Climate Mayors is a bipartisan network that brings together U.S. mayors to advance practical climate action in their communities. Founded in 2014, the coalition represents cities across 48 states and reflects local governments’ commitment to climate progress. The website describes a network of nearly 350 member mayors, while other supplied materials cite more than 750 mayors and differing population totals, so membership figures may vary across published content.

Rather than selling consumer products, Climate Mayors supports local leaders with programs, information, and opportunities to collaborate. Its resources cover electric vehicles, clean-energy tax credits, data centers, extreme heat, household affordability, public safety, water security, utility rates, and state preemption. Initiatives include the Stories of Impact Challenge, the Climate Mayors Ambassador Program, and tools such as the Direct Pay Tracker and Tax Credits Toolkit. The organization also shares city examples, research, events, communications materials, and working groups for members. Through its network, resources, and public advocacy, Climate Mayors helps mayors learn from one another and communicate how local climate solutions can support residents, public health, and community prosperity.
