The 2025 Cities Climate Finance Leadership Alliance (CCFLA) Annual Assembly will bring together key stakeholders to address one of the most urgent challenges of our time: mobilizing climate finance for cities. As home to over half the world’s population and responsible for more than 80% of global GDP, cities are on the frontlines of the climate crisis—experiencing its impacts while holding enormous potential for change. With an estimated USD 29.4 trillion climate investment opportunity in emerging market cities by 2030, there is a clear need to channel significantly more finance toward sustainable urban solutions like green buildings, public transport, and renewable energy.

Despite this potential, current urban climate finance flows fall far short of what is needed to meet global climate goals. The 2025 Assembly will serve as a platform to advance actionable solutions for scaling urban climate finance and overcoming persistent barriers. By convening city leaders, financial institutions, and development partners, CCFLA aims to drive momentum toward equipping cities with the resources they need to lead a just, resilient, and sustainable climate transition.
