Multilateral development banks increase climate finance to record $163 billion in 2025, supporting climate-resilient and sustainable growth

13 July 2026 — Multilateral development banks (MDBs) including the New Development Bank increased climate finance to record levels in 2025, reinforcing their role in supporting climate-resilient and sustainable economies. Climate finance by MDBs in low- and middle-income countries jumped 21% from the previous year to an all-time high of $103 billion while MDB climate finance across all countries of operation rose 19% to a record $163 billion.

The results, published today in the 2025 Joint Summary Report on Multilateral Development Banks’ Climate Finance, confirm that MDBs are on track to meet their 2030 projections announced at the United Nations climate conference COP29 in Baku in 2024.

In low- and middle-income economies, MDB climate finance has doubled over the past five years. Of the $103 billion amount in 2025, mitigation accounted for the largest share at $68 billion while adaptation finance continued to grow rapidly to $35 billion. Private-sector mobilisation in these countries reached $35 billion.

In high-income economies, MDB climate finance in 2025 also remained substantial, meeting or exceeding 2030 projections five years in advance and supporting primarily mitigation efforts with $53 billion, alongside adaptation investments of $7 billion. Private finance mobilisation in these countries reached $80 billion.
