The concept of ethics in management clearly refers to the usual issues – not cheating customers, selling sub-standard products, neglecting to pay suppliers, and so forth. But here I will argue that it has a much wider scope since it takes place in a planetary context. This is different from the notion of globalization and refers to the larger planetary crisis in which we find ourselves – a crisis of many dimensions and which certainly includes issues such as climate change, collapsing resources, pollution and toxic elements in the environment and our bodies, loss of biodiversity on the environmental side, and social issues such as poverty, militarism and the arms trade, many forms of social exclusion and related injustices. Given that the corporate sector is the single biggest global actor, its ethical responsibilities are equally big. These might include such factors as commitment to environmentally safe energy systems and modes of transport, concern with what society and economy might look like as we enter the era of fossil fuel decline, commitment to “cradle to cradle” design in all contexts, and concern with the real social and environmental utility of products. The paper will explore these issues and attempt to link the issue of ethics and management to three major movements: concern with the creation of a social economy as a possible form of post-capitalist or post-industrial socio-economic order; to the field of development ethics as an important way of relating management and development; and the re-conceptualization of management as management for transition and sustainability as key elements in creating not only a desirable future, but any future at all in a situation where the future of our civilization is truly at risk
