COP31’s everyday test: who gets protection when adaptation money falls short?

International public adaptation finance reaching least developed countries and small island developing states remained below its 2022 peak in 2024, according to UNEP’s Adaptation Gap Report 2026. Flows had grown in real terms since 2019, but that longer-term improvement did not prevent the retreat from the peak. A rising global total, in other words, does not necessarily mean more resources are reaching these countries.

That distinction should shape the conversation as COP31 opens. The summit is scheduled for November 9–20 in Antalya, Türkiye; Le Monde’s pre-summit briefing identifies indicators for measuring adaptation progress among its negotiating subjects. Those indicators may sound remote from everyday life. Their purpose should be anything but remote: to establish whether people are better protected when heat, flooding or water shortages interrupt the services and work on which they depend.

The question is not whether financial totals matter. It is whether those totals are being asked to tell a story they cannot tell alone.

A larger total can conceal an uneven distribution

UNEP puts international public adaptation finance from developed to developing countries at US$28.2–31.7 billion in 2024, approximately US$1 billion more than the previous year. This is a specific category of finance, not a total for all climate spending, domestic investment or private funding. Keeping that boundary clear matters when assessing announcements made under the much broader label of climate finance.

The contrast with flows to least developed countries and small island developing states is the central warning. An aggregate increase can coexist with a decline from an earlier peak for particular recipients. Neither observation cancels the other.

Nor do those country groupings describe interchangeable circumstances. Least developed country status and small island developing state status identify different characteristics and can overlap. An island’s coastal exposure does not describe every problem facing its residents; low national income does not reveal which districts have dependable water supplies or which workers can afford to stop working during dangerous heat.

Country-level allocation is therefore only the first distributional question. Within a funded programme, protection may depend on where infrastructure is built, who can connect to it, what users must pay and whether maintenance continues. These are questions to investigate—not outcomes that UNEP’s aggregate figures establish.

Why tripling finance could matter more in some countries

The report also offers a reason to resist fatalism. UNEP estimates developing-country adaptation needs at US$305 billion annually by 2035. Under its projections, tripling international public flows would cover 20–29% of overall needs. Tripling flows to least developed countries and small island states could cover a much larger share of their needs: 49–84%.

These are projected coverage ranges, not money delivered or protection achieved. They should not be read as a promise that every country in either grouping would receive the same proportion of what it needs.

Still, the contrast is important. The same language of “tripling” can describe markedly different relationships between available finance and estimated needs. A global funding gap can remain vast while targeted increases make a substantial difference for particular groups of countries. That is an argument for examining allocation alongside scale, not for abandoning either.

Carbon Brief’s COP31 negotiating tracker reports that the African group requested additional agenda items on tripling adaptation finance and funding for the Green Climate Fund. A request is not an adopted agenda item, much less a negotiated outcome. It does, however, put the relationship between ambition and funding firmly in view before the talks.

The distance between a pledge and a public service

A commitment announced at a summit is not yet a functioning water system. Between the two sit approval procedures, disbursements, procurement, construction and the less conspicuous work of keeping equipment operational.

The funding channel matters. Bilateral support, multilateral climate funds and development-bank finance should not be treated as identical routes merely because they contribute to a common headline. Reporting should show who administers funding, whether it is a grant or a loan, when recipients can use it and what obligations accompany it. A loan and a grant of equal face value do not have the same implications for a public budget.

Dependability matters too. A water authority needs to plan beyond an announcement cycle. A protective asset without provision for inspection, repairs and staffing can leave a gap between recorded expenditure and lasting service. These are practical reasons to track delivery over time rather than count a project once and move on.

The everyday consequences also differ. For a tenant, a housing adaptation programme raises questions about eligibility and continued affordability. For a farmer, useful support depends on local growing conditions and access to water or advice. For someone with limited mobility, an evacuation plan must include accessible transport and shelter. None of these needs can stand in for all the others.

Measure who is protected—and who is missing

COP31 adaptation finance needs a financial ledger and a service ledger. The first should distinguish pledges, approved funding and disbursements. The second should examine what that spending enables, for whom and for how long.

For water infrastructure, a useful measure could include service reliability during dry periods, not simply the number of installations completed. For flood protection, an assessment could examine which neighbourhoods benefit and whether risk is shifted elsewhere. Livelihood programmes could be judged partly by whether intended participants can actually access support.

These are proposed tests, not descriptions of indicators already agreed at COP31. They would also require resources. Demanding increasingly elaborate reporting from institutions without funding their capacity to collect and interpret data risks rewarding administrative strength rather than revealing unmet need.

Residents should have ways to challenge official accounts of success. Consultation cannot guarantee agreement: tenants, landowners, fishers and businesses may have conflicting priorities. But disagreement is information, not a reason to reduce a place to a single beneficiary count.

There is another boundary to preserve. Adaptation seeks to reduce climate risks and vulnerability; loss-and-damage funding addresses harms associated with climate impacts, including those not avoided. Support after damage is not evidence that preventive protection was delivered. Neither category should be used to obscure shortfalls in the other.

Before negotiations begin, there is no basis to approve COP31 as a success. Larger commitments would deserve scrutiny and, where warranted, recognition. The more demanding test comes afterward: whether funding arrives predictably, whether services endure, and whether people previously overlooked can demonstrate that protection now reaches them.
