About the Bloomberg American Cities Climate Challenge

Recognizing that cities account for more than 70% of global carbon emissions, the Bloomberg American Cities Climate Challenge was formed with an investment of $70 million to enhance the work already being done by mayors across the U.S. and to support cities in the fight against climate change. The Bloomberg American Cities Climate Challenge aims to go beyond the theoretical and scale up high-impact urban climate solutions that are already proven to succeed – specifically, from the buildings and transportation sectors. World-class partners for the Bloomberg American Cities Climate Challenge will be led by the Natural Resources Defense Council and Delivery Associates. The Bloomberg American Cities Climate Challenge is part of Mike Bloomberg’s American Cities Initiative, a suite of more than $200 million in investments to strengthen city halls and advance critical policies.
