This paper is an application of Heidegger’s work to issues in sustainability and environmental justice that demonstrates the value and significance of his work beyond traditional contexts for analysis of his thinking. It argues that Heidegger prompts a constructive environmental phenomenology, which is developed around three themes: physics and teleology; dwelling in nature; and the social obligations of the sciences. Aristotle’s Physics is shown to provide Heidegger with a teleological conception of nature that promotes its intrinsic value. This analysis is used toward an environmental ethics of “dwelling,” in contrast to consumer culture’s reduction of nature to resource. Finally, Heidegger’s potential contribution to debates concerning the social obligations of the sciences is developed. Throughout these analyses, his work is connected with principles of deep ecology, social ecology and ecofeminism, and his applicability to environmental issues in international development is demonstrated. In conclusion, Heideggerian ecophenomenology is argued to promote sustainability and environmental justice insofar as it supports an alternative to the logic of domination currently overrunning the globe.
