In the context of contemporary environmental challenges, Italian universities are strengthening their commitment to promoting a culture of energy sustainability, not only within their own campuses, but also through active participation in external initiatives of national importance. In this context, universities adhere to public campaigns and events - such as the National Energy Saving Day “M'illumino di Meno” (I use less light) - with the aim of contributing to the dissemination of good practices, raising public awareness on the conscious use of resources and strengthening dialogue with civil society. These awareness-raising strategies take the form of symbolic actions, cultural events, training activities and moments of confrontation involving students, teachers, technical-administrative staff and citizens, with a view to collaboration and shared responsibility towards the ecological transition.
