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. 

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.  

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.

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.

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

National budgets, as the main driver of public action, need to be ‘greened’ by governments to achieve the transition to low-carbon, climate-resilient, and sustainable economies. That is, budgeting processes need to ensure sufficient funds are directed towards green activities and are directed away from environmentally harmful ones.

For years, the European Union assumed it would lead the cleantech race because it was the only one running in it. Mistakenly so. With the Inflation Reduction Act, the US quickly catches up. This brief argues that the best EU policy answer to the IRA is an EU long‑term climate investment plan. As the political appetite for such a plan is currently limited, the European Commission should use the political momentum to propose a targeted investment plan that focuses on the development, scale-up, manufacturing and deployment of clean technologies in the EU. It identifies three first bricks that can already be laid out to build this plan.

Long term national climate strategies, such as Long-Term Strategies (LTS) published to the UNFCCC, are key documents developed by governments to envision the transition to a low-carbon and climate resilient economy at the 2050 (or later) time-horizon. As of the beginning of COP 27 in Sharm-el-Sheikh, Egypt, on November 2022, 55 countries had submitted an LTS to the UNFCCC, answering renewed calls for countries to develop such strategies at COP 26. It is expected that additional LTS will be published shortly. 

  Of course, public money will not do everything; but without public money, it seems difficult today to conceive of a transition that is acceptable to all and sufficiently ambitious. With the French presidential campaign about to begin, the budget that the goverment allocates to the transition will certainly be the subject of intense debate. […]

Confronted with a health crisis that has caused a global social and economic shock, the European Union and countries around the world are adopting major economic support programs. Following the initial focus that must be on overcoming the health emergency itself, actions that contribute to climate goals can be an effective part of improving both the economy and the resilience of our society. I4CE’s proposal calls for a public finance package of 7 billion euros per year that is estimated to trigger 19 billion euros of additional public and private investment. Altogether, this package would contribute to the economic recovery post-crisis, while simultaneously reinforcing our society against future shocks without reducing France’s contribution to international climate goals.

The vote on the state budget is a key moment in the fight against climate change. In France,more than 250 budget measures have been identified: expenditures, tax exemptions, taxes, all of which have a significant influence, upward or downward, on national greenhouse gas emissions. 250 reasons to keep a close eye on the state budget. […]

This climate brief highlights that while there is an acceleration of carbon pricing policy implementation, associated revenues are on the rise (USD 32 billion in 2017). This increase raises the issue of the use of revenues. I4CE distinguishes between 4 main uses of carbon revenues: Investment in low-carbon projects; Allocation to the general budget; Reduction […]

The transition to a low-carbon economy implies significant investments in buildings, transport systems, vehicles, power plants, industry, agriculture. However scaling-up those investments to meet climate and energy objectives requires an improved knowledge base in investments and financial flows in those sectors, as well as policy assessment tools.   This is why I4CE has developed since 2013 a “Landscape of domestic climate […]

The Landscape of climate finance is a comprehensive study of domestic financial flows in favor of climate and the broader energy transition in France. The study maps the flows supporting investments leading to greenhouse gas mitigation across the French economy. The principal objective of the study is to support public debate on the role and relevancy of […]

In September 2016, I4CE updated its database on carbon pricing policies and published a panorama of explicit carbon pricing policies. This panorama presents an implementation timeline, a world map and a table that together, provide information on: the jurisdictions that have implemented or plan to implement explicit carbon pricing policies, the type of instrument chosen, […]

This Brief has been prepared for the High Level Dialogue on Carbon Pricing taking place at the global Climate Chance Summit for Non-state actors organised in Nantes, France from the 26th – 28th September 2016. Carbon pricing is a valuable economic tool which can help towards achieving the necessary emissions reductions to mitigate climate change. […]
