Jeddah, Kingdom of Saudi Arabia, 9 September 2025: Global climate finance by Multilateral Development Banks (MDBs) increased 10% last year, reaching a record $137 billion, with the majority directed to low- and middle-income economies. MDBs including the Islamic Development Bank (IsDB) announced the year-on-year increase in a report published today.

• New report shows climate finance by multilateral development banks rose 10% in 2024 compared with previous year.
• MDBs’ climate finance for low- and middle-income economies increased 14% to more than $85 billion.
• Mobilised private finance for climate investments worldwide jumped 33% in 2024.

In addition, private finance mobilised by MDBs for climate action reached $134 billion in 2024, a 33% increase from the previous year, according to the new report. The latest climate finance data from MDBs will inform preparations for the United Nations Climate Change Conference (COP30) in Belém, Brazil in November 2025.  Expanding climate finance will be a central theme at COP30. At the last summit, held in Baku, Azerbaijan, in November 2024, countries agreed to scale up support for developing countries to at least $1.3 trillion annually from public and private sources by 2035.

Commenting on the report, IsDB Vice President (Operations), Dr. Rami Ahmad, said, "The record US$137 billion in climate finance delivered by Multilateral Development Banks (MDBs) in 2024 demonstrates our shared commitment to addressing the devastating effects of climate change. At the Islamic Development Bank (IsDB), we are proud to have contributed to this milestone, surpassing our targets on climate action. Guided by our new 10-year Strategic Framework, our focus remains on supporting member countries to build resilience, safeguard livelihoods, and pursue sustainable development pathways."

Climate finance is central to the efforts of MDBs to advance sustainable development worldwide. By supporting investments in renewable energy, green cities, clean transport, water and food security, MDBs help countries move closer to achieving their sustainable development goals. 

Digital portal

This year, MDBs are advancing a digitalisation initiative aimed at improving transparency and making their joint climate finance data more accessible and user-friendly. They plan to present progress on this project at COP30. As part of the transition, the 2024 Joint MDB Climate Finance Report is being released as a summary infographic, highlighting key results for the year. Starting in the fourth quarter of 2025, detailed data will be available through an interactive web platform, giving stakeholders real-time access to climate finance information and enabling them to track MDBs’ collective progress towards their climate finance goals. 

Low- and middle-income economies

Last year, $85.1 billion of MDBs’ climate finance were for low- and middle-income economies. Climate finance in these countries has more than doubled over the past five years and increased 14% on the year. Of this sum, 69% – or $58.8 billion – went to climate change mitigation and $26.3 billion, or 31%, for climate change adaptation. The amount of mobilised private finance for climate investments in these countries stood at $33 billion.

High-income economies

In 2024, MDBs’ climate finance for high-income countries totaled $51.5 billion, of which $46.5 billion (90%) supported climate change mitigation and $5 billion (10%) supported adaptation. In addition, mobilised private finance for climate investments in high-income countries reached $101 billion.
