Public libraries as third places play a crucial role in promoting digital literacy in Quebec. With the emerging concept of "eco-digital literacy," this project highlights that environmental issues related to digital technologies and AI are a central dimension of digital literacy. In this perspective, the project proposes to organize ten pilot workshops of citizen conversations in public libraries in 2024-2025 on this theme. These workshops will mobilize prospective scenarios on digital sobriety in Quebec by 2050 to stimulate exchanges and reflections. Drawing on a proven methodology of participatory foresight, these workshops will aim to disseminate knowledge developed within Obvia's Digital Sobriety Research Axis to a broad audience. At the conclusion of these workshops, an activity report with recommendations will be produced. Moreover, this project could lead to a longer-term partnership between public libraries in Quebec and Obvia.
