Adaptation needs in emerging markets and developing economies (EMDEs) are rising rapidly, yet current financing assessments systematically underestimate the scale of the challenge. This paper calls for a shift from headline finance targets towards strategies that fully integrate cost of capital considerations, combining concessional finance, revenue mobilisation, and structural reforms to unlock durable and scalable investment in climate adaptation in EMDEs.

This report, originally published in French in September 2025, is a contribution to the public debate on adaptation in France. The methodologies applied, the data collection process, as well as the analytical framework proposed, may inform broader discussions in Europe, as the preparations for an EU integrated framework for European climate resilience and risk management are well underway. 

Les choix d’investissements des secteurs agricoles et alimentaires des années à venir sont déterminants. Pour pérenniser leurs productions et faire face aux crises, les secteurs agricoles et alimentaires français doivent évoluer vers des systèmes plus résilients et durables. L’enjeu est d’autant plus crucial que différentes vagues d’investissements sont en cours ou à venir dans ces secteurs. Dans cette étude, I4CE a estimé qu’environ 100 milliards d’euros d’outils de production agricoles et alimentaires sont affectés par la transition. Une coordination et une planification des investissements semblent incontournables, notamment pour en limiter les coûts.

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.

National Public Banks (NPBs) and Subnational Public Financial Institutions (SPFIs), including development banks and agencies as well as climate and green funds at the subnational level, play an increasingly vital role in financing climate action and the just transition. While national governments provide frameworks aligned with nationally determined contributions (NDCs), actual implementation occurs largely at the subnational level, which currently lacks sufficient funding. SPFIs can work as financial intermediaries, as they not only understand local needs and have stronger ties with local governments and businesses, but also access much larger volumes of capital from more diverse sources. 

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.

Europe is levelling up its industrial policy. From the Clean Industrial Deal to proposals for a more flexible EU budget, the Commission signals new ambition to build scale in strategic cleantech sectors and strengthen Europe’s decarbonising industrial base. Yet this firepower risks losing impact if spread too thinly. Limited resources demand sharper focus. As the Draghi Report made clear, Europe must act strategically: understand its industrial strengths and vulnerabilities, prioritise the sectors that matter most, and align funds, regulation, and institutional capacity accordingly. 

Europe is making progress on the clean transition, but the pace is too slow across several parametres. ECNO’s analysis is structured around 13 building blocks of the transition, tracking changes in the six-year trend for nearly 150 indicators and also the expected impact of policies – a new addition to this year’s report. In the 2025 edition, we also analysed the changes through the lens of broader EU objectives, namely competitiveness, resilience, and citizens’ well-being. 

I4CE‘s Landscape of Climate Finance is an overview of climate investments made by households, companies and public authorities. Such investments include retrofitting buildings, purchasing electric vehicles, installing renewable energy, as well as paying for rail, cycling and urban public transport infrastructure.

As climate finance debates evolve from pledges to implementation, this report critically reviews the methodologies and narratives behind existing climate financing needs estimates to examine how they might be used to guide practical efforts in the years to come, and where the most urgent improvements are needed. From headline trillions to actual millions, the challenge ahead is not just about determining how much is missing – the focus should be on closing this gap in practice.

In this year’s edition, we assess these indicators retrospectively—over the past ten years for deep energy retrofits, and over the past five for electric mobility—to identify factors that have improved or worsened economic accessibility to transition solutions in recent years.

Six years after its inception, this study aims to review this mechanism and its projects: what activities are being implemented in the field, what impact are they having on the climate, with what robustness or, on the contrary, what limitations in terms of measurement, environmental integrity, accessibility, etc.? This exercise is also intended to feed into the process of continuous improvement of the scheme and to provide feedback for the current implementation of the European carbon certification framework (Carbon removals and carbon farming: CRCF).

This 2025 edition of the Global Carbon Accounts presents a landscape of carbon pricing instruments through the lens of their current and potential contribution to scale up climate and development finance. Several jurisdictions are already using carbon revenues to support a range of policy objectives, including decarbonization efforts and support for economic actors most affected by the transition. Yet there is still potential for them to further contribute to fill the gap.

With the second edition of our State of Europe’s Climate Investment report, we take stock of the development in investments supporting the climate transition in the EU27. The report assesses the real-economy annual investments needed to meet the 2030 targets set out in the Green Deal and Net Zero Industry Act for the energy, buildings, transport and clean tech manufacturing sectors. We track the actual investments in those sectors in the EU economy, highlight the deficits and analyse challenges to mobilise investments.

This report aims to support better use of financial intermediation by public development banks (PDBs) providing international development finance, helping PDBs work better together as a system, with a common understanding of where they contribute the most to low-emissions and climate-resilient development. It mainly focuses on financial intermediation through on-lending to public (government-owned) financial institutions in developing countries.

With Member States meeting this week to discuss the progress and future of EU R&I funding at the Competitiveness Council a group of civil society, research and cleantech organisations, including I4CE, have today issued an open letter urging EU policymakers to put clean technology research and innovation (R&I) at the centre of the bloc’s long-term […]

Integrating climate indicators into variable remuneration is a burning issue. Although it was removed at the last minute from negotiations on the Corporate Sustainability Due Diligence Directive (CSDDD), the proposal is still very much alive in the policy debate . While the topic is becoming increasingly central to remuneration in large companies, it still appears to be a taboo within the banking sector. This requirement was already included in the European Central Bank's supervisory guidelines as early as 2020, yet it appears to have been largely neglected by banks.

Current food production and consumption trends contribute to a range of public health, social and environmental problems. The need for a transition is no longer in doubt: we must move towards a system that produces healthy food with a low impact on ecosystems, is accessible to all, and ensures fair remuneration for producers. There’s no denying that the questions we raise here are politically and socially sensitive, as food is deeply connected to cultural, economic, environmental and health issues. Nevertheless, it is essential to develop ways to foster open discussion. IDDRI and I4CE have therefore joined forces with several other actors to provide insights for the debate.

Published a year, this exploratory report aims to lay the groundwork for a dialogue on the potential role of commercial banks, property insurance companies and asset management firms in supporting investments for real estate adaptation and providing appropriate financial services. It draws on initial testimonies from financial institutions and real estate professionals in France.

The 3rd French national climate change adaptation plan (PNACC3) seeks to generalize an "adaptation reflex" in all public investments and all public support for investment. Operationalizing this ambition is essential for Stop investing in infrastructure, buildings and equipment that will not be ready to cope with the consequences of climate change; Seize the best opportunities available by taking advantage of investments already planned to strengthen the level of adaptation of the French economy at lower cost.
