In this paper, we address the issue of teaching a subject, sustainability, that ideally should permeate the whole engineering education, but at the moment often plays a minor role in the curriculum. Here we discuss the tactics of planning and conducting a sustainability course with the explicit goal of truly engaging the students and making an impact on their thinking. Furthermore, we here present a framework that can be used in course planning and analysis. Finally, we discuss how this framework was used in our sustainability course for Media Technology engineering students at KTH Royal Institute of Technology, and the engagement and resulting change in students perception of sustainability. Moreover, we argue that beyond rethinking the engineer and the engineering education, we also need to rethink our roles as university teachers.
