Model UN Background Guide

Committee: Economic and Financial Committee (ECOFIN, GA2)
Topic: Climate Finance for Developing Economies
Conference Year: 2026

Topic Background

Climate finance refers to the local, national, or transnational financing—drawn from public, private, and alternative sources—that seeks to support mitigation and adaptation actions addressing climate change. For developing economies, climate finance is critical to managing the dual challenge of sustainable development and climate resilience. These countries are often the most vulnerable to climate impacts such as extreme weather events, sea level rise, and agricultural disruption, yet they typically have the least financial resources to respond.

Historically, climate finance gained prominence following the 1992 United Nations Framework Convention on Climate Change (UNFCCC), which recognized the need for financial flows from developed to developing countries. The Kyoto Protocol and later the Paris Agreement (2015) further codified commitments to mobilize climate finance, notably the goal of mobilizing $100 billion annually by 2020 from developed countries to support developing nations’ climate action. However, this target has been contentious, with debates over definitions, sources, and adequacy of funding.

In recent years, the urgency of climate finance has intensified due to worsening climate impacts and the slow pace of global emissions reductions. The COVID-19 pandemic and ensuing economic disruptions further complicated financial flows. Additionally, developing countries face challenges accessing funds due to complex application processes and the predominance of loans over grants, which can exacerbate debt burdens. The COP26 and COP27 conferences highlighted the need to scale up climate finance, improve transparency, and address loss and damage financing.

ECOFIN’s 2026 agenda includes climate finance for developing economies because of the critical intersection between economic development, environmental sustainability, and international financial cooperation. As countries negotiate post-2025 financial frameworks and mechanisms, ECOFIN must consider innovative funding sources, equitable burden-sharing, and mechanisms that support both mitigation and adaptation.

Key Actors

• Developed Countries (Annex I Parties under UNFCCC): Countries like the United States, European Union members, Japan, Canada, and Australia are the primary providers of climate finance. They face pressure to meet or exceed previous pledges and to increase transparency regarding the sources and types of funds (grants vs. loans).

• Developing Countries (Non-Annex I Parties): Large emitters such as China, India, Brazil, and South Africa balance development priorities with climate goals. Least Developed Countries (LDCs) and Small Island Developing States (SIDS) are especially vocal about the need for adaptation finance, loss and damage compensation, and grant-based funding.

• Multilateral Development Banks (MDBs): Institutions like the World Bank, Asian Development Bank, African Development Bank, and the Green Climate Fund (GCF) serve as intermediaries and financiers of climate projects. Their policies and funding priorities significantly shape climate finance flows.

• United Nations Entities: The UNFCCC Secretariat, United Nations Development Programme (UNDP), and UNEP play advisory and coordination roles, providing technical assistance and monitoring finance mobilization.

• Private Sector and Philanthropic Organizations: Increasingly important in mobilizing capital through green bonds, climate funds, and blended finance mechanisms, though their engagement varies widely by region and sector.

Bloc Positions

• Developed Countries Bloc: Generally emphasize transparency, accountability, and leveraging private finance alongside public funds. They advocate for measurable, verifiable results and often promote market-based mechanisms such as carbon trading. While committed to financing, some resist legally binding financial obligations or increasing grant-based funding.

• Emerging Economies Bloc: Countries like China, India, Brazil, and South Africa seek greater recognition of their development needs and emission reduction efforts. They call for increased financial support, technology transfer, and capacity building, often emphasizing the principle of “common but differentiated responsibilities.” They may advocate for more flexible funding mechanisms that support both mitigation and adaptation.

• Least Developed Countries and Small Island Developing States Bloc: These countries prioritize adaptation finance, loss and damage compensation, and grant-based funding to avoid increasing debt burdens. They often call for a dedicated financing facility for loss and damage and stress the urgency of scaling up funds to meet immediate climate vulnerabilities.

• Oil and Gas Exporters Bloc: Some oil-producing developing countries may express concerns about the economic impacts of climate finance conditionalities on fossil fuel industries and advocate for just transition frameworks that include financial support for economic diversification.

Past UN Action

• UNFCCC COP Decisions: Various COP decisions have addressed climate finance, including the establishment of the Green Climate Fund (GCF) and the Standing Committee on Finance. The Paris Agreement (2015) reaffirmed the $100 billion annual mobilization goal and enhanced transparency frameworks.

• General Assembly Resolutions: GA resolutions have supported climate finance mobilization and called for enhanced cooperation between developed and developing states, though these have largely been non-binding.

• ECOFIN and GA2 Reports: Previous ECOFIN sessions have discussed sustainable development financing and climate-related economic policies, but climate finance specific resolutions remain limited within GA2’s mandate, underscoring the need for more concrete action in 2026.

Questions a Resolution Should Answer

1. How can the international community enhance the mobilization of climate finance to meet and exceed the $100 billion annual target post-2025?
2. What balance should be struck between grants, concessional loans, and private finance to ensure equitable and sustainable funding for developing economies?
3. How can access to climate finance be simplified for developing countries, especially LDCs and SIDS, to overcome bureaucratic and technical barriers?
4. What mechanisms can be established or improved to finance loss and damage associated with climate change impacts in vulnerable developing countries?
5. How can transparency and accountability in climate finance reporting be improved to build trust between providers and recipients?
6. What role should multilateral development banks and private sector actors play in scaling up climate finance for mitigation and adaptation projects?
7. How can climate finance support just transition strategies in developing economies reliant on fossil fuel industries?

Further Reading

• UN Documents: Official reports and decisions from the UNFCCC COP sessions, Green Climate Fund annual reports, and General Assembly resolutions provide authoritative insights into negotiated commitments and institutional frameworks.

• Think-Tank Reports: Research and policy analyses from organizations such as the Overseas Development Institute (ODI), Climate Policy Initiative (CPI), and World Resources Institute (WRI) offer detailed assessments of climate finance flows, gaps, and innovative financing mechanisms.

• News Outlets: Reputable international news sources like Reuters, Al Jazeera, and the Financial Times track real-time developments in climate negotiations, funding pledges, and geopolitical dynamics influencing climate finance.
