New, legally-informed resource gives mayors and local leaders a framework for shaping responsible development that addresses data center impacts on energy, water, and land while centering communities and creating transparency. The model law provides a menu of legal and regulatory approaches across four areas including: Siting and permitting, operational standards, transparency, and community benefits.

Climate Mayors latest report offers mayors and city leaders research-backed insights into how residents experience extreme heat and practical opportunities to make local heat response more visible, accessible, and actionable. Created in partnership with Switch 5 and Hazelwood Network, this research explores what residents experience during extreme heat, what prevents them from staying safe, and opportunities for mayors to communicate more clearly on how cities are creating resiliency.

New York Climate Week was an opportunity to uplift the work happening in cities across the country into a larger conversation as Climate Mayors gathered at the Historic Roosevelt House Public Policy Institute to trade solutions on energy affordability, resilient housing and the infrastructure our communities depend on. We didn’t just talk about climate action, we showed what it looks like in practice.

Mayor Daniel Rickenmann: "In today’s economy, many families are already stretched by their monthly energy bills. This fall, we decide whether the next 15 years ease that pressure or add to it — and we should do that while the plans are still on paper, not when the bill arrives."

“This administration continues to be out of touch with the needs of everyday Americans. With gas at nearly $4.50 a gallon, families need every tool we have to cut what they spend getting to work and school. This rollback hands them the opposite: higher fuel bills, dirtier air in our neighborhoods, and a U.S. auto industry falling further behind," says Wright.

The Climate Mayors Economy is strong—and its progress is measurable. In partnership with Greenline Insights, this first-of-its-kind study defines the Climate Mayors Economy as the collective GDP and fuel consumption of Climate Mayors member cities. The report finds that Climate Mayors members are growing their economies while reducing fossil fuel use, translating into household savings. Maintaining the pace of progress could save households $38.4 billion over the next decade.

Climate Mayors announced the winners of the Climate Mayors Stories of Impact Challenge at their annual Leadership Forum held during New York Climate Week, highlighting how cities across the country are delivering real, tangible climate solutions that lower costs, strengthen communities, and improve quality of life. The Stories of Impact Challenge is part of Climate Mayors’ broader effort to equip local leaders with tools to communicate authentically and effectively in today’s digital landscape.

New U.S. Climate Alliance and Climate Mayors partnership counters ongoing federal retreat, advances key climate solutions across America. As the U.S. federal government continues its retreat from global climate efforts, mayors and governors representing America’s top state- and city-led climate action coalitions — the Climate Mayors and U.S. Climate Alliance — came together today at Climate Week NYC to announce a new joint partnership that supercharges non-federal climate collaboration, demonstrating the strength and durability of American climate leadership.

"EPA has a responsibility to work alongside local leaders to protect Americans' health, not eliminate the safeguards that protect families from deadly toxins," said Climate Mayors Executive Director Kate Wright.  For communities near fossil fuel infrastructure or already coping with extreme weather, fewer safeguards mean greater risks over time, even if utilities gain short-term flexibility.

Climate Mayors issued the following statement in response to the EPA's repeal of its 2024 Carbon Pollution Standards for fossil fuel-fired power plants, who also issued a supplemental proposal to strip its own authority to regulate greenhouse gas emissions from the power sector.

Mayor Shenise Turner-Sloss: "As federal energy regulators convene stakeholders to try to hammer out an agreement on PJM governance reforms, there can be no mistake about one change we must see: making the grid operator start serving the public interest."
