Environmental Policy & Law in India is a comprehensive framework of Acts, Rules, Notifications, and Constitutional Provisions designed to protect and improve the natural environment. The modern legal structure originated largely after the United Nations Conference on the Human Environment in Stockholm in 1972, which prompted India to enact comprehensive legislation. This framework was created to address the growing problem of pollution and the need to balance economic development with ecological sustainability.
The core of this law is the Environment (Protection) Act, 1986 (EPA), an umbrella legislation enacted following the Bhopal Gas Tragedy of 1984, which exposed the gaps in existing laws like the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981. The EPA, under Section 3, grants the Central Government broad powers to take all necessary measures to protect and improve the environment, including setting standards for emissions and regulating the handling of hazardous substances.
This body of law is deeply connected to the Constitution of India, specifically Article 48A (Directive Principles of State Policy), which mandates the State to protect and improve the environment, and Article 51A(g) (Fundamental Duties), which obligates every citizen to protect and improve the natural environment. Furthermore, the Supreme Court, in cases like M.C. Mehta v. Union of India (1987) (the Oleum Gas Leak Case), established the principle of absolute liability for industries engaged in hazardous activities and interpreted the Right to Life under Article 21 to include the right to a clean environment. The judiciary also established the 'Polluter Pays' and 'Precautionary' principles as integral to Indian environmental jurisprudence.
Key institutions connected to this law include the Central Pollution Control Board (CPCB) and the State Pollution Control Boards (SPCBs), which implement the Water and Air Acts, and the National Green Tribunal (NGT), established in 2010, which has jurisdiction over all civil cases involving substantial environmental questions.
Recently, the framework has seen significant changes, including the decriminalisation of most environmental laws in 2023, where sections imposing potential imprisonment were replaced by increased financial penalties to facilitate the ease of doing business. Additionally, the Forest (Conservation) Act and the Biological Diversity Act were amended in 2023. The Control of Air/Water Pollution (Grant, Refusal or Cancellation of Consent) Amendment Guidelines, 2026, introduced a new permitting philosophy where consent, once granted, remains valid until cancelled, replacing the previous system of periodic renewal.
