Accelerating America’s Pledge
Going All-In to Build a Prosperous, Low-Carbon Economy for the United States

U.S. states, cities, and businesses are forging a powerful approach to climate action that builds support and implementation from the ground up. By setting their sights higher, these leaders are laying the foundation for a comprehensive national climate strategy.

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

Accelerating America’s Pledge, launched at the 2019 COP25 conference, is the most comprehensive assessment to date of how these real economy leaders are driving the U.S. toward a low-carbon future.

This report illuminates a pathway to a comprehensive and ambitious American climate strategy for 2030, using expanded bottom-up leadership as the foundation of a comprehensive “All-In” climate strategy. This comes at a time when nations around the world are considering how to strengthen their climate targets and raise global ambition.
