How can we act concretely to meet the enormous environmental challenge facing us? How can we reduce our carbon footprint and provoke this approach with as many people as possible? Our approach is based on the concept of ecological challenges, takes the form of artistic productions staging these challenges and is assessed by the carbon footprint measured individually and collectively for the participants in the project. This story will have for scenario a group of young Europeans who meet for the first time through social networks and who will try to take up ecological challenges to reduce their carbon footprint. In the end, through this project our students, the active adults of the project but also the entire network of the project will feel more European thanks to strengthened linguistic and communication skills but also thanks to their civic engagement in the service of a fundamental common environmental cause for everyone's future.
