The discourse of 'green growth' has recently gained ground in environmental governance deliberations and policy proposals. It is presented as a fresh and innovative agenda centred on the deployment of engineering sophistication, managerial acumen and market mechanisms to redress the environmental and social derelictions of the existing development model.But the green growth project is deeply inadequate, whether assessed against criteria of social justice or the achievement of sustainable economic life upon a materially finite planet. This volume outlines three main lines of critique. First, it traces the development of the green growth discourse qua ideology. It asks: what explains modern society's investment in it, why has it emerged as a master concept in the contemporary conjuncture, and what social forces does it serve? Second, it unpicks and explains the contradictions within a series of prominent green growth projects. Finally, it weighs up the merits and demerits of alternative strategies and policies, asking the vital question: 'if not green growth, then what?'
