Developing countries need $305 billion yearly for climate adaptation
Poorer countries lack money for basic protection against worsening climate hazards.
Overview
Developing countries will need about $305 billion a year by 2035 to protect people from heatwaves, floods, droughts, wildfires and other climate dangers. In 2024, for this work was only $28.2 billion to $31.7 billion, about $1 billion more than in 2023. The money supports flood defenses, drought planning, heat protection and stronger buildings and services. Cutting emissions is separate.
Rich countries promised to double this funding from 2019 levels by 2025, but it is unclear whether they will meet that goal. A of $300 billion a year by 2035 covers both protection and emissions cuts. called for adaptation funding to triple. Together, these amounts would cover only about 20% to 29% of projected needs. Grants are limited, many countries already carry heavy debt, public bodies are weak and private investors are hard to attract. As a result, poorer countries delay protection while climate damage grows.
Timeline
UNEP estimated that developing countries need $305 billion annually for adaptation by 2035
UNEP's found that reached only $28.2 billion to $31.7 billion in 2024, roughly $1 billion more than the previous year. Developing countries need about $305 billion annually by 2035 for adaptation, covering measures such as flood protection, drought resilience, heat safeguards, wildfire preparedness and resilient infrastructure. Even tripling current flows to an estimated $85 billion to $120 billion would cover only about 20% to 29% of total needs, leaving vulnerable countries exposed to rising losses, damage and delayed action.
COP30 called for international adaptation finance to triple by 2035
adopted a call to triple international adaptation finance for developing countries by 2035, responding to escalating climate risks and pressure to turn earlier promises into a more specific adaptation target. The commitment was framed as an aspiration rather than funding that had already been delivered. Its practical effect depended on increased grants and , stronger institutions and faster implementation of delayed adaptation projects.
COP29 agreed to provide at least $300 billion annually in climate finance to developing countries by 2035
Countries at agreed on a new climate-finance goal of at least $300 billion annually for developing countries by 2035 and called for efforts to scale finance from public and private sources toward $1.3 trillion per year. The goal covers climate action broadly, including mitigation and adaptation, rather than guaranteeing a specific adaptation allocation.
UNEP estimated that developing countries needed up to $387 billion a year for adaptation
's 2023 estimated developing countries' adaptation needs at $215 billion to $387 billion annually during this decade. International public adaptation finance was far lower, producing an estimated gap of $194 billion to $366 billion per year. linked the shortfall to worsening floods, droughts, heatwaves and other climate impacts, as well as limited grants, debt burdens and barriers to implementing adaptation plans.
The Glasgow Climate Pact committed developed countries to double adaptation finance by 2025
At , developed countries agreed to at least double their collective adaptation finance for developing countries from 2019 levels by 2025. The benchmark was intended to correct the longstanding imbalance between mitigation funding and support for protecting communities from climate impacts. Later finance data showed that available flows remained below the implied target of about $40 billion annually.
Countries adopted the Paris Agreement and made adaptation a core climate priority
The established a global goal of enhancing adaptive capacity, strengthening resilience and reducing vulnerability to climate change. It also called for developed countries to provide financial resources for in developing countries, while recognizing that is distinct from , which cuts greenhouse-gas emissions. finance supports measures such as flood defenses, drought planning, heat protection and resilient infrastructure.
