Conferences - By : Sébastien POSTIC, Phd

The French National Assembly and I4CE organized a conference entitled

 

Investigating the Drivers of Approval for Environmental Taxes

 

This conference has been organized by I4CE and fourteen members of the National Assembly, in order to discuss the future of the carbon tax in France.

 

International speakers were invited to bring their insights and share their experience. How to use the revenues of the carbon tax to make it more efficient and acceptable? How to support households and in particular the most vulnerable? Find the interviews and presentations of the speakers, as well as the summary of the discussion.

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.

    Food sovereignty relies on ecological planning

    The upcoming food sovereignty conferences are likely to shape debates on the future of French agriculture in 2026. The main responses provided over the past two years can be summarised as follows: remove production constraints to produce more of everything (both animal and plant products), to recover market shares in France and abroad. Seeking to produce more of everything without considering adaptation or transition is a form of denial, at a time when climate change is hitting farmers hard and regularly, and when our dependence on imported fertilisers and oilseed meals undermines our sovereignty. The conferences must take these considerations into account — otherwise, they will serve only to perpetuate the notion of an illusory sovereignty.

    Which production assets for more resilient and sustainable agricultural and food sectors? Which investment needs? Which stranded assets?

    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.

    Financing carbon farming practices: lessons learnt in France can reinforce the EU level initiatives

    In a challenging economic and political context, especially for the agriculture sector, some incentive schemes can still help bring stakeholders together in climate transition and resilience initiatives. This is the case with carbon certification schemes, which both ensure the credibility of the climate impact of the actions implemented and provide remuneration for farmers and foresters for changes in practices. Some of these measures, such as replacing mineral fertilisers (mostly imported) with organic fertilisers, also help to meet the sector’s needs for resilience and strategic independence, which are crucial in the current context.
