COP30: The missed turn to implementation – and the coalitions moving ahead anyway

28 November 2025 - Foreword of the week - By : Guillaume POTTIER

COP30 concluded with an agreement, proving that multilateralism is still alive. However, the results are underwhelming: no push to transition away from fossil fuels, no decision on deforestation, and mixed outcomes on adaptation metrics.  

 

On climate finance, Belém failed to shift from ambition to implementation. Negotiations quickly drifted back to a battle on yet another high-level quantitative target. The decision to triple adaptation funding by 2035 disappointed many, with its distant time horizon, lack of baseline and non-binding wording. COP30 also missed the opportunity to engage with – and build consensus around – concrete measures outlined in the Baku to Belém roadmap to get to $1.3 trillion. Instead, it defaulted to launching new processes – a work programme on climate finance and a ministerial roundtable on the NCQG.  

 

Still, outside negotiation rooms, Belém delivered tangible progress. Public development banks rose to the occasion. For example, multilateral development banks renewed their commitment to climate-smart development. The IDFC – public banks weighing $600 billion annually – confirmed their support to the “transition away from fossil fuels” while negotiators remained divided on the very same item. A large group of public and private financial actors also recognized the importance of  “transformational finance” to unlock systemic climate impacts.

 

Belém showed that coalitions of the willing can drive progress. A good example is the expansion of the Premium Flyers Solidarity Coalition, which now includes 9 countries – Brazil joined as an observer.  

 

I4CE and IDDRI published a report on the use of proceeds from such solidarity levies for development and climate action. Combining analyses of climate finance flows, an assessment of selected countries’ priorities, and a review of existing frameworks for the allocation of debt-free finance, it concludes that there is strong case for investing solidarity levy revenues on adaptation and resilience in Least Developed Countries and Small Island Developing States.

 

Coalitions of the willing are no substitute for multilateral agreements, but they can help unlock them. Ahead of COP31, and with the French presidency of the G7 in sight, I4CE will continue to work with partners to advance an ambitious implementation agenda on climate finance.

    How solidarity levies can help bridge the climate and development finance gap

    The climate and development finance gap is large and widening, as Official Development Assistance (ODA) declines and needs multiply. With shrinking fiscal space in vulnerable countries, solidarity levies are gaining attention as a predictable source of international finance. Launched at COP28 by Barbados, France, and Kenya, the Global Solidarity Levies Task Force (GSLTF) is the main initiative in this space.

    A Paris Climate & Nature Week with a touch of ‘green budget’

    We were proud to contribute to the inaugural Paris Climate & Nature Week hosted by Sciences Po from 27 to 29 October, marking the 10 years of the Paris Agreement. I4CE weighed in on some of our core topics– lessons learnt over the past decade of climate action which can accelerate the  transition; the links between climate and development finance; as well as adaptation and the cost of inaction.

    Bridging the gap: high-level climate & development finance commitments and the reality on the ground

    The 4th International Conference on Financing for Development (FFD4) in Seville represents a milestone for delivering on development (including climate action) goals, a decade after the adoption of the Sustainable Development Goals and the Paris Agreement. The “Seville Commitment” was adopted on June 30th, albeit in the absence of the United States – demonstrating that widespread support remains for a comprehensive package to finance development. However, the outcome also embodies the growing chasm between high-level commitments and the reality of financing for development and climate action on the ground. Recent research by I4CE attempts to bridge this gap on two crucial issues.
