Development of Environmental Law in India: Pre-Stockholm Foundations and Post-Stockholm Growth

Indian environmental law did not begin in 1972, but 1972 changed it. Before the Stockholm Conference, environmental concerns were expressed through religious ethics, royal edicts, colonial nuisance and forest laws, and a handful of post-independence statutes enacted for other purposes. After Stockholm, India built a dedicated body of environmental legislation, a constitutional mandate, specialised institutions and, through its courts, a set of principles that are now among the most developed in the world. This topic traces that development in six eras.

1. The Ancient Period: An Ethic of Reverence

Ancient Indian thought did not separate humanity from nature. The Vedas personify natural forces as deities: Prithvi (earth), Varuna (water), Vayu (air), Agni (fire) and Surya (sun). The Prithvi Sukta of the Atharva Veda (Book 12) is an extended hymn to the earth, containing the line 'Mata bhumih putro aham prithivyah' (the earth is my mother and I am her son). The Isha Upanishad opens with the idea that everything in the universe is pervaded by the divine and should be enjoyed with renunciation, not greed.

These ideas carried practical rules. The Manusmriti prescribed fines for injuring trees in proportion to their usefulness. Kautilya's Arthashastra provided for a superintendent of forest produce, forest reserves in which animals were protected (abhayaranya), and graded fines for cutting sprouts, branches and trees in city parks. The Buddhist and Jain traditions extended the principle of ahimsa (non-violence) to all living beings.

The clearest State measure of the period is Emperor Ashoka's Fifth Pillar Edict (third century BCE), which listed creatures that were not to be killed, restricted killing on specified days, and forbade the burning of forests without reason or in order to kill living beings. It is often described as one of the earliest recorded pieces of wildlife legislation.

2. The Medieval Period

Environmental regulation in the medieval period was incidental. Rulers laid out gardens, canals and tanks, and maintained royal hunting reserves (shikargahs) in which game was protected for the ruler's sport rather than for its own sake. Forests remained largely under the customary control of local communities. There was no body of law directed at environmental protection as such.

3. The British Period: Revenue before Ecology

British rule brought the first systematic legislation touching the environment, but for purposes that were commercial, sanitary or administrative. Two strands can be distinguished.

3.1 The forest strand

The demand for timber for railway sleepers and shipbuilding led to rapid deforestation in the first half of the nineteenth century. The colonial response was to assert State control over forests. A Forest Department was created in 1864 with Dietrich Brandis as the first Inspector General of Forests, followed by the Indian Forest Acts of 1865 and 1878 and the National Forest Policy of 1894. The Indian Forest Act, 1927, which is still in force, consolidated this law. Its object was the regulation of timber and forest revenue, and its effect was to curtail the customary rights of forest-dwelling communities, a grievance that the Forest Rights Act, 2006 would address eighty years later.

3.2 The nuisance and public health strand

A second group of laws dealt with nuisances affecting public health and convenience in the growing presidency towns:

• Shore Nuisance (Bombay and Kolaba) Act, 1853, often cited as the earliest pollution-related law, for the removal of nuisances below the high-water mark.
• Oriental Gas Company Act, 1857, penalising the fouling of water by a gas company.
• Indian Penal Code, 1860: public nuisance, fouling the water of a public spring or reservoir, and making the atmosphere noxious to health (Sections 268, 277 and 278).
• Northern India Canal and Drainage Act, 1873 and Obstructions in Fairways Act, 1881, regulating canals and waterways.
• Indian Easements Act, 1882, recognising natural rights to air and water flowing to one's land.
• Indian Fisheries Act, 1897, prohibiting the use of poison and explosives to kill fish.
• Code of Criminal Procedure, 1898, Section 133: the Magistrate's conditional order for removal of public nuisance.
• Indian Ports Act, 1908, prohibiting the discharge of ballast and oil into ports.
• Bengal Smoke Nuisances Act, 1905 and Bombay Smoke Nuisances Act, 1912, controlling smoke from furnaces.
• Elephants' Preservation Act, 1879 and Wild Birds and Animals Protection Act, 1912, giving limited protection to wildlife.

