The U.S. Climate Alliance and Climate Mayors announced a new partnership at Climate Week NYC to coordinate climate action across states and cities. The Alliance comprises 24 governors representing roughly 60 percent of the U.S. economy and 55 percent of the population. Climate Mayors represents more than 350 mayors across 47 states.
The joint agreement includes commitments to accelerate clean energy deployment, reduce greenhouse gas emissions consistent with the Paris Agreement, build climate resilience, create jobs in clean energy fields, and maintain consistency in climate policy across changes in federal administration.
Since 2005, the Alliance's members have collectively reduced electricity sector emissions by 44 percent while quadrupling electricity generation from wind and solar. Over the same period, member economies grew 37 percent.
In Climate Mayors cities, fossil fuel consumption per person fell 3.5 percent between 2019 and 2024 even as populations grew 1.2 percent and economies expanded 11.3 percent. That shift resulted in $27.2 billion less fossil fuel spending over five years, saving residents an average of $1,000 per year.
The coalitions will collaborate on clean electricity and energy affordability, healthy buildings and communities, transportation decarbonization, climate resilience, and workforce development. They plan to advance their partnership at COP31 in Antalya, Türkiye, later this year.
