The book identifies the emergence and increasing political importance of ‘ecological modernization’ as a new language in environmental politics. In this conceptual language, environmental management appears as a ‘positive sum game’. Combining social theory with detailed empirical analysis, the book illustrates the social and political dynamics of ecological modernization through a study of the acid rain controversies in Great Britain and the Netherlands. The book concludes with a reflection on the institutional challenge of environmental politics in the years to come. The book is not only seen as a ‘modern classic’ in the literature on environmental politics but is also renowned for its application of discourse analysis to the study of the policy process.
