On Thursday morning in Paris, the Organisation for Economic Co-operation and Development (OECD) published fresh figures indicating that developed countries have not fulfilled their commitment to double adaptation finance to $40 billion annually for vulnerable nations, a milestone originally targeted for last year. The shortfall comes as fiscal tightening and aid cuts continue to shape budget discussions in capitals across Europe, North America, and parts of East Asia this spring.
The 2026 release of adaptation finance data draws a sharp line under the pledge made at past global climate summits, where wealthy nations had promised to scale up support for climate resilience in the Global South. According to the OECD, actual disbursements in 2025 fell well below the $40 billion mark, with several large contributors reporting static or declining adaptation allocations. This under-delivery is especially significant as communities in Sub-Saharan Africa and Southeast Asia face early heatwaves and unpredictable rainfall patterns at the start of the planting season.
The $40 billion adaptation target, which was meant to be part of the broader $100 billion annual climate finance goal, has been a key metric for tracking progress on SDG 13 (Climate Action) and Paris Agreement implementation. So far in 2026, only a handful of countries—such as Denmark and Canada—have publicly detailed their adaptation funding breakdowns, while others, including the United States and Japan, have cited domestic budget pressures as reasons for falling short.
Civil society groups across Nairobi, Dhaka, and Lima responded on Wednesday with calls for greater transparency and accountability from donor governments. “These are not just numbers. They translate to lost crops, damaged infrastructure, and human displacement,” said Fatoumata Diarra, adaptation policy lead at the African Climate Foundation, during an SDG forum in Dakar. The OECD’s report further notes that a significant portion of what is counted as adaptation finance still arrives as loans rather than grants, challenging the spirit of the original commitment.
With the next ministerial-level UN climate meeting scheduled for late summer, adaptation finance delivery is expected to dominate the agenda. Analysts warn that unless major donors revise their 2026 budgets in the coming months, the adaptation funding gap may widen, undermining trust ahead of the next round of global climate negotiations.
