Adaptation Finance Gap Leaves World Unready
A UN report finds tripled adaptation funding by 2035 would still cover only 20-29 per cent of developing countries' needs.

Should your national government increase spending on climate adaptation?
The United Nations Environment Programme released its Adaptation Gap Report 2026, concluding the world is not ready to adapt to current climate conditions. International public adaptation finance from developed to developing countries grew by US$1 billion between 2023 and 2024. This is a report-based assessment, not a new technology, and its findings are shipped policy data rather than a product.
Why it matters
The report measures adaptation progress against the Glasgow Climate Pact goal of roughly US$40 billion per year in flows by 2025, a target now being judged against actual funding. With global warming now set to exceed 1.5°C, the gap between finance flows and projected needs of about US$305 billion per year by 2035 is the central constraint on adaptation.
The report's adaptation finance figures are measured as international public flows from developed to developing countries, compared against the Glasgow Climate Pact doubling target of about US$40 billion per year by 2025. Tripling flows by 2035 would cover only 20-29 per cent of developing countries' finance needs after inflation adjustment.
The players
United Nations Environment Programme (UNEP)
The UN's environmental agency, which publishes the annual Adaptation Gap Report tracking the distance between climate adaptation needs and the finance that meets them.
Fund for responding to Loss and Damage
The international fund created to help vulnerable countries pay for climate-driven losses and damages, whose initial funding round envelope was US$342 million.
The details
Adaptation finance is money spent to reduce vulnerability to climate impacts such as floods, drought and heat, distinct from the funding that cuts greenhouse emissions. The report tracks public flows from wealthy to poorer nations and adds private-sector and developing-country-to-developing-country flows, which are growing. Governments are also strengthening the institutional structures that turn adaptation priorities into implemented projects, since a lack of finance remains the largest obstacle.
Timeline
2023 to 2024: International adaptation finance flows grew by US$1 billion.
2025: The Glasgow Climate Pact target of roughly US$40 billion per year in flows was due, and multilateral development banks increased adaptation financing significantly.
2035: Adaptation finance needs are projected to reach about US$305 billion per year.
The Tech Race
The adaptation-finance trajectory is being judged against the Glasgow Climate Pact doubling goal, which sets the benchmark for progress. The COP31 climate conference in Türkiye is the next forum where nations must intensify efforts to reach a tripling of adaptation finance by 2035.
Communities facing floods, drought and heat depend on adaptation projects that are funded only when public and private money reaches them, so the shortfall affects local resilience directly. Timing for specific national or project-level funding is not set out in the report, and the extraction does not give a date for when new finance will reach affected populations.
The takeaway
Watch whether adaptation finance can triple by 2035 as set out at COP31 in Türkiye, the next milestone against which the report's gap will be measured. The Glasgow doubling outcome for 2025 is a verifiable result still to be confirmed.
What happens next
Nations are due to intensify adaptation-finance efforts at the COP31 climate conference in Türkiye, where the tripling-by-2035 goal will be pressed.
