The project is based on training our students to become active eco-delegates in the fight against the loss of biodiversity. The general context is defined by the Green Pact which makes the EU economy sustainable by ensuring a fair and inclusive transition. Our activities for the next two years will revolve around 4 themes: urban biodiversity, biodiversity at school, biodiversity and food production, and finally the protection of biodiversity in a national park. We believe that it is essential to anchor the environmental transition in school learning through exchanges and, in particular, exchanges of good practices.
