There is an emerging recognition of the importance of consumption within the sustainability debate. The term ′sustainable consumption′ has been coined to reflect this emphasis. In pursuit of its advocacy remit, the Sustainable Development Commission is currently seeking to influence government policy on sustainable consumption, specifically with regard to DEFRA′s forthcoming Sustainable Consumption and Production strategy and other UK policy developments. The purpose of this document is to enhance that process. It aims to provide a guide to the complexity of the sustainable consumption debate, an overview of the extensive literatures on consumer behaviour and lifestyle change, and an analysis of the policy opportunities suggested by these literatures.
