America’s Pledge

America’s Pledge, an initiative of former New York City Mayor Michael R. Bloomberg and California Governor Edmund G. Brown, Jr., works to analyze, catalyze, and showcase how climate action led by states, cities, and businesses are driving the United States together toward a low-carbon future. Rocky Mountain Institute has served as co-lead of the America’s Pledge research program.

WHAT IS THE AMERICA’S PLEDGE INITIATIVE? 

In July 2017, former New York City Mayor Michael R. Bloomberg and California Governor Jerry Brown launched the America’s Pledge initiative to aggregate and quantify the actions of states, cities and businesses, and other non-national actors in the United States to drive down their greenhouse gas emissions consistent with the goals of the Paris Agreement.

In November 2017, America’s Pledge published a robust survey of U.S. climate action led by U.S. governors, mayors, business leaders, and others. This Phase 1 report estimated that real economy actors representing more than half the U.S. economy—whose economic activity is equivalent to that of the third-largest country in the world—were actively engaged in fulfilling the Paris Agreement. The report, launched by Bloomberg and Brown at the UN Climate Conference in Bonn, played a key role in providing confidence to the international community about ongoing U.S. decarbonization efforts.

In September 2018, America's Pledge is unveiling the most comprehensive assessment to date of how U.S. states, cities, and businesses are implementing climate targets and delivering emissions reductions within their own jurisdictions and operations -- and how they have the power to can go even farther and drive the United States faster toward a low-carbon future.

WHY IT MATTERS 

The Paris Agreement was the culmination of nearly 30 years of efforts to devise a durable strategy for ratcheting down global greenhouse gas emissions at a pace that would avoid the most dangerous effects of climate change. Like other countries, the United States made a pledge to reduce its emissions, with a specific target of 26-28% by 2025. Implementing the vision of the Paris Agreement calls for broad, rapid, and significant engagement across all parts of society in order to reap the benefits of a low-carbon, climate-resilient future fueled by clean jobs and economic growth.

America’s Pledge is showcasing that in the U.S., states, cities, businesses, and others are embracing this future—helping drive better outcomes for their own citizens and business operations—despite a step back in leadership and commitment by the U.S. federal government.
