Understanding environmental law and policy is crucial for all professionals interfacing with our environment, not just for attorneys. Environmental Law for Non-Lawyers, 6th Edition continues its 40-year tradition of demystifying the processes by which we make the law, influence its creation, and operate within its framework. The entire text was updated in 2025 to include major recent Supreme Court decisions, agency rulemaking, and executive orders – as well as new international frameworks for tackling global environmental issues. The text is written to provide a concise understanding of each major environmental topic, from appropriating water to the strictures of Superfund sites. It can be used in graduate courses, as well as at the upper-division undergraduate level. The book is equally at home on the reference shelf of engineers, conservationists, and policymakers.
