Theorising environmental justice: the expanding sphere of a discourse

Environmental justice has been a central concern in a range of disciplines, and both the concept and its coverage have expanded substantially in the past two decades. I examine this development in three key ways. First, I explore how early work on environmental justice pushed beyond many boundaries: it challenged the very notion of environment', examined the construction of injustice beyond inequity, and illustrated the potential of pluralistic conceptions of social justice. More recently, there has been a spatial expansion of the use of the term, horizontally into a broader range of issues, vertically into examinations of the global nature of environmental injustices, and conceptually to the human relationship with the non-human world. Further, I argue that recent extensions of the environmental justice frame move the discourse into a new realm where environment and nature are understood to create the conditions for social justice.
