Notre Affaire à Tous filed a legal action with the Conseil d’État against the French government, arguing France has not met its equitable share in global climate mitigation given its historical responsibility and financial capacity.

This marks the fourth climate-related lawsuit against France, continuing a campaign that includes a 2021 ruling for insufficient emissions reductions and a recent Conseil d’État decision demanding further measures to reach 2030 targets.

The case seeks a ruling that France shows a persistent delay in reducing greenhouse gas emissions and fails to meet its fair contribution to climate action.

The group expects a court decision in 2026, with a late-2026 ruling anticipated as stated by Jérémie Suissa, the general delegate of Notre Affaire à Tous.

The report notes ongoing subscriber-only content and references related Le Monde sections on Environment and Climate Change.

The first decision is anticipated in 2026 and is part of a process to push for a more equitable distribution of climate efforts nationally and internationally.

The coalition cites recent filings by NGOs in June 2025 before the Conseil d’État aimed at strengthening adaptation to climate change, described as unprecedented in Europe.

In 2024, France’s greenhouse gas emissions fell by 1.8%, well below the roughly 5% annual reduction target, raising concerns about the political and budgetary outlooks for climate action.

Assessment from Citepa shows a slow pace of emission reductions, with an expected 0.8% decrease projected for 2025.

The objective of the legal action is to compel the state to acknowledge its fair share in the global climate effort and to recognize a persistent delay in reducing emissions.

The advocacy follows earlier constitutional rulings, including the 2021 high-profile verdict against the state in the so-called ‘Affaire du siècle’ over climate inaction.

Notre Affaire à Tous filed a new appeal on January 11, 2025 with the Conseil d’État, named the 'Procès pour la part juste'.
