This chapter introduces the central focus of Consumption Corridors: the perspective of the good life as a starting point for thinking about how we, as individuals and as societies, can live well within limits in an increasingly inequitable and ecologically stressed world. This, the authors argue, is the core challenge of our time. Consequently, the chapter invites the reader to explore the vision of a good life for all, living now and in the future. It then introduces consumption corridors as a means for the joint pursuit of this vision and as a compelling vehicle to sustainability.
