The BRIGHTS project (2021-1-IT02-KA220-HED-000030264) has published its guidelines on Innovative Teaching Methodologies for Sustaianbility Education, highlighting the critical importance of implementing innovative approaches across European universities. The project partners collaboratively developed these guidelines, analyzing data obtained from a comprehensive questionnaire distributed among various EU member states, and subsequently through a workshop held at the University of Pavia. The combined research methodology allowed for obtaining a holistic view of current teaching practices, evaluating readiness for innovation, and identifying major challenges, obstacles, and opportunities within European higher education institutions.
