The C40 Cities Climate Leadership Group (C40) is a network of nearly 75 cities around the world that are taking measurable and scalable action to reduce their carbon emissions. C40 also partners with the Clinton Climate Initiative and the World Bank to 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—there is plenty of talk, but little action. 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.
To mobilize climate action among cities, the United Nations Secretary General Ban Ki-moon appointed Mike Bloomberg as the first U.N. Special Envoy for Cities and Climate Change in early 2014. 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 Climate Leadership Group, a network of large cities from around the world committed to implementing meaningful and sustainable climate-related actions.

DRIVING CLIMATE CHANGE AT THE LOCAL LEVEL
National governments have been seemingly incapable of taking coordinated international action on climate change. We cannot rely on them 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.
Working in partnership with the Clinton Climate Initiative, the World Bank and other partners, we have seen considerable progress in the speed and scale of our efforts.
