Comment les Français perçoivent les enjeux environnementaux ?

Commissariat général au développement durableSep 7, 2026

Chaque année, le service statistique du Commissariat général au développement durable publie des études pour mieux comprendre le lien que les Français entretiennent avec l’environnement. Deux baromètres complémentaires permettent d’observer les tendances de fond comme les évolutions récentes : l’un s’intéresse aux pratiques concrètes (gestes du quotidien, équipements, consommation), l’autre aux opinions (perceptions du changement climatique, éco-anxiété, adhésion aux politiques publiques…). Ces enquêtes permettent de suivre l’évolution des comportements et d’identifier les freins ou les opportunités pour agir.

Every year, the statistical service of the General Commissariat for Sustainable Development publishes studies to better understand how French people relate to the environment. Two complementary barometers allow observation of underlying trends and recent developments: one focuses on concrete practices (daily habits, equipment, consumption), the other on opinions (perceptions of climate change, eco-anxiety, support for public policies, etc.). These surveys track behavior change and identify barriers or opportunities for action.

French Environmental Practices
Daily Actions
Recycling, heating, food, transportation, and more: an annual survey analyzes daily environmental practices.
Behavior Change
Results show gradual shifts in behavior and strong awareness of the most effective actions.
French Opinion on Environment
Ecology-Environment Barometer
Since 2023, the BEE (Barometer for Ecology and Environment), produced with Sciences Po, tracks the evolution of French public opinion on major environmental issues annually.
Environmental Concerns in 2025
In 2025, the environmental problems causing the most concern are global warming, natural disasters, and water pollution. The disappearance of certain plant or animal species is cited by only 10% of French people, despite scientific warnings on this subject (Source: SDES, Environmental Report 2025).
Risk Perception
According to a study by the Nuclear Safety and Radiation Protection Authority, more than two in three French people view pesticides and flooding as a high or very high risk to the population. Concerns about flooding, heatwaves, and wildfires have risen significantly in recent years. However, fears about nuclear plants and radioactive waste have declined compared to 2018 (Source: SDES, Environmental Report 2025).
