The Adaptation Financing: Climate Investment Planning and Mobilization Framework Supplement was published by the NDC Partnership, with contributions from the Adaptation Fund, Asian Development Bank (ADB), and the Commonwealth Secretariat, in October 2025. The supplement provides practical guidance for countries on how to move from adaptation planning to implementation by turning NAP and NDC priorities into financeable investment plans and bankable adaptation projects.
Key insights:
Developing countries need an estimated USD 2.3–2.5 trillion annually in adaptation investment to meet their 2030 climate goals, yet only USD 76 billion was invested globally in adaptation in 2022.
The report stresses the need to move from adaptation planning to real implementation through investment plans, financing strategies, institutional mechanisms, and bankable project pipelines.
Key barriers include limited private sector engagement, fragmented planning, complex funding requirements, weak institutional capacity, and limited technical expertise.
The supplement presents a roadmap for adaptation investment planning, including risk analysis, prioritization, financing, public investment management, and enabling policy reforms.
It emphasizes locally led adaptation, direct access to finance, knowledge sharing, innovation, and scaling up successful adaptation projects.
The report highlights the importance of building both human and institutional capacity to mobilize and manage adaptation finance.
It concludes that adaptation finance is not only about raising more money, but also about helping countries receive, allocate, and deploy finance effectively through stronger systems, coordination, and long-term financial sustainability.
