This document discusses the difficulties in defining environmental law. It notes that there is no universally agreed upon definition, and scholars have different perspectives. One view is that environmental law consists of statutes, regulations, and case law related to environmental protection in a given jurisdiction. However, this has problems, as environmental issues involve more than just legal instruments. A broader view is that environmental law aims to achieve environmental policy goals through legal means. The document examines these different approaches and their limitations in comprehensively capturing the field of environmental law.
