By the end of this section, you should be able to:

  • Identify the major statutes governing environmental protection in India and the United States

  • Describe the roles of key regulatory agencies such as the EPA (US), CPCB, and NGT (India)
  • Distinguish between pollution control law, conservation law, and procedural environmental law (EIA)
  • Apply core doctrines — public trust, precautionary principle, polluter pays — to fact patterns
  • Trace how international treaties such as the Paris Agreement and UNFCCC shape domestic legislation
  • Connect landmark cases like M.C. Mehta v. Union of India and Massachusetts v. EPA to broader legal principles

Quick Answer

Environmental law is the body of statutes, regulations, and judicial decisions that govern how human activity affects the natural world. In India, the field rests on constitutional foundations (Articles 21, 48A, 51A(g)), umbrella legislation like the Environment (Protection) Act 1986, and specialized acts covering air, water, forests, and wildlife. In the United States, landmark statutes — the Clean Air Act, Clean Water Act, National Environmental Policy Act (NEPA), and Endangered Species Act — create a federal framework enforced by the EPA. Both systems rely on regulatory agencies, environmental impact assessment, and courts to balance economic development against ecological protection.
