Mayors National Climate Action Agenda, or Climate Mayors, is an association of United States mayors with the stated goal of reducing greenhouse gas emissions. Founded by Los Angeles mayor Eric Garcetti, former Houston mayor Annise Parker, and former Philadelphia mayor Michael Nutter, the group represents 435 cities and nearly 20% of the U.S. population.^[1][2][3]

Founded in 2014, the organization received one million dollars in start-up funding from the Clinton Global Initiative to support the founding mayors' efforts to organize cities in advance of the signing of the 2015 Paris Agreement.^[4]

The organization has stated its commitment to upholding the emissions goals of the Paris Agreement on climate change even if the United States withdraws from the agreement.^[5]
