The current fossil fuel-based system of mobility is associated with a wide range of environmental and social problems. There is a growing body of literature on system innovations and transitions which has as a common understanding that long-term transformative change is necessary to deal with these complex problems. However, knowledge on the crucial role of citizen-consumers in sustainable mobility transitions is still underdeveloped. By incorporating the viewpoint of consumption patterns and everyday life routines, this book provides (new) knowledge on the role of citizen-consumers in sustainable mobility transitions. Theoretically, a practice based approach is developed as a novel framework to analyse, understand and influence transition processes to sustainable mobility at the level of everyday life. The focus in each of the three cases studies is on situated interactions between consumers and producers. Amongst these is an analysis of the role environmental information and subsidies in new car purchasing. Also, various examples in which an attempt was made to orchestrate a (modal) shift in commuting practices are examined. Each of the empirical case studies shows the important role of contextual factors in understanding and influencing mobility behaviour of citizen-consumers. In addition, this book helps to understand how and why innovation in mobility practices takes place or not.
