Climate change and rational use of energy ressources are two main issues that we intend to discuss with our pupils through that project. Our aim is to rase awareness among pupils so that we change their ideas, attitude and every day habits and create at last a sustainable school, with ecostudents, who treat the environment the way it should be treated to the benefit of all our kind. Our topics are: sustainable school, citizenship, climate change, conservation of resources , waste prevention and management, nutrition, mobility, biodiversity and governance, exchange of practices with partner schools
