Summary:
On 7 April 2025, a group of five individuals litigants and nine civil society organisations presented a request for adaptation measures to the French authorities. Building on GHG emissions reductions litigation, including the ECtHR’s 2024 KlimaSeniorinnen case, this legal action seeks adaptation measures by the French government. The litigants, who are supported by Oxfam France, Notre Affaire à Tous, and Greenpeace France, seek a revision of the third National Plan for Adaptation to Climate Change (PNACC 3) and, more broadly, the adoption of any useful measures to ensure or reinforce France’s adaptation to the effects of climate change. The action argues that the State has a general obligation to take adaptation measures, which must be aimed in particular at strengthening adaptive capacities, increasing resilience to climate change and reducing vulnerability to such change (I.A), and by sectoral and cross-cutting obligations (I.B).
This obligation, they argue, flows not only from domestic constitutional law, but is also clarified and reinforced by international and EU law (including the UNFCCC and the Paris Agreement) and by the law of the Council of Europe, specifically the European Convention on Human Rights. This instrument, they argue, drawing on the ECtHR’s recently climate case-law and its broader environmental jurisprudence and focusing particularly on the right to respect for private and family life (Art. 8 ECHR) and the right to life (Art. 2 ECHR), obliges the State to put in place an appropriate legislative and regulatory framework to effectively protect human life and health against the risks and consequences of climate change. It also requires the State to take preventive measures of a practical nature, in order to protect citizens whose lives may be at risk, and to mitigate the most serious consequences of climate change. And, finally, it requires the State to ensure the effective application of the framework and of the adaptation measures thus put in place, on the basis of the best available science. Reiterating long-standing case-law of the ECtHR, the litigants argue that the French state has an obligation to take all necessary measures to limit exposure to natural risks resulting from climate change, and to ensure that those affected are informed of the existence of such risks.
The action began as a request addressed to the state, which is a procedural requirement under French law before bringing a case to the Council of State (Conseil d’État). If the state responds in an unsatisfactory way or not at all, the case can be then be taken to the Council of State.
