The recurring disagreement over climate finance has once again emerged as a major challenge at the United Nations Climate Summit, COP31, in Antalya, Türkiye. As representatives from developed and developing countries negotiate climate commitments, the central question remains unresolved: how much financial support is actually reaching vulnerable nations, and whether it is being delivered in a form they can afford and access.
For developing economies such as India, climate finance is not simply a question of international accounting. It is closely linked to the ability to protect communities from extreme weather, strengthen infrastructure, secure water and food supplies, and expand access to cleaner energy without placing excessive pressure on public finances.
The Gap Between Climate Finance Commitments and Actual Payments
Developed countries often highlight the growing amounts of climate finance they report mobilising for developing economies. However, developing nations argue that headline figures do not necessarily represent money received and available for climate-related projects.
The distinction between financial commitments, approved funding and actual disbursements is central to the disagreement. A project may be announced or approved, but the funds may take considerable time to reach the country or community that needs them.
A November 2026 analysis by ONE Data illustrates this concern. It estimated that developed countries provided $60.4 billion in public climate finance payments to developing countries in 2024, compared with the OECD's reported figure of $101.6 billion for the same year. The analysis used a different methodology focused on tracing actual payments rather than relying primarily on reported commitments.
These figures reflect different accounting approaches and should not be treated as directly interchangeable. Nevertheless, the difference highlights why developing countries are demanding greater transparency over how climate finance is measured and reported.

Why Developing Countries Need More Predictable Funding
Climate finance is essential for countries facing increasing exposure to climate-related risks. Developing economies need investment to strengthen flood protection, improve water management, develop climate-resilient agriculture and prepare cities for extreme heat.
They also require substantial resources to expand renewable energy, modernise electricity networks and support industries as they transition towards lower-emission technologies.
However, developing countries argue that the terms of funding matter as much as the total amount. Heavy reliance on loans can increase debt burdens, particularly for countries already facing fiscal constraints.
For this reason, many governments in the Global South are seeking predictable public funding, concessional finance and grant-based support rather than depending primarily on private investment or loans.
The debate is therefore about both the quantity and the quality of climate finance.
Paris Agreement Obligations Remain at the Centre of the Debate
A key part of the disagreement concerns Article 9.1 of the Paris Agreement, which establishes that developed countries shall provide financial resources to assist developing countries with climate mitigation and adaptation.
Developing countries argue that this obligation must remain central to international climate negotiations. They maintain that voluntary financial announcements and broader investment targets cannot replace the responsibilities already established under the agreement.
The debate has gained renewed importance following the adoption of a new collective climate finance goal at COP29 in Baku in 2024. The agreement calls on developed countries to take the lead in mobilising at least $300 billion annually for developing countries by 2035, while also calling for the scaling up of climate finance from public and private sources to at least $1.3 trillion annually by that year.
COP31 Brings the Disagreement Back to the Negotiating Table
The climate finance dispute has become a prominent issue at COP31, which began in Antalya on November 9, 2026.
Negotiations over the summit's agenda exposed differences between developed and developing countries. A standalone Climate Finance Work Programme was included in the adopted agenda following discussions, although proposals for separate agenda items on tripling adaptation finance and climate-related trade measures were not accepted.
The work programme is expected to provide a platform for examining existing climate finance commitments, including their delivery, accessibility and predictability.
India has also reiterated its position that developed countries must fulfil their climate finance obligations under Article 9.1. In its opening statement at COP31, India highlighted equity, adaptation and a just transition as essential elements of a fair international climate response.

Adaptation Finance: A Particularly Urgent Challenge
One of the most pressing concerns is the shortage of funding for climate adaptation. While reducing emissions is essential to limiting future warming, countries must also invest in measures to cope with climate impacts that are already occurring.
The scale of the funding gap is significant. According to the United Nations Environment Programme's 2026 Adaptation Gap Report, developing countries could require approximately $305 billion annually by 2035 to meet their adaptation needs. International public adaptation finance from developed countries stood at an estimated $28.2 billion to $31.7 billion in 2024.
This gap highlights the difficulty of protecting vulnerable populations when available international support remains considerably below estimated requirements.
For countries with limited fiscal resources, insufficient adaptation funding can make it harder to strengthen agricultural systems, improve disaster preparedness and protect essential infrastructure.
Historical Responsibility and Climate Equity
Another dimension of the dispute is the principle of climate equity. Developing countries argue that wealthy nations accumulated much of their economic prosperity during periods of extensive fossil-fuel consumption and therefore have a greater responsibility to support countries facing climate impacts.
They also point out that developing economies must continue creating jobs, expanding electricity access and improving living standards. A transition towards cleaner energy should not prevent them from pursuing legitimate development priorities.
India has consistently supported the principle of Common But Differentiated Responsibilities and Respective Capabilities, which recognises that countries have different historical contributions to climate change and different capacities to respond.
At COP31, India reiterated that public finance from developed countries remains important for enabling climate action and meeting adaptation requirements across the Global South.

Why Climate Finance Will Continue to Shape Future Climate Agreements
The recurring disagreement reflects a broader challenge in international climate cooperation: countries may agree on the urgency of climate action but differ significantly over who should finance it, how funding should be distributed and what obligations governments must fulfil.
For developing nations, credible financial support is essential to turn climate commitments into practical projects. For developed countries, discussions increasingly involve the scale of public contributions, the role of private investment and the measurement of funds mobilised.
The success of COP31 will therefore depend not only on the announcements made during negotiations but also on whether countries can establish a more transparent and dependable system for delivering financial assistance.
Ultimately, climate finance is not simply about setting ambitious targets. It is about ensuring that the resources promised translate into accessible funding, stronger infrastructure and meaningful protection for communities facing climate risks.
