COP30 Maps $1.3 Trillion Climate Finance for Developing Countries

The COP30 Presidency has released a new report outlining how international climate finance for developing countries could reach between US$1.27 trillion and US$1.41 trillion annually by 2035 through coordinated financial reforms and investment measures. Presented on 8 November 2026 ahead of COP31 in Antalya, Türkiye, Implementing the Baku to Belém Roadmap to 1.3T identifies six financing sources and introduces frameworks to accelerate investment and monitor progress. Without additional interventions, the report estimates that annual international climate finance would reach only US$458 billion to US$461 billion by 2035, substantially below the global US$1.3 trillion objective.

The assessment builds on the Baku to Belém Roadmap presented jointly by the COP29 and COP30 Presidencies in November 2025. Under the COP30 Global Mutirão Decision, countries agreed to urgently advance measures to scale climate finance for developing nations to at least US$1.3 trillion annually by 2035, drawing on public and private sources. The new report examines how that objective could be achieved through changes in financing mechanisms, investment policies and international financial cooperation.

 

Six Financing Sources Could Deliver US$1.41 Trillion Annually

 

The report identifies six sources of climate finance that could help achieve the 2035 target: concessional finance, private investment, South-South cooperation, the channeling of Special Drawing Rights (SDRs), innovative financing mechanisms, and carbon markets. These channels are intended to expand available funding while improving access to capital for developing economies. The projected range of US$1.27 trillion to US$1.41 trillion depends on governments, development banks and private investors implementing the necessary financial and policy measures.

The substantial difference between the report's enhanced financing scenarios and its business-as-usual estimates illustrates the scale of intervention required. Under existing trajectories, projected annual finance of approximately US$460 billion would cover only around one-third of the US$1.3 trillion objective. Increasing concessional resources, mobilizing private investment and strengthening financial institutions are therefore central to the proposed implementation strategy.

Five Financial Reform Priorities Guide Implementation

 

The new assessment expands on five interconnected reform priorities established in the 2025 Baku to Belém Roadmap: Replenishing, Rebalancing, Rechanneling, Revamping and Reshaping. These priorities focus on increasing grants and concessional resources, improving fiscal space and debt sustainability, directing more private capital toward climate investment, strengthening institutional capacity, and reforming financial systems to support more equitable capital flows.

The original roadmap identified more than 75 potential measures across these priorities. The 2026 report moves towards evaluating how different financing sources could contribute to the overall target, linking financial reforms with investment opportunities. This approach recognizes that expanding the total volume of finance alone will not resolve barriers associated with debt burdens, capital costs and limited institutional capacity in developing countries.

 

New Framework Tracks Climate Finance Delivery and Impact

 

To support implementation, the COP30 Presidency has introduced a 5x5 Implementation Framework developed alongside the Independent High-Level Expert Group on Climate Finance. The framework connects the five reform priorities with major climate investment needs and operates through three pillars: country-led investment, coalitions supporting key transitions, and mobilization of the US$1.3 trillion capital stack. It is designed to improve coordination between national investment priorities and the institutions that can finance them.

The report also introduces the Climate Finance Action Compass, developed using tools from the Climate Policy Initiative. It assesses progress across four dimensions: Scale, Speed, Reach and Impact. The framework examines whether financing is increasing sufficiently, being deployed quickly, reaching the countries and sectors most in need, and delivering measurable climate and development outcomes. This creates a basis for evaluating financing performance beyond aggregate commitments.

COP31 Brings Financing and Climate Implementation Together

 

The report arrives alongside two COP30 Presidency roadmaps addressing the transition away from fossil fuels and the commitment to halt and reverse deforestation and forest degradation by 2030. Together, the three documents connect financing requirements with major areas of climate implementation, including energy transformation and forest conservation. Their publication also provides a reference for discussions as COP31 begins in Antalya and countries prepare for the second Global Stocktake of the Paris Agreement.

COP30 President André Corrêa do Lago wrote in the report's foreword that “the evidence exists, the instruments are known”, highlighting the availability of financing mechanisms that governments and financial institutions could use to accelerate implementation.

The report remains a voluntary, non-prescriptive contribution from the COP30 Presidency, not a binding financial agreement. Achieving the projected financing levels will depend on governments, development banks, central banks, and private investors translating the proposed measures into funding commitments and actual investment flows. The central challenge for COP31 and subsequent negotiations will be moving from identified financing pathways to measurable increases in capital reaching developing economies.
