Book excerpt: Green Gentrification looks at the social consequences of urban "greening" from an environmental justice and sustainable development perspective. Through a comparative examination of five cases of urban greening in Brooklyn, New York, it demonstrates that such initiatives, while positive for the environment, tend to increase inequality and thus undermine the social pillar of sustainable development. Although greening is ostensibly intended to improve environmental conditions in neighborhoods, it generates green gentrification that pushes out the working-class, and people of color, and attracts white, wealthier in-migrants. Simply put, urban greening "richens and whitens," remaking the city for the sustainability class. Without equity-oriented public policy intervention, urban greening is negatively redistributive in global cities. This book argues that environmental injustice outcomes are not inevitable. Early public policy interventions aimed at neighborhood stabilization can create more just sustainability outcomes. It highlights the negative social consequences of green growth coalition efforts to green the global city, and suggests policy choices to address them. The book applies the lessons learned from green gentrification in Brooklyn to urban greening initiatives globally. It offers comparison with other greening global cities. This is a timely and original book for all those studying environmental justice, urban planning, environmental sociology, and sustainable development as well as urban environmental activists, city planners and policy makers interested in issues of urban greening and gentrification.
