Company Overview

The C40 Cities Climate Leadership Group, now in its 12th year, connects more than 90 of the world’s greatest cities which have committed to tackling climate change. We bring mayors from around the world together to learn from each other in reducing greenhouse gas emissions and creating resilient, sustainable and low carbon cities. C40 cities represent more than 650 million urban citizens and their economies account for 25% of global GDP. Our recent ‘Deadline 2020’ report sets out the critical role that the world’s major cities have to play in delivering the historic Paris Agreement to prevent catastrophic climate change.

C40’s growing team of 100+ staff is headquartered in London, with offices in New York, Rio de Janeiro, Copenhagen, Beijing and Paris, and individual staff based across 25+ different locations. C40 has an operating budget of c.$25m per year and is primarily funded through the generous support of philanthropic foundations.

The strategic direction of the organization is determined by an elected Steering Committee of C40 mayors, which is chaired by the Mayor of Paris, Anne Hidalgo. Three-term Mayor of New York City Michael R. Bloomberg serves as President of the Board of Directors, which is responsible for operational oversight. A seven person management team, led by Executive Director, Mark Watts, leads the day-to-day management of C40.
