The report finds that urban adaptation finance is significantly underfunded, representing only 3-5% of total global adaptation flows, with an estimated annual investment of up to USD 3.7 billion against a projected need of USD 11-20 billion for urban infrastructure protection. Analysis of the Global Landscape of Climate Finance, World Bank PPI, and CDP Cities data reveals a heavy concentration of funding in the water and wastewater sectors and a geographic bias toward East Asia and the Pacific, particularly China. Key barriers to scaling finance include limited DFI mandates for sub-national investment, poor municipal creditworthiness, and a lack of standardized outcome metrics for private investors. The report recommends developing practitioner case study databases, improving urban boundary tracking, and expanding DFI mandates to work directly with cities.
