This book assesses the recent growth and future prospects of private transnational environmental certification and standards regimes. Regimes of this type have proliferated in the last 20 years as businesses and environmental groups have sought to replace, or improve upon, traditional inter-governmental conventions and treaties. Recent theory and research suggest that these regimes transfer the environmental standards and norms of West Europe and North America outward, via trade and investment, to developing states worldwide. This book challenges this literature and examines in detail to what degree, and under what circumstances do these transnational regimes truly influence industrial environmental practices in developing countries.
