In the industrialized world, Internet use has grown exponentially to become a global communication and business resource. For the time being, both theoretical and empirical research on consumption and the Internet are still in their infancy. This paper discusses the possible influence of the Internet on sustainable consumption. In absence of a solid empirical data base, the approach is a conceptual one. The paper investigates the role of the Internet in the development of consumption patterns and lifestyles, looks at the Internet as role in developing public awareness of environmental and social issues, and discusses its potential contribution to support strategies for sustainable consumption such as sufficiency, efficiency, consistency, and political consumption. It concludes with implications for consumer policy and questions for further research.
