The U.S. Climate Alliance and Related Actions

This fact sheet describes the formation and goals of the United States Climate Alliance and other subnational efforts to uphold the 2016 Paris Agreement following the Trump Administration's decision to withdraw the United States from the accord.

• The United States Climate Alliance is a bipartisan group of 13 states and one U.S. territory that aims to reduce carbon dioxide emissions by 26-28 percent from 2005 levels by 2025. The Alliance also seeks to meet or exceed the U.S. Clean Power Plan's target of a 32 percent reduction of CO2 emissions by 2030, regardless of whether the federal government abandons the plan.
• Formed on June 1, 2017, by the governors of Washington, New York, and California, the Alliance represented 32.3 percent of the U.S. population (over 100 million people) and 37.7 percent of the U.S. GDP as of 2016. By July 11, 2017, the membership grew to 14 entities, including the territory of Puerto Rico.
• Various city-led and private sector initiatives have emerged to support the Paris Agreement. The Mayors National Climate Action Agenda (MNCAA), also known as Climate Mayors, 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.
• Other coordinated efforts include the Under2 MOU, where subnational governments aim for an 80- to 95-percent reduction in greenhouse gas emissions compared to 1990 levels by 2050. Furthermore, a coalition of 13 state attorneys general is suing the Trump Administration to prevent the elimination of vehicle emissions standards that would have doubled average fuel efficiency by 2025.
• Financial and international efforts to fill the gap left by the federal government include a $15 million donation by former New York City Mayor Michael Bloomberg to the UN Framework Convention on Climate Change (UNFCCC). Additionally, the UNFCCC's Non-State Actor Zone for Climate Action (NAZCA) portal has recorded commitments from 2,508 cities, 209 regions, 2,138 companies, 479 investors, and 238 civil society organizations globally.
