Fulfilling America’s Pledge: How States, Cities and Businesses are Leading the United States to a Low-Carbon Future

Back to All Publications

Meeting the ambitious goals of the Paris Agreement demands full partnership and deep collaboration between all actors across our society: states, cities, businesses, universities, and communities.

The decisions taken by these real economy actors shape the trajectory of greenhouse gas emissions, drive innovation across the economy, and determine the speed of the global energy transition. And nowhere is this kind of decentralized climate leadership currently more important than in the United States.

The America’s Pledge initiative was established by former New York City Mayor and United Nations Special Envoy for Climate Action Michael R. Bloomberg and California Governor Edmund G. Brown, Jr. to aggregate, analyze, and showcase climate leadership by America’s states, cities and businesses.

Fulfilling America’s Pledge, launched at the 2018 Global Climate Action Summit, is the most comprehensive assessment to date of how these real economy leaders are driving the United States toward a low-carbon future.
