Universities hold a crucial responsibility and role to contribute to sustainable development, also in their education task. The concept of competencies for sustainable development and the idea of using real-world sustainability issues in education are promising approaches to transform sustainability programmes at universities into student-centred learning environments. Especially the educational formats of problem-based learning and project-based learning foster such a process of educational innovation towards student-centred learning. Moreover, hybrid forms of problem-based and project-based learning offer added value, but challenges for PPBL courses in sustainability remain salient.
