Book excerpt: The National Environmental Policy Act (NEPA) introduced the environmental impact statement, transformed decision making by federal agencies, and spurred the growth of an extensive body of environmental law. This book takes a close look at the litigation of NEPA cases, including jurisdiction and related issues, standard and scope of judicial review, and the specific concerns of litigators. It identifies key NEPA issues and offers solutions to the challenges faced in practice, including climate change and its relationship to the NEPA process.
