The C40 Cities Climate Leadership Group, now in its 11th year, connects more than 80 of the world’s greatest cities, representing 600+ million people and one quarter of the global economy. Created and led by cities, C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban citizens.

The current chair of C40 is Mayor of Paris, Anne Hidalgo; three-term Mayor of New York City Michael R. Bloomberg serves as President of the Board. C40’s work is made possible by our three strategic funders: Bloomberg Philanthropies, Children’s Investment Fund Foundation (CIFF), and Realdania. C40 was founded on the idea that cities can achieve more by working together than acting alone. C40’s international staff supports mayors of the world’s megacities to deliver bold, ambitious and transformational action on climate change, through the exchange of ideas, programmes and policies; world class research; technical expertise; events that convene the world’s foremost climate experts and communications support to highlight the individual achievements and collective leadership of cities. Member cities have already committed to reducing their emissions by a total of more than 3 gigatons of C02 by 2030 - the equivalent of taking 600 million cars off the road. C40 Initiatives and Networks.

Working across multiple sectors and issues, C40 convenes networks that provide a range of services in support of cities’ climate change efforts. C40 has 17 networks organised under 6 initiative areas covering the mitigation, adaptation and sustainability topics of highest priority to C40 cities and with the potential for the greatest climate impact. C40 is also positioning cities as a leading force for climate action around the world, defining and amplifying their call to national governments for greater support and autonomy in creating a sustainable future.

C40 networks help cities replicate, improve and accelerate climate action. These city-only working groups provide for honest knowledge exchange, enabling cities to tap into the global expertise of their peers as well as connect with technical partners. Through networks, cities find opportunities to undertake joint projects in areas of mutual interest and benefit. C40 networks also amplify individual city solutions by providing a global platform for showcasing city successes. The result is that cities' climate actions to reduce GHGs and climate risks are bolder, more impactful, implemented faster, at a lower cost and with less resources than if they were to go it alone. No other organisation facilitates such deep connections amongst city staff across 50+ countries, 20 time zones and 26 languages to accelerate local action with major global impact.
