On October 29, the UN Environment Programme released the Adaptation Gap Report 2025, aptly titled “Running on Empty.” This report highlights a pressing issue: the world is striving for climate resilience but lacks sufficient funding.
Countries are experiencing more frequent climate disasters—like heatwaves, wildfires, and floods. These incidents come with heavy costs for recovery and adaptation, especially for vulnerable nations. While these countries are impacted the most, action to cut greenhouse gas emissions is still slow. This delay exacerbates the situation, putting additional pressure on poorer nations that can least afford it.
Inger Anderson, the Executive Director of UNEP, pointed out the responsibilities of developed nations. She noted they are aware they must support developing countries that contribute least to the climate crisis but suffer the most. According to the Paris Agreement and the Glasgow Climate Pact, developed nations pledged to fund adaptation efforts by contributing $40 billion annually by 2025.
However, at COP 29, the collective goal set for climate finance only reached $300 billion per year by 2035, falling short of the $1.3 trillion needed by developing countries. Recent statistics indicate that international public adaptation financing dropped from $28 billion in 2022 to $26 billion in 2023, highlighting a growing gap.
Experts estimate that developing countries will need between $310 billion and $365 billion per year for adaptation by 2035. Current aid flows are insufficient, emphasizing the importance of adequate financing. The needs are staggering: adapting to climate change will require at least 12 times the current funding levels.
While many countries are creating adaptation plans—172 out of 192 have one in place—many of these plans are outdated. For instance, 36 countries have not updated their strategies for over a decade. Immediate action is required to ensure these plans are not just on paper but are effectively implemented.
Though some reports suggest a slightly better situation for Least Developed Countries (LDCs) and Small Island Developing States (SIDs), funding levels still fall short. The recent conference outcomes at COP 29 indicate that the financial commitments are not keeping pace with inflation. Adjusted for a standard inflation rate of 3%, adaptation needs could rise to as much as $520 billion by 2035.
The report also discusses the potential role of the private sector in bridging the finance gap. Currently, private investments are low, with only around $5 billion annually reaching developing nations. However, experts suggest that with the right policies, this could increase to about $50 billion per year.
Looking ahead to COP 30 in Belem, Brazil, there are hopes that discussions will focus on equitable solutions for financing. For vulnerable nations, this means securing adequate budget allocations and ensuring local involvement in decision-making.
Addressing climate change isn’t just an environmental issue; it has significant implications for economies and livelihoods. Investing now in adaptation can reduce loss of life and protect infrastructure from severe climate impacts. The message is clear: countries must act swiftly to implement their adaptation plans and ensure financial support reaches those who need it most.
