The local schools have developed and set up educational programs regarding environmental issues and their sustainability. These programs can be attended on a voluntary basis and are scheduled to impact at least 20% of students.

A Whole plan !

International Program for Environmental Education and Sustainable Development (EESD), Eco-School is a label for primary and middle schools, colleges and high schools to promote environmentally friendly behavior and integrate the EESD in teachings. In volunteering establishments, pupils, teachers, management and staff, work, in turn, on six major themes : food, biodiversity, waste, water, energy and solidarity. In partnership with local authorities, local associations and parents’ associations, schools have analyzed their living place focusing on the chosen theme and the progressive improvement through the action plan they made.
