About

Mayors, governors, and business leaders first began signing the We Are Still In declaration in June 2017 as a promise to world leaders that Americans would not retreat from the global pact to reduce emissions and stem the causes of climate change. The bipartisan coalition has since doubled in size, expanding to include over 2,700 representatives from all 50 states, spanning large and small businesses, mayors and governors, university presidents, faith leaders, tribal leaders, and cultural institutions.

We Are Still In signatories represent a constituency of more than half of all Americans, and taken together, they represent $6.2 trillion, a bigger economy than any nation other than the U.S. or China.

We Are Still In is an effort coordinated by The American Sustainable Business Council, B Team, Bloomberg Philanthropies, Center for American Progress, Ceres, CDP, Climate Mayors, Climate Nexus, C40, C2ES, Environmental Defense Fund, Environmental Entrepreneurs, Georgetown Climate Center, ICLEI, National League of Cities, Rocky Mountain Institute, Second Nature, Sierra Club, Sustainable Museums, The Climate Group, We Mean Business, World Resources Institute (WRI), and World Wildlife Fund (WWF).

We Are Still In is a bottom-up network, supported by many individuals and organizations. “America’s Pledge” is a separate initiative spearheaded by Former New York Mayor and UN Special Envoy Michael Bloomberg and California Governor Jerry Brown, working in parallel with We Are Still In to compile and tally the climate actions of states, cities, colleges, businesses, and other local actors across the entire U.S. economy.
