This book focuses on such questions and the complexities involved in answering them. It explores the diversity of ways in which environment and social difference are intertwined and how the justice of their interrelationship matters. It has a distinctive international perspective, tracing how the discourse of environmental justice has moved around the world and across scales to include global concerns, and examining research, activism and policy development in the US, the UK, South Africa and other countries. The widening scope and diversity of what has been positioned within an environmental justice ‘frame’ is also reflected in chapters that focus on waste, air quality, flooding, urban greenspace and climate change. In each case, the basis for evidence of inequalities in impacts, vulnerabilities and responsibilities is examined, asking questions about the knowledge that is produced, the assumptions involved and the concepts of justice that are being deployed in both academic and political contexts. offers a wide ranging analysis of this rapidly evolving field, with compelling examples of the processes involved in producing inequalities and the challenges faced in advancing the interests of the disadvantaged. It provides a critical framework for understanding environmental justice in various spatial and political contexts, and will be of interest to those studying Environmental Studies, Geography, Politics and Sociology.
