This paper attempts to bridge business ethics to corporate social responsibility including the social and environmental dimensions. The objective of the paper is to suggest a conceptual methodology with which ethics of corporate environmental management tools can be considered. The method includes two stages that are required for a shift away from the current dominant unsustainable paradigm and toward a more sustainable paradigm. The first stage is paradigmatic, metaphoric and normative. The second stage is a practical stage, which in turn, (...) is analytic, descriptive and positive. The method is applied to common industrial metabolism tools of ecological footprints (EF), environmental life cycle assessment (LCA) and industrial ecology (IE). The application shows that all three tools can be used in business ethics, in particular, when the first stage of the method is applied to their use. (shrink)
