Climate change impacts are intensifying, yet financing for climate adaptation remains critically insufficient, particularly in developing countries. According to UNEP 2025 Adaptation Gap Report, developing countries will require an estimated USD 310–365 billion annually for climate adaptation by 2035, while current international public finance amounts to only around USD 26 billion per year, leaving a gap of USD 284–339 billion that places lives, livelihoods, and economies at severe risk.
75 countries have developed NAPs; it is now important to develop financing strategies to meet the targets set out in these plans. UNDP has developed the Adaptation Finance Strategy Guideline (AFSG), a practical framework for governments to mobilize and align finance for adaptation investments identified in National Adaptation Plans (NAPs) and Nationally Determined Contributions (NDCs).
The AFSG was developed by UNDP’s Adaptation team and the Climate Finance Network, with support from the the UK government’s flagship Climate Action for a Resilient Asia (CARA) programme, and the Government of Sweden through Sida.
The AFSG outlines a modular approach that enables governments, development partners and the private sector to collaborate effectively at national, sub-national or sectoral levels, based on different capacities and contexts on both the demand and supply sides of adaptation finance.
This webinar presents the AFSG and illustrates how it draws on country experiences, proven business models and financing approaches to strengthen systems, align financing with national adaptation priorities and scale up investment together with other partners.
