NEW YORK — Mayors and senior city leaders from more than 35 G20 cities ratified a joint action communiqué concluding the Urban 20 (U20) Mayors Summit in New York, demanding direct access to international finance and expanded local powers to combat extreme weather and rising costs. Co-chaired by New York City Mayor Zohran Mamdani and Los Angeles Mayor Karen Bass, the three-day summit brought together civic leaders representing over 500 million residents and one-third of global GDP. The gathering was convened by C40 Cities and United Cities and Local Governments (UCLG) [cite: 1.1.2]. The ratified action plan centers on accelerating a clean and just energy transition, bolstering urban resilience against extreme heat, flooding, and wildfires, and securing direct eligibility for multilateral climate and housing funds without routing resources through national bureaucracies first. Key structural demands include formal seats in national climate and energy planning, reliable data feeds for public health and meteorological early warning systems, and local regulatory tools for housing stability and tenant protection [cite: 1.1.4]. New York Mayor Zohran Mamdani stated that local governments deliver material change when given proper resources, emphasizing that working families face severe economic and environmental pressures [cite: 1.1.4]. Los Angeles Mayor Karen Bass noted that the communiqué transforms shared regional hurdles into a coordinated global execution strategy [cite: 1.2.2]. Yvonne Aki-Sawyerr, Mayor of Freetown and Co-Chair of C40 Cities, highlighted that urban centers across Africa, Europe, Asia, and the Americas confront parallel strains from soaring energy volatility and climate-driven displacement. Ugur Ibrahim Altay, President of UCLG and Mayor of Konya, stressed that multilateral financial systems must trust and build capacity directly through local governments [cite: 1.1.4]. Kate Johnson, C40 Cities Director for North America, pointed to ongoing climate disruptions as proof that international mobilization must flow faster to municipal frontlines [cite: 1.2.4]. The agreement serves as the foundational city-led kickoff for Climate Week NYC, establishing a unified municipal counterweight ahead of broader national G20 economic deliberations.
