Abstract The Environmental Justice Movement has provided policy makers with a set of principles that can, and should, inform public policy: Pollution prevention, the precautionary principle, and the idea of community self-determination. Each of these strands of environmental justice philosophy is drawn from earlier social movements, but has grown more sophisticated in its application in the environmental justice context. Using case studies of public policies based on—or in opposition to—these principles, I will set out what environmentally just public policy would look like.
