Washington, DC
Delegation organized by America Is All In, U.S. Climate Alliance, and Climate Mayors will show the world the strength and impact of U.S. city and state-led climate leadership and action
November 9, 2026 – Today, Climate Mayors, the U.S. Climate Alliance and America Is All In announced a U.S. delegation of more than 120 state, local, and cross-sector leaders who will participate in the 31st U.N. Climate Change Conference (COP31) in Antalya, Türkiye, from November 9 to November 20.
The delegation, which includes U.S. governors, mayors, and other top city and state officials, will be led by America Is All In Chair Gina McCarthy, Governor Michelle Lujan Grisham of New Mexico, Mayor Vicki Veenker of Palo Alto, California, and Mayor Janet Cowell of Raleigh, North Carolina. Additional mayors joining the delegation include Aaron Brockett of Boulder, Colorado; Michael Cahill of Beverly, Massachusetts; Joe Ganim of Bridgeport, Connecticut; Roderick D. Hampton of Haynesville, Louisiana; Nadia Mohamed of St. Louis Park, Minnesota; and Martha Guerrero of West Sacramento, California.
The U.S. Climate Alliance will also be represented by senior state officials from California, Maryland, New York, North Carolina, and Wisconsin. Additional high-level state and local leaders, including other governors, are expected to confirm their participation in the days ahead.
Participating U.S. leaders will take part in key conversations and programming at the America Is All In Pavilion, the central venue highlighting U.S. subnational climate commitments. In Antalya, the delegation will reinforce its dedication to climate action and showcase local climate solutions that are lowering energy costs, growing jobs, and cutting dangerous pollution in American communities.
“Mayors are closest to the people we serve, and when Washington steps back, we step up,” said Vicki Veenker, Mayor of Palo Alto, California, and member of Climate Mayors. “Together, our cities are turning climate commitments into projects that improve people’s lives. Throughout the last decade, U.S. Climate Mayors have been taking bolder and more sustained action on climate. Mayors are delivering pragmatic climate solutions to lower people’s energy bills, protect residents, and prove that local action adds up to national progress. That is the power of collective action, and that is the message we are bringing to Antalya.”
“Cities in the U.S. are proving that climate action can strengthen our communities and our economies—and together with the international community we can take those solutions to scale,” said Janet Cowell, Mayor of Raleigh, North Carolina and member of Climate Mayors. “U.S. cities are finding innovative ways to make our infrastructure more resilient, and gatherings like COP provide mayors an opportunity to compare ideas with mayors from all over the world and seek out more predictable pathways to public and private capital, so cities can move from promising projects to lasting climate investments that help families save money, strengthen communities, and prepare us for a changing climate.”
“America Is All In is showing up in force at COP31 to let the world know that millions of Americans are still in,” said Gina McCarthy, Chair of America Is All In, former White House National Climate Advisor, and 13th U.S. Environmental Protection Agency (EPA) Administrator. “Mayors, governors, and cross-sector leaders are here to demonstrate the strength of U.S. subnational climate leadership and build partnerships and solutions that lower carbon emissions, reduce pollution, and improve people’s lives everywhere.”
“Our delegation is traveling to COP31 in force to make it clear to the world that states and cities across the U.S. are undaunted, undeterred, and stand ready to strengthen our global partnerships. It’s through this deep and sustained collaboration that we make life better for people — and confront this global challenge,” said Michelle Lujan Grisham, Governor of New Mexico. “From Albuquerque to Antalya, our communities are telling us that they want to breathe cleaner air, access more affordable clean energy and cars, and feel safer when the next climate disaster hits. It’s our responsibility to deliver.”
