Sustainable development in a post-Brundtland world

Not yet two decades after the publication of Our Common Future, the world's political and environmental landscape has changed significantly. Nonetheless, we argue that the concept and practice of sustainable development (SD)-as guiding institutional principle, as concrete policy goal, and as focus of political struggle-remains salient in confronting the multiple challenges of this new global order. Yet how SD is conceptualized and practiced hinges crucially on: the willingness of scholars and practitioners to embrace a plurality of epistemological and normative perspectives on sustainability; the multiple interpretations and practices associated with the evolving concept of “development”; and efforts to open up a continuum of local-to-global public spaces to debate and enact a politics of sustainability. Embracing pluralism provides a way out of the ideological and epistemological straightjackets that deter more cohesive and politically effective interpretations of SD. Using pluralism as a starting point for the analysis and normative construction of sustainable development, we pay particular attention to how an amalgam of ideas from recent work in ecological economics, political ecology and the “development as freedom” literature might advance the SD debate beyond its post-Brundtland quagmire. Enhanced levels of ecological degradation, vast inequalities in economic opportunities both within and across societies, and a fractured set of institutional arrangements for global environmental governance all represent seemingly insurmountable obstacles to a move towards sustainability. While these obstacles are significant, we suggest how they might be overcome through a reinvigorated set of notions and practices associated with sustainable development, one that explicitly examines the linkages between sustainability policies and sustainability politics.
