Sustainability is both a contested concept and a social movement of our time. It has different meanings for different people, and is used in a wide variety of contexts, not least in relation to organizations including business. Sustainability is increasingly tied to other concepts such as corporate accountability, responsibility and citizenship. These concepts direct attention to the implication of organizations in wider environmental, social and political as well as economic systems. Business, in particular, is positioned as a key source o f problems relating to global unsustainability, and managers of all types of organizations are being tasked with the resolution of such problems.
