French Ministry of Ecological Transition (Ministère de la Transition écologique)

The French Ministry of Ecological Transition (Ministère de la Transition écologique) is a department of the French government responsible for national policy related to climate, sustainable development, biodiversity, energy transition, pollution prevention, transport, housing, and environmental regulation. Established in 1971 as the Ministry of the Environment, it has evolved into France’s principal authority for ecological transition and climate policy. Headquartered in Paris, the ministry oversees major regulatory frameworks including RE2020, energy efficiency policies, and decarbonisation initiatives, while coordinating with agencies such as CEREMA, ADEME, CSTB, and the French Office for Biodiversity.
