Drawing on an empirical study of environmental policies in Manchester (UK) and Saint-Etienne (France), this article attempts to provide a periodization of the evolution of the management of urban environmental issues. The periodization traces the shift in discourse from a focus on ‘local environment’ to ‘sustainable urban development’. Three main sequences are identified corresponding to three different ways of tackling environmental issues covering a period from the late 1970s up to the present. The aim of this article is twofold. First, it will use environmental policies as a tool to understand the transformations of urban governance, and in particular the transformations of the actors involved in policy-making. Second, it will show how sustainable development policies are used by local elites to neutralize urban conflicts by excluding environmental grassroots movements from the management of environmental issues. Finally, the article will discuss how this marginalization should be considered as a sign of the emergence of a post-democratic era.
