UNEP Warns of Expanding Climate Adaptation Finance Gap Ahead of COP30

Climate Adaptation Funding Faces Massive Gap,UN Report Warns

Published: October 31,2025 03:40 am IST

The World is facing a stark reality: current efforts to protect vulnerable populations from the worsening effects of Climate Change are severely underfunded,according to a new assessment released by the United Nations Habitat Program. The report, titled Adaptation Gap Report 2025: Running on Empty, arrives ahead of the pivotal COP30 climate summit slated for Belém, Brazil.

Adaptation Finance Shortfall

The assessment finds that developing countries will require between $310 billion and $365 billion annually by the year 2035 to effectively adapt to the growing challenges posed by climate change.However, current international public adaptation finance stands at a mere $26 billion – a gap 12 to 14 times larger than the support currently available. This massive disparity threatens to derail progress and leave millions increasingly vulnerable.

Concerns are rising that the pledge made at the Glasgow Climate Pact to double adaptation finance to $40 billion by 2025 will not be met without a meaningful and immediate increase in funding commitments.

Global Leaders Sound the Alarm

UN Secretary-General António Guterres delivered a strong message, stating, “Climate impacts are accelerating. Yet adaptation finance is not keeping pace, leaving the world’s most vulnerable exposed to rising seas, deadly storms, and searing heat. Adaptation is not a cost – it is a lifeline. Closing the adaptation gap is how we protect lives, deliver climate justice, and build a safer, more enduring world. Let us not waste another moment.”

Inger Andersen, UNEP Executive Director, added, “Every person on this planet is living with the impacts of climate change: wildfires, heatwaves, desertification, floods, rising costs and more. As action to cut greenhouse gas emissions continues to lag, these impacts will only get worse, harming more people and causing significant economic damage. We need a global push to increase adaptation finance – from both public and private sources – without adding to the debt burdens of vulnerable nations. Even amid tight budgets and competing priorities, the reality is simple: if we do not invest in adaptation now, we will face escalating costs every year.”

Progress & Concerns

While 172 countries now have national adaptation policies, strategies, or plans in place, the report highlights a critical issue: 36 of these plans are outdated, increasing the risk of maladaptation-actions that could inadvertently worsen the situation. Countries have reported over 1,600 adaptation actions across sectors like biodiversity, agriculture, water, and infrastructure, though, consistent tracking and reporting of results remain limited.

Climate Funds, including the Adaptation Fund, the Global Environment Facility, and the Green Climate Fund, increased support to $920 million in 2024-an 86% increase from the previous five-year average. However, UNEP cautions that this surge may prove temporary, as emerging financial constraints could jeopardize future funding.

The New Collective Quantified Goal (NCQG), established at COP29 in Baku, aims for $300 billion per year by 2035 for climate action in developing countries.The report points out that, even this target, when adjusted for inflation, may prove insufficient, potentially increasing adaptation needs to $440-520 billion annually by 2035.

india’s Vulnerability

India is identified among countries facing heightened health risks from climate change. Harshal Salve, Additional Professor at AIIMS Delhi, explained, “Developing countries like India are experiencing increasing heat stress, water scarcity, wet bulb temperatures and air pollution amid climate change, which are adding to the health challenges in our regions. These threats are not only increasing coping pressure on local governance, hospitals and the health infrastructure but also require adequate finance for the scale of the problem. Real adaptation finance for health systems remains abysmally inadequate and in a post-pandemic world, this is not just an economic issue but a serious public health emergency in the making.”

Climate activist Harjeet Singh, Founding Director of Satat Sampada Climate Foundation, firmly stated, “This report confirms a staggering betrayal. The adaptation finance gap is a death sentence for communities on the frontline. For decades, the developing world has been told to prepare for a crisis they didn’t cause. They have done their homework-172 countries now have adaptation plans-but rich nations have offered only lip service, with finance flows decreasing last year. This monumental gap-now at least 12 times what is provided-is the direct cause of lost lives, destroyed homes, and shattered livelihoods. This is a deliberate political choice by rich countries to abandon the developing world to climate impacts they had no role in causing. It is the very definition of climate injustice.”

Dr. Jemilah mahmood, Executive director of the Sunway Centre for Planetary Health, emphasized, “The Adaptation Gap Report makes it painfully clear: we are dangerously underinvesting in climate resilience. The finance gap is not just a number; it’s a reflection of the growing risks to people’s health, safety, and dignity.”

Esther Penunia, Secretary-general of the Asian Farmers’ Association, argued, “New research shows that small-scale family farmers need an annual average investment of $952 for a one hectare farm – the equivalent of $2.19 a day – to adapt to climate change. Since we produce half the world’s food calories, surely this is a no brainer investment.”

Metric	Current Status (2025)	Needs by 2035
Annual Adaptation Finance Needed (Developing Countries)	$26 Billion	$310 – $520 Billion
Glasgow Pact Goal (2025)	Falling Short	$40 Billion
NCQG Target (2035)	Insufficient	$300 Billion (minimum)

The report suggests private sector investment could reach $50 billion annually with supportive policies and blended finance models, up from the current $5 billion.

