Environmental taxation is an essential part of the ecological transition. It is a powerful tool for changing the behavior of economic actors, and also a new source of revenue for the State.


Environmental taxation in France is increasing: the 2018 Budget law increases the price trajectory of the “climate and energy contribution” to reach € 86.2 / ton CO2 by 2022.


However, it raises legitimate concerns that regularly drive debates in the National Assembly: on the one hand, low-income households, or citizens living in rural and peri-urban areas may be severely impacted by this increase in their energy and transportation expenses ; on the other hand, the debate on the competitiveness of our economy is entirely legitimate, and should not be avoided. The collection of these taxes and the redistribution of associated revenues must address these concerns if we want to increase our ambition in terms of environmental taxation.


Supported by the former president of the National Assembly and now Minister of Ecological and Solidarity Transition, François de Rugy, this conference initiated by 14 members of parliament and the think-tank Institute for Climate Change Economics (I4CE) was an opportunity to exchange, between parliamentarians and stakeholders, on this complex and often conflicting subject.


The conference took the form of three discussions involving experts such as Lord Nicholas Stern, Professor at the London School of Economics and chair of the Grantham Research Institute on Climate Change and the Environment, and Alain Quinet, Chairman of the Commission on Social Value of Carbon in France. A tax expert from the OECD, representatives of foreign states as well as the Abbé Pierre Foundation completed this panel to give it the social and international dimension that the subject calls for.


All the debates was moderated by Benoit Leguet, Director General of I4CE.

    Maximising benefits of carbon pricing through carbon revenue use: A review of international experiences

    Carbon pricing policies and their revenues are part of the tools available that can help fill the climate finance gap. With raising revenues from carbon taxes and emission trading systems (ETSs) that have tripled since the Paris Agreement, and an upward trend that could continue in the medium-term, ‘how to use carbon revenues’ has become a crucial question. This report, prepared as an activity of the EU-funded European Union Climate Dialogues (EUCDs) project, aims to inform policymakers and practitioners on lessons learned and ways forward on the use of carbon revenues, with a comprehensive approach based on a review of international experiences.

    I4CE’s recommendations to the European Banking Authority on prudential transition plans

    The European Banking Authority (EBA) is clarifying how the banks should frame their “transition plan” as required by the EU prudential regulation. The transition plan is the bank’s strategic roadmap to prepare for the transition to a sustainable economy as framed by the jurisdictions they operate in, including an EU climate-neutral economy. It has been introduced in several EU regulatory frameworks, including as a disclosure requirement arising from the CSRD. The prudential framework and the EBA are focusing on a specific angle: how the banks plan to manage their financial risks related to the transition. EBA’s framing of these plans will be key to determine whether the banks will manage their financial risks consistently with the broader need of financing the transition to a low-carbon economy.
