The U.S. Climate Alliance and Related Actions

The United States Climate Alliance, formed on June 1, 2017, is a bipartisan group of 13 states and one territory committed to reducing carbon dioxide emissions by 26-28 percent from 2005 levels by 2025. This effort is part of a broader movement including the Mayors National Climate Action Agenda, the "We Are Still In" coalition, and the Under2 MOU, all aimed at filling the policy void created by the Trump Administration's withdrawal from the Paris Agreement. These subnational actors seek to maintain targets such as keeping global warming below 2 degrees Celsius and achieving 100 percent renewable power in some cities, though they face challenges regarding funding and the lack of a federal mandate.

• The United States Climate Alliance consists of 13 states and one U.S. territory, representing 32.3 percent of the U.S. population and 37.7 percent of its GDP as of 2016. The group aims to reduce carbon dioxide emissions by 26-28 percent from 2005 levels by 2025 and meet or exceed the U.S. Clean Power Plan's target of a 32 percent reduction by 2030.
• Various city-led and private sector initiatives have emerged to support the Paris Agreement, including the Mayors National Climate Action Agenda (MNCAA), which represents 359 U.S. cities and 66 million Americans. Additionally, the "We Are Still In" coalition includes signatories from 245 cities and counties, nine states, 324 colleges and universities, and 1,709 businesses and investors, representing 120 million Americans and $6.2 trillion in economic contributions.
• Subnational actors are pursuing specific policy and financial actions to replace federal commitments, such as the U.S. Conference of Mayors passing a resolution for 100 percent renewable power over the next decade and former Mayor Michael Bloomberg donating $15 million to the UNFCCC. Some states are also considering legislation to allow taxpayers to send tax rebates to the Green Climate Fund.
• The document notes that without federal mandates or funding, subnational entities may lack the resources to follow through on pledges and will likely vary in how they implement and enforce their climate actions.
