State and Trends in Climate Adaptation Finance 2023

The report finds that while global climate finance reached USD 1.3 trillion in 2021–2022, adaptation finance is diminishing in relative importance, accounting for only 5% of total flows. Developing countries face a significant funding gap, needing approximately USD 212 billion annually by 2030. In Africa, adaptation finance grew modestly by 14% to USD 13 billion annually, yet remains far below the estimated need of USD 53 billion per year. The analysis highlights an over-reliance on debt as the primary financial instrument and a critical lack of robust, adaptation-specific commitments from public financial institutions. Furthermore, it reveals a disconnect between adaptation finance and humanitarian aid, noting that the most fragile African states depend on emergency response funding because they struggle to access proactive adaptation finance.

• Global adaptation finance is decreasing as a proportion of total climate finance, falling from 7% in 2019–2020 to 5% in 2021–2022, despite an absolute increase to USD 63 billion annually.
• There is a severe adaptation funding gap in developing countries, which require between USD 130–415 billion per year by 2030, while only USD 56 billion was tracked in 2021–2022.
• Africa received USD 13 billion in adaptation finance in 2021–2022, representing 20% of global flows, but this is insufficient compared to the estimated annual need of USD 53 billion (2.5% of GDP).
• Private sector contribution to adaptation remains extremely low, consistently financing less than 3% of adaptation activities globally and in Africa from 2019–2022.
• Debt is the dominant financial instrument for adaptation, increasing from 70% of flows in 2019–2020 to 80% in 2021–2022, which poses risks to countries already facing debt distress.
• Public financial institutions generally lack robust adaptation commitments; of 60 institutions reviewed, only 13 had public adaptation-specific commitments.
• Adaptation finance in Africa is highly concentrated, with 54% of flows going to only 10 countries, while the bottom 10 recipient countries receive only 1%.
• There is a significant lack of coordination between adaptation finance and humanitarian aid; only 1.4% of international emergency response funding (USD 1.3 billion) was tagged as adaptation finance between 2019–2021.
• The most fragile African countries are heavily dependent on emergency response funding because they struggle to meet the enabling conditions required to access international adaptation finance.
• Post-disaster reconstruction funding has a higher overlap with adaptation than emergency funding, with 8% of international reconstruction funding counted as adaptation finance between 2019–2021.
