Sustainability Week is the largest student run sustainability programme in Switzerland. Now in its fourth year, it is organised by over 60 students from 5 universities with over 55,000 students in Zurich, ETH, Universitat Zurich, PHZH and Zurich University of the Arts. Over the past few years it has organised over 120 events with the aim of reaching and information as many students as possible on campus and around the city. The event also has the goal of setting concrete sustainability demands to the individual universities and connecting the five universities further around these topics. All events are open to the public and free of charge.
