The Sustainable Consumption Research and Action Initiative (SCORAI) has, with financial support from the V. K. Rasmussen Foundation, been sponsoring a year-long colloquium on social change and sustainable consumption. This book is the capstone of this multifaceted project and brings together leading interdisciplinary experts on these developments and aims to provide a systematic understanding of the challenges and opportunities created by these new arrangements for provisioning goods and services, deriving and expressing personal identity, and engaging in processes of social and cultural communication.
