This study examined the impact of a procedure implemented and used at one Swedish university to promote integration of the concept of sustainability into courses. The study is based on a literature study and a case study at the University of Gavle in Sweden, where faculty members are asked to classify their courses and research funding applications regarding the contributions thereof to sustainable development. The results of the study indicated that this procedure can indeed stimulate faculty members to integrate sustainable development in their courses. It is clear that the reported changes in courses were also influenced by other factors such as the increased general awareness of environmental issues.
