In a sometimes difficult school climate, the schools express the need to develop a strategy to raise awareness of European citizenship for pupils. The training of eco-delegates, the creation of decision-making structures and the participation of everyone will enable pupils to take responsibility, enrich their thinking and become actors in an innovative European project. Moreover, this project is part of an inter-degree approach with the aim of setting up common practices between schools, i.e. promoting pedagogical innovation, enhancing the use of digital tools and using modern means of communication. From the start of the 2020 school year, in the context of Education for Sustainable Development, each structure will organise a council of ecodelegates, elected by their peers, who will have to take decisions and present their conclusions to school, administrative and eco-citizen councils at European level.
