The Ecological Transition School network was established in 2019 as an innovative response to contemporary social and environmental challenges. Its primary goal is to provide free training in manual trades related to ecological transition for young jobseekers aged 16 to 25. The ETRE Paris school, supported by the Keyrus Foundation, offers training in urban agriculture, eco-construction, and renewable energies. The Keyrus Foundation is deeply committed to ecology, inclusivity, and professional integration, sharing the same objectives for social and sustainable development as the ETRE schools.
