People in the United States may seem divided, but when it comes to protecting the planet, 25 governors have joined forces to support the Paris Agreement on climate change.

Two years ago on June 1, 2017, when the Trump administration announced its intention to withdraw from the Paris Agreement, the governors of California, Washington, and New York stepped up to support the international agreement. Since then, the U.S. Climate Alliance has grown to represent 24 states and Puerto Rico. And it continues to gain members.

Despite representing a wide variety of people, places, and economies, governors in the alliance are united by the same mission: to show that states can lead to climate action while growing clean energy economies, improving public health, and building more resilient communities.

Currently, the U.S. Climate Alliance represents 55% of the U.S. population, 40% of U.S. greenhouse gas emissions, and an $11.7 trillion economy. If the alliance were a country, it would be the third-largest economy behind the U.S. and China.
