## Positions at a glance

### Supporters

The report carries particular weight for the Global South, including India, Pakistan, and Bangladesh, whose exposure to floods, cyclones, heatwaves, and sea-level rise makes adaptation existential rather than discretionary. Its findings shaped the COP27 (Sharm el-Sheikh, 2022) decision to create the Loss and Damage Fund, operationalised at COP28, and informed debates on doubling adaptation finance — a pledge developed countries made at Glasgow to scale up support from 2019 levels by 2025. As of 2026 the report continues to document that adaptation finance remains far below the doubling target and that the new collective quantified goal on finance, agreed at COP29 in Baku (2024), is widely seen as inadequate to the assessed need.

### Opponents

The report tracks three interlinked dimensions of the adaptation gap: finance, planning, and implementation. On finance, it estimates developing-country adaptation needs and compares them to actual international public flows, repeatedly finding a chasm of an order of magnitude — recent editions placed annual developing-country needs in the range of roughly US$215–387 billion through 2030, against flows that actually declined in some years. On planning, it counts how many of the world's nations have adopted a National Adaptation Plan (NAP), strategy, or law. On implementation, it assesses whether plans translate into projects on the ground, drawing on Adaptation Fund and Green Climate Fund disbursements. The 2022 edition was titled "Too Little, Too Slow" and the 2023 edition "Underfinanced. Underprepared," signalling UNEP's consistent verdict that the gap is widening rather than closing.

Example

In November 2023, UNEP released the Adaptation Gap Report titled "Underfinanced. Underprepared," days before COP28 in Dubai, estimating developing-country adaptation needs at US$215–387 billion annually through 2030.
