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.

In a challenging geo-political context, Europe has a window of opportunity to lead on both climate action and industrial competitiveness. As Mario Draghi highlighted in his report last year, this can only happen if decarbonisation ambitions are backed by real investment - and there is an urgent need to boost those investment. The European Commission followed suit and pledged to be an “Investment Commission,” while reaffirming its commitment to implement the 2030 emission reduction targets and to stay to course on the longer-term targets.

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.

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. 

As Donald Trump kicks off another presidential mandate in the US, there is no turning away from the EU’s major challenges of competitiveness, energy security and decarbonising the economy. With a new European Commission in place since December 2024, the roll out of initiatives addressing those challenges can begin. Whilst a lot of focus goes […]

2025 begins with a new French government and a new budget debate, but with the same challenge as last year: how to reduce the deficit without putting the brakes on investment in the climate transition? Climate investments are the best investments we can make, according to the new Minister of Economy Éric Lombard. He's right: any delay weakens our energy security and our position in the international race for cleantech, not to mention the pace of decarbonisation of our economy.

To tackle the challenges of competitiveness and well-being of future generations, Europe needs to accelerate the climate transition. This will require sizable investment, both public and private. National governments must thus embrace and the EU must facilitate investments in climate transition. As the next European Commission prepares to take office, the challenges facing the College are stark. The recent report by Mario Draghi makes clear that there is an urgent need to invest in European competitiveness and innovation, while accelerating the decarbonization of the continent's economy, to avoid a “slow agony of decline” for the block.

The ecological transition can only happen if all households have access to solutions – public transport, electric vehicles, home insulation, heating upgrades, etc. The issue of the access to transition solutions is therefore crucial for climate policies. Special attention should be paid to low- and middle-income households, as the necessary investments may not be sustainable for them. 

The Members of the European Parliament (MEPs) will audition the European Commissioner-designates in early November. The hearings are a crucial moment to seek commitment from the EU’s next executive team on the priorities for the coming five years and how they will delivered – including on the urgent issue of investment in the climate transition.

Every year, the start of the budget debate in France is an opportunity to ask a number of questions: How much is public spending on climate? What is this money spent on? Which actors, both public and private, are on the receiving end? And above all: how should this spending develop in the future? Many numbers have been produced in France over the last few years and it is easy to get lost in the shuffle. This is why we wrote this handbook. We have gathered the information that we consider most important and tried to highlight what we know, what we do not yet know, and the key debates in France that politicians will have to hold and where they will have to quickly find compromises.  

A comprehensive and up-to-date overview of the challenge of financing the low-carbon transition at the local level in France. Local authorities have a major role to play in achieving France's 2050 carbon neutrality goals, as set out in the Stratégie nationale bas-carbone (SNBC). Due to their property and responsibilities, they must make numerous climate investments, implement strategies and action plans, and deploy initiatives to mobilise local actors.  

Climate adaptation, preparedness and solidarity features prominently in the Political Guidelines for the new EU mandate, unveiled by Commission President Ursula von der Leyen in July. And with good reason: infrastructures, access to water, food production, life in European cities - to name but a few - are increasingly impacted by the effects of climate change. Europe urgently needs to prepare better for the impact of climate change, was the message in the European Climate Risk Assessment published by the European Environment Agency earlier this year.

To address the growing impacts of heatwaves on economic activities and populations, the adaptation of the building sector is becoming a new imperative. While the question of “how” to adapt has been the subject of numerous studies, the question of “how much” has so far received little attention. To move forward on this issue, we present in this report: an overview of current knowledge regarding the costs of adapting the building sector to heatwaves and the methodology we used to estimate the additional costs of adapting to heatwaves, based on available information and discussions with experts.

Assessing the economic implications of climate policies is essential for steering public action. Sig­nificant progress has been achieved in assessing the costs of mitigation, particularly with the publication in 2023 of the report on the economic implications of climate action. However, as the Cour des Comptes noted in its 2024 annual public report, numerous issues surrounding adaptation continue to emerge. Our recent work has nev­ertheless enabled us to draw five initial conclusions on the subject.

France is facing a climate investment deficit relative to its climate objectives. Today, these investment are already putting a strain on public finances, whether in terms of investing in public facilities or co-financing projects by households and business. Increasing climate investments is therefore a challenge for public finances. But the scale of the challenge varies, depending on future policies. So what room for manoeuvre is there in terms of climate-related public spending needs?

Assessing the state of progress to inform next steps in policy-making. The European Union (EU) is on its journey to become climate neutral by 2050. This multigenerational project holds many societal, economic, and environmental opportunities. At the same time, it is of unprecedented scale and implies considerable changes to the current systems, which need to be anticipated and addressed for the transition to be fair and acceptable to all. Regular progress checking is the key to understanding where the EU stands on the journey. It allows to identify challenges and opportunities and take targeted policy action guiding investment, supply, consumption, and societal development. There is still no official, comprehensive, and regular EU-wide progress monitoring to achieve this. This second ECNO progress check aims to close the current information gap. It provides a comprehensive view on the state of EU progress towards climate neutrality and identifies key areas of action for the next policy cycle.

This week, I4CE launches the first European Climate Investment Deficit report. During a year’s research, we analysed investments in 22 sectors of the EU27 economy that are critical for the EU to deliver its 2030 climate and energy security objectives. The European Green Deal is gaining economic momentum, as climate investments in the EU grew 9% in 2022, reaching […]

Climate investments in the EU economy grew by 9% in 2022. This report finds that the European Green Deal is gaining economic momentum but investments in modernising energy, transport, and buildings must still double for the EU to hit 2030 climate targets.

There is a broad consensus that private finance has an important role to play in financing the climate transition, given the scale of needs and the constraints on public finances. Beyond investments in climate alone, all financial activities must be reoriented to be compatible with the transition. This shift cannot take place on a voluntary basis at the scale and speed required. The inactivity of financial players, the weight of past financing, and the demands of shareholder profitability limit the effectiveness of voluntary international initiatives to which private financial players commit themselves.

The issue of access to the transition for all households, in particular, for low- and middle-income households, has become central to the French public debate, as recently shown by the French President’s speech on ecological planning, when he referred to “an ecology that is accessible and fair, that leaves no one without a solution”. This growing awareness is particularly in response to the yellow vests protests: expecting households to take steps towards the transition if they have no access to solutions (electric cars, public transport, home insulation, heating upgrades) results in a rejection of transition policies and leads us collectively to a dead end
