Departmental strategy for adapting to climate change
The Department of Loire-Atlantique is a French local authority with a population of 1,445,171 living in an area of 6,874 km².

Overview of the project
The Loire-Atlantique department’s climate strategy is based on three pillars: supporting local areas in adapting to climate change, integrating these issues into internal policies, and raising awareness among the general public. Following an analysis of climate impacts, committees of experts, technicians and elected representatives identified vulnerabilities and defined joint projects with the EPCIs for 2025.
The aim of the departmental strategy for adapting to climate change is to launch a multi-actor∙ices dynamic, paying particular attention to the specific features of the area and the vulnerabilities of the most vulnerable sections of the public.
Ongoing research
Projet toujours en cours
Since 2023, the Department has mobilised a large number of people: two steering committees, three expert committees, three technical committees, 23 interviews with departments and three newsletters. In December 2024, the diagnosis of vulnerabilities was shared with more than 300 elected representatives and partners.
The Department has raised awareness of the issue among stakeholders via diagnoses, letters and meetings, and has worked with EPCIs and partners to contribute to the PNACC3. In 2025, several priority projects will be launched on water, food and natural environments. Internal mobilisation is being stepped up with a technical committee and a communication plan.
The project is financed by the French government as part of the Green Fund and by the French Environment and Energy Management Agency (ADEME). The Department will provide a proportion of its own funding.
organisation
With over 1.4 million inhabitants, Loire-Atlantique is a department committed to solidarity, education, the environment and social action across an area of almost 7,000 km².
The approach includes a strong link with the territory’s EPCIs, which are mobilised to identify and carry out joint adaptation projects across the territory.
