The Sustainable Lighting International Conference (SLIC) was held on the 10th and 11th of October 2025, bringing together researchers, professionals, and students to discuss the future of sustainable lighting.

The first day featured keynote lectures by Kerem Asfuroglu and Jordi Rocasalbas, alongside presentations from authors from various countries and disciplines. Discussions focused on light pollution mitigation, energy efficiency, ecological awareness, and the cultural dimensions of night-time environments.

The second day offered a series of social and cultural activities. Participants discovered the city of Aveiro through guided experiences and, later, visited the village of Álvaro, Oleiros, part of the Schist Villages, which is a network that is certified as a “Startlight Tourism Destination”. Here, a night-sky observation activity took place, in collaboration with Dark Sky Alqueva, highlighting the value of preserving natural nightscapes and raising awareness about light pollution.
