In this course the social debate and current social scientific research on sustainability issues are of central importance. Social-ecological issues are approached at different analytical levels. Topics that are discussed include, for example, environmentally significant behavior, social influence and nudging, the rise of new social movement organizations that focus on sustainable consumption practices, corporate social responsibility, and urban sustainability. Sustainability issues are further approached from both a social-historical, normative, and future oriented perspective (cf. e.g. the multi level perspective (MLP), the social practice approach, transition management (TM), and the potential activating role of ‘fictions’ or imaginaries). Next to the identification of different levels, actors and factors in the context of change processes toward a sustainable society, recent insights stemming from transition studies are coupled to some contemporary sociological and social theories. Finally, different case studies will be explored in depth and guest speakers are invited to talk about topics such as global warming, peak oil, green washing, and/or other related and current sustainability issues.
