Democratic deliberation for sustainability transformations: between constructiveness and disruption

The discourse on sustainability transformations moves beyond accommodationist, reformist framings of sustainability to imply a radical, systemic shift toward new sustainable trajectories. While democracy has been accorded a central role in sustainability governance of most kinds, this emphasis on systemic transformation, and the new context of existential ecological threat, prompt a reconsideration of the kind of democracy that would provide a political foundation for sustainability. Arguing that the politics of sustainability transformation inherently demand democratization – for both disruption (of established power structures) and normativity (in relation to the negotiated meaning of sustainability) – this article explores the potential of deliberation in particular to create these foundations. I contend that while the recent policy-oriented practice of deliberation has itself become overly accommodationist, the concept can equally encompass a more disruptive, yet still normatively driven form, the time for which might be just right.
