s team of 400 staff is based in offices in London, in New York, Johannesburg, Singapore, Delhi, Rio de Janeiro, Copenhagen, Beijing and Paris, and individual staff based across 25 different locations. The strategic direction of the organisation is determined by an elected Steering Committee of C40 mayors, which is chaired by Mayor Sadiq Khan of London and Mayor Yvonne Aki-Sawyerr of Freetown. Three-term Mayor of New York City Michael R. Bloomberg serves as President of the C40 Board of Directors, responsible for operational oversight. A regionally diverse management team, led by Executive Director Mark Watts, leads the day-to-day management of C40. C40’s three core strategic funders are Bloomberg Philanthropies, the Children’s Investment Fund Foundation and Realdania.
