The United States Climate Alliance (U.S. Climate Alliance) is a coalition of governors formed in 2017 who support greenhouse gas reduction policies in line with the 2015 Paris Climate Accord, both in their states and at the federal level. The group is a project of the United Nations Foundation, a private nonprofit formed with a ten-year, $1 billion pledge by media mogul Ted Turner in 1997 to support the activities of the United Nations. 1 2

While the alliance is officially bipartisan, as of October 2022 only three of its 24 gubernatorial members were Republicans. 3


The U.S. Climate Alliance is a multi-state coalition that is committed to reducing greenhouse gas emissions consistent with the goals of the Paris Agreement reached during the Obama administration but abandoned during the Trump administration. 4 The alliance is a project of the United Nations Foundation. 5

The governors of the 23 states and Puerto Rico tout that they represent more than half of the U.S. population and more than $11 trillion in U.S. GDP. The states also tout representing about 1.7 million renewable energy and energy efficiency jobs. 6

The alliance started after the Trump administration withdrew the United States from the Paris Agreement in 2017. The founding members of the U.S. Climate Alliance were then-New York Gov. Andrew Cuomo (D), Washington Gov. Jay Inslee (D), and then-California Gov. Jerry Brown (D). 7 A day later, the governors of Connecticut, Massachusetts, Vermont, Rhode Island, Oregon, and Hawaii agreed to maintain their states’ support of the Paris Agreement and joined the alliance. 8

Policy Goals

Member states and territories commit to implement policies that advance the goals of the Paris Agreement, aiming to reduce greenhouse gas emissions by at least 26-28 percent below 2005 levels by 2025; track and report progress to the global community when the world convenes to evaluate the Paris Agreement; and accelerate new and existing policies to reduce carbon emissions and promote environmentalist energy deployment at the state and federal level. 9

As of mid-2022, the alliance says that 22 members have renewable and clean energy standards for electricity; 18 members have 100 percent zero-carbon or carbon-neutral electricity goals; and 14 members have economy-wide net-zero emissions goals. 10

The U.S. Climate Alliance joined with the governments of Canada and Mexico in November 2017 to establish the North American Climate Leadership Dialogue. As part of the agenda, the states of Connecticut, Hawaii, and New York joined Canada and Mexico in the “Powering Past Coal Alliance,” to phase out existing and prevent building new coal power stations. The alliance also joined with Canada and Mexico for two other projects, Resources for the Future, and Climate Impact Lab, to share information and scientific research to reduce carbon emissions. 11
