The unlocked potential of carbon revenues to help fill the climate finance gap

Climate negotiations are taking place next week in Bonn, with finance once again high on the agenda.

 

COP 29 ended last year with a New Collective Quantified Goal (NCQG) –revised climate finance target to replace the USD 100 billion goal. The NCQG decision put forward a commitment by developed countries to lead in providing USD 300 billion per year by 2035 for developing countries, as well as a proposal to work on a roadmap to scale up climate finance for developing countries to reach a level closer to the estimated needs –the ‘Baku to Belem Roadmap to 1.3T’ (USD 1.3 trillion). The latter must be delivered at the end of the year at COP 30, and strong efforts are being put in the task by the Brazilian Presidency.

 

Yet the current global economic and geopolitical context has led to an increasingly complex landscape for international climate and development finance. Cuts in Official Development Aid (ODA) and climate finance have spread since the new Trump administration took office in the United States, as part of a part of a broader rollback of climate and development aid policies. In Europe, a growing focus on competitiveness and security, combined with fiscal constraints in several countries, is already having an impact on EU climate investments. While emerging and developing countries are confronted with increasingly limited fiscal space and debt burden that hinder their ability to invest on climate and development goals.

 

In this challenging landscape, exploring diverse policy tools to mobilize and align financial flows is more crucial than ever. Carbon pricing instruments and their revenues are part of the tools available that can help with this task. The 2025 edition of the Global Carbon Accounts, launched this week in the context of the Innovate4Climate 2025 in Sevilla, provides insights into both current and untapped potential for carbon pricing revenues to support a range of policy goals. USD 103 billion in revenues collected in 2024, 56% of revenues used for environment and development objectives, and at least USD 75 billion in revenue forgone… These are some of the key figures you will discover when reading the new edition of I4CE‘s Global Carbon Accounts.

    COP30: On Financing, the Time for Negotiation Is Over

    “What agreement will the negotiators reach?” is the question that is usually on climate practitioners’ minds at this time of the year. However, this time, it is a new impetus that is needed, not another agreement. 10 years after the Paris Agreement, the Brazilian COP30 presidency has rightly shifted the focus to execution, making this edition “the implementation COP.” On financing, the objectives set at COP29 are clear: developing countries should receive $300 billion per year by 2035 from developed countries (NCQG), and mobilise $1.3 trillion per year from all actors. The newly published “Baku to Belém” roadmap proposes solutions to meet the targets. We now have objectives and a list of (theoretical) means to achieve them. How do we move to implementation?

    From Pledges to Progress: Climate Finance a Decade After Paris

    Nearly a decade has passed since the Paris Agreement elevated finance to the heart of the climate agenda, embedding in Article 2.1(c) the ambitious goal of aligning global financial flows with low-emission, climate-resilient development. But for all the talk of “shifting the trillions,” we remain far from course.

    From targets to action: the climate finance agenda needs a new impetus in Belèm

    Ten years after the adoption of the Paris Agreement, what progress has been made to make financial flows consistent with a pathway towards low greenhouse gas emissions and climate-resilient development (the ambition set out in Article 2.1(c) of the Agreement)? And what is needed going forward? Although we still lack a comprehensive assessment of progress, this article draws on existing analysis of what can help align financial flows and examines the efforts made by governments and the financial sector to this end. It highlights a development in the debate towards a country-driven approach and a focus on real investment needs. It explores ways to overcome existing barriers to action despite a challenging global context. The article advocates that Article 2.1(c) should be viewed not as a stand-alone provision, but as something that requires full implementation of all the provisions of the Paris Agreement. It also calls for a shift from a target-focused to an action-focused finance agenda and discusses how the COP30 in Belém can contribute to this.
