The C40 Cities Climate Leadership Group (C40) is a network of more than 90 cities around the world that are taking measurable and scalable action to reduce their carbon emissions and accelerate progress on combating the negative impacts of climate change.
Under Mike Bloomberg’s leadership, the C40 adopted a new emphasis on accountability by using outcome-driven performance metrics.
C40 embodies Bloomberg Philanthropies’ vision for tackling climate change: driving scalable and replicable actions at the city and local level.
Everyone is at risk from the impacts of climate change, and with no action, the world faces significant financial, public health, and safety consequences. For decades, federal governments and international bodies have been incapable of adequately tackling the problem. Now, however, the world’s cities have taken the lead in fighting the impacts of climate change locally, and their collective efforts are having a global impact.
Leveraging his three terms of Mayor of New York City, Mike Bloomberg served as the first U.N. Special Envoy for Cities and Climate Change since early 2014, before being named the U.N. Special Envoy for Climate Action in March 2018. In this role, Bloomberg is helping national governments set more ambitious climate targets by showing them how much cities can do to reduce emission and build resilience. Bloomberg also currently serves as the President of the Board of the C40 Cities Climate Leadership Group, a network of large cities from around the world committed to implementing meaningful and sustainable climate-related actions. Since 2015, Bloomberg has chaired the global Taskforce on Climate-related Financial Disclosures.
APPLYING THE BLOOMBERG PHILANTHROPIES APPROACH TO COMBAT CLIMATE CHANGE
DRIVING CLIMATE CHANGE AT THE LOCAL LEVEL
We cannot rely on national governments or international bodies to solve the climate problem. Change must start at the local level.
Whereas national governments—by their nature—are somewhat removed from citizens, city mayors on the other hand, are directly accountable to their constituents and are therefore able to take decisive actions that can yield immediate results. What our cities do individually and in unison to address climate change can set the agenda for communities and governments everywhere. Although there is no single solution for solving global climate change, cities have the ability, capacity, and will to lead.
C40 is making a significant difference in improving the scale and speed of local climate action. When C40 cities implement strategies, take action, and share knowledge, the collective impact is exponential.

WHILE OTHERS CONTINUE TO TALK, WE’RE MAKING REAL AND MEASURABLE PROGRESS RIGHT NOW
Our partnership with the C40 Cities Climate Leadership Group provides valuable resources to help mayors around the world execute their local sustainability objectives.
We know that climate mitigation efforts are not a one-sized-fits-all solution to reducing greenhouse gas emissions. Our approach supports city governments’ ability to tackle the challenges most relevant to their immediate and long-term needs.
THOUSANDS OF INDIVIDUAL ACTIONS ADD UP TO A SEA OF CHANGE
Today, more than 10,000 measurable climate change actions are in effect in the more than 90 C40 cities.
