Inspired by the ‘practice turn’ in consumption studies, this interdisciplinary book looks through the lens of social practice theory to explore important and timely questions about how to intervene in social life. It discusses a range of applied sustainability topics including energy consumption, housing provision, water demand, transport, climate change, curbside recycling and smart grids, seeking to redefine what intervention is, how it happens, and who or what can intervene to address the growing list of environmental calamities facing contemporary societies. These issues are explored through a range of specific case studies from Australia, the UK and the US, providing theoretical insights that are of international relevance. The book will be of interest to researchers and students in the fields of sociology, consumption studies, environmental studies, geography, and science and technology studies, as well as policy makers and practitioners seeking to intervene in social life for sustainability.
