Context:

Recently, United Nations Environment Programme (UNEP) published Adaptation Gap Report 2025 which underscores the growing shortfall in finance available to help developing countries adapt to climate change — even as climate impacts intensify.

Key Findings of the Report:

The report estimates that developing countries will need US$310–365 billion per year by 2035 for climate adaptation — based on modelled costs and extrapolations of National Adaptation Plans (NAPs).

• • By contrast, international public adaptation finance flows to developing countries in 2023 were only US$26 billion, down from US$28 billion the previous year. Hence, current flows are about 12–14 times lower than the estimated need.
  •  The report also warns that adaptation finance is heavily skewed toward loans (raising debt burdens) and private finance for adaptation remains very small (only a few billion currently).
  •  The report warns that the Glasgow Climate Pact goal of doubling adaptation finance to US$40 billion by 2025 will not be met if current trends persist.
  •  Even the New Collective Quantified Goal (NCQG) of US$300 billion per year for climate action by 2035, agreed at COP29 in Baku, will be insufficient, as it covers both mitigation and adaptation.

Implications for Developing Countries:

With adaptation finance falling far short of needs, developing countries remain exposed to infrastructural damage, crop losses, water stress, sea‑level rise, and extreme weather events.

·        Progress on poverty reduction, health, food security and infrastructure can be reversed if climate shocks strike and adaptation capacity is weak.

·        Since a large share of adaptation finance is in the form of loans (often non‑concessional), developing countries risk increasing their indebtedness while trying to build resilience.

·        Many developing nations contribute minimally to global greenhouse gas emissions but bear the brunt of climate impacts and face the largest adaptation burden.

Policy Recommendations from UNEP:

1.       Close the Finance Gap:
Mobilize new sources of public and private finance without increasing debt burdens.

2.      Enhance Global Cooperation:
Implement the Baku to Belém Roadmap adopted at COP29, ensuring equity and transparency in finance flows.

3.      Strengthen Mitigation Efforts:
Reduce future adaptation costs by curbing global warming through faster emission cuts.

4.     Promote Grants and Non-Debt Instruments:
Prioritize grant-based funding and debt relief for climate-vulnerable nations.

5.     Update and Mainstream Adaptation Plans:
Encourage countries to regularly revise National Adaptation Plans (NAPs) and integrate resilience into national development frameworks.

Conclusion:

The UNEP Adaptation Gap Report 2025 serves as a stark warning: the world is running out of time and resources to shield vulnerable nations from the escalating impacts of climate change. Without a rapid scaling-up of adaptation finance and equitable burden-sharing, the global community risks deepening inequality and reversing progress on sustainable development.