Did You Know? Climate change adaptation isn’t just about large-scale infrastructure projects. It also includes simpler, community-based solutions like restoring mangrove forests for coastal protection or promoting drought-resistant crops.

Pro Tip: Individuals can contribute to climate adaptation by supporting local initiatives, advocating for climate-conscious policies, and making sustainable choices in their daily lives.

What specific actions can developing nations take to overcome barriers in accessing existing climate adaptation funds?

The Growing Divide: adaptation Finance Needs vs. Reality

The United Nations Environment Program (UNEP) has issued a stark warning: the gap between the financial resources available for climate adaptation and those actually needed is widening, posing a significant threat to vulnerable nations as COP30 approaches. This isn’t simply a matter of insufficient funds; it’s a systemic issue impacting the ability of developing countries to build resilience against the escalating impacts of climate change. Current estimates suggest adaptation needs are between $197 – $366 billion per year this decade, yet actual flows remain considerably lower. This shortfall jeopardizes progress towards the Global goal on Adaptation (GGA), a key pillar of the Paris Agreement.

Understanding the Adaptation Finance Gap

The adaptation finance gap isn’t a single number, but a complex interplay of factors. Here’s a breakdown of the key contributors:

* Underreporting: A significant portion of existing climate finance is reported as contributing to both mitigation and adaptation, inflating reported adaptation figures. UNEP’s research highlights the need for clearer definitions and more accurate tracking of adaptation finance.

* Access Barriers: Developing countries face substantial hurdles in accessing available funds. Complex request processes, stringent eligibility criteria, and a lack of capacity within national institutions all contribute to this challenge.

* Grant vs. Loan Imbalance: A large proportion of adaptation finance is provided as loans, increasing the debt burden on vulnerable nations already struggling wiht economic pressures. The need for increased climate grants is paramount.

* Private Sector Engagement: Mobilizing private sector investment in adaptation remains a major challenge. De-risking mechanisms and innovative financing models are crucial to attract private capital.

* Loss and Damage Funding: While the establishment of a loss and damage fund at COP27 was a landmark achievement, operationalizing it and ensuring sufficient funding remains a critical priority.

Key Findings from the UNEP Adaptation Gap Report 2025

The latest UNEP Adaptation Gap Report (2025) reveals several concerning trends:

* Adaptation finance flows in 2023 reached $119 billion, a slight increase from previous years, but still far below the estimated needs.

* West Asia and North Africa are the least adapted regions,facing the most significant challenges in securing adaptation finance.

* Ecosystem-based adaptation (EbA), a cost-effective and lasting approach, remains significantly underfunded despite its proven benefits.

* Early warning systems, crucial for reducing disaster risk, require substantial investment to ensure effective coverage and community-level implementation.

* Agricultural adaptation is critical for food security, yet receives insufficient funding, particularly in Sub-Saharan Africa.

Implications for COP30 in Brazil

COP30, hosted in Belém, Brazil, presents a crucial possibility to address the escalating adaptation finance gap. Key areas of focus should include:

1. Increased Pledges: Developed countries must significantly increase their commitments to provide adaptation finance, fulfilling the pledge of $100 billion per year.
2. finance Accessibility: Streamlining access to funds for developing countries is essential.This includes simplifying application processes, providing capacity-building support, and prioritizing grant-based financing.
3. GGA Framework: Operationalizing the Global Goal on Adaptation requires a robust monitoring and evaluation framework to track progress and identify areas for improvement.
4. Private Sector Mobilization: Innovative financing mechanisms,such as blended finance and risk insurance,are needed to unlock private sector investment in adaptation.
5. Loss and Damage Fund Operationalization: ensuring the effective and equitable distribution of funds from the loss and damage fund is critical for supporting countries facing irreversible climate impacts.
6. Focus on Nature-Based Solutions: Prioritizing ecosystem-based adaptation strategies, such as mangrove restoration and reforestation, can deliver multiple benefits, including climate resilience, biodiversity conservation, and sustainable livelihoods.

case Study: Bangladesh – A Leader in Adaptation

Bangladesh is frequently cited as a leader in climate adaptation, despite being highly vulnerable to climate change impacts. The country has implemented a range of prosperous adaptation measures,including:

* Cyclone Preparedness Programme: A comprehensive early warning system and evacuation plan that has significantly reduced cyclone-related fatalities.

* Climate-Resilient Agriculture: Promoting drought-resistant crop varieties and water management techniques to enhance food security.

* Coastal Afforestation: Planting mangrove forests to protect coastlines from erosion and storm surges.

However, even Bangladesh requires significantly more international climate finance to scale up its adaptation efforts and address the growing challenges posed by climate change.

Benefits of Investing in Climate Adaptation

Investing in climate adaptation isn’t just about mitigating risks; it’s about unlocking significant economic and social benefits:

* Reduced Disaster Losses: Proactive adaptation measures can significantly reduce the economic and human costs of climate-related disasters.

* Enhanced Food Security: Climate-resilient agriculture can ensure stable food supplies and protect livelihoods.

* Improved Public Health: Adaptation measures can reduce the spread of climate-sensitive diseases and protect vulnerable populations.

* Sustainable Economic growth:
