Sustainability Week is a periodic week of interesting activities and events, each time focusing on a different sustainability-related theme. The goal is to raise awareness on a specific topic, foster students’ participation, and ultimately help students to critically reflect on their own behaviors. The extracurricular activities are wide-ranging (presentations, conferences, film screening, visits, competitions... etc.), and take place in a convivial and thoughts-sharing atmosphere.

Previous Sustainability Weeks have been held on the topics of 'Food for Thought' and 'Green Couture'.
