This article both synthesizes and critically evaluates a now large, multi-disciplinary body of published research that examines the neoliberalization of environmental regulation, management, and governance. Since the late 1970s, neoliberal ideas and ideals have gradually made their way into the domain of environmental policy as part of a wider change in the global political economy. While the volume of empirical research is now such that we can draw some conclusions about this policy shift, the fact that the research has evolved piecemeal across so many different disciplines has made identifying points of similarity and difference in the findings more difficult. After clarifying what neoliberalism is and explaining why the term 'neoliberalization' is preferable, the article analyzes the principal components and enumerates the social and environmental effects of this multifaceted process. By offering a comprehensive and probing survey of the salient literature, I hope not only to codify the existing research but also to guide future critical inquiries into neoliberal environmental policy.