The Government of India Act, 1935 placed water, forests, fisheries and public health in the provincial list, a distribution largely carried into the Constitution and one reason why Parliament later needed Articles 252 and 253 to legislate on the environment.

4. Independence to Stockholm (1947 to 1972): Development First

The Constitution of 1950 contained no express reference to the environment. The priority of the new State was economic development through the Five-Year Plans, and environmental concerns appeared only incidentally in laws enacted for other purposes:

• Factories Act, 1948, with provisions on the disposal of wastes and effluents inside factories.
• National Forest Policy, 1952, which set the goal of one-third of the land area under forest; and the Indian Board for Wild Life, constituted in 1952.
• River Boards Act, 1956, for the regulation and development of inter-State rivers.
• Merchant Shipping Act, 1958, with provisions on pollution from ships.
• Ancient Monuments and Archaeological Sites and Remains Act, 1958.
• Prevention of Cruelty to Animals Act, 1960.
• Atomic Energy Act, 1962, regulating radioactive substances (replaced by the SHANTI Act, 2025).
• Insecticides Act, 1968, regulating the manufacture, sale and use of insecticides.

Environmental disputes in this period were decided under the law of nuisance, the Indian Penal Code and Section 133 of the Code of Criminal Procedure. There was no pollution control authority, no environmental standard of general application and no environment ministry.

5. The Stockholm Conference, 1972: The Turning Point

The United Nations Conference on the Human Environment met at Stockholm from 5 to 16 June 1972. It adopted the Stockholm Declaration of 26 principles and an action plan, and led to the creation of the United Nations Environment Programme. The opening day, 5 June, is observed as World Environment Day.

India's Prime Minister, Indira Gandhi, was the only head of government other than the host to address the Conference. Her speech linked environmental degradation with poverty, asking whether poverty and need were not the greatest polluters. The speech set the theme that has defined India's position ever since: environmental protection must go hand in hand with development and the removal of poverty.

Institutionally, India had set up a National Committee on Environmental Planning and Co-ordination in 1972. On the recommendation of the Tiwari Committee, a Department of Environment was created in 1980, which became the Ministry of Environment and Forests in 1985 and was renamed the Ministry of Environment, Forest and Climate Change in 2014.

6. Post-Stockholm Development

The development after 1972 falls into four phases, each triggered by a different force: international commitment, industrial disaster, judicial activism and, most recently, institution-building and climate change.

6.1 Phase one (1972 to 1984): the legislative foundation

Within a decade India enacted the core of its environmental legislation. The Wild Life (Protection) Act, 1972 established protected areas and schedules of protected species, and Project Tiger followed in 1973. The Water (Prevention and Control of Pollution) Act, 1974, enacted under Article 252, created the Central and State Pollution Control Boards and a consent regime for discharges. The Constitution (Forty-second Amendment) Act, 1976 inserted Articles 48A and 51A(g) and moved forests and wildlife to the Concurrent List. The Forest (Conservation) Act, 1980 required central approval for the diversion of forest land, and the Air (Prevention and Control of Pollution) Act, 1981, enacted under Article 253, extended the pollution control model to air.

6.2 Phase two (1984 to 1991): Bhopal and the judicial awakening

On the night of 2 and 3 December 1984, methyl isocyanate gas escaped from the Union Carbide pesticide plant at Bhopal, killing thousands and injuring hundreds of thousands. The disaster exposed three gaps: there was no general environmental law, no regime for hazardous industries, and no effective mechanism for compensating mass victims. The response was swift:

1. Bhopal Gas Leak Disaster (Processing of Claims) Act, 1985, making the Union of India the sole representative of the victims.
2. Environment (Protection) Act, 1986, the umbrella statute, enacted under Article 253.
3. Factories (Amendment) Act, 1987, inserting Chapter IVA on hazardous processes.
4. Amendments in 1987 and 1988 to the Air and Water Acts, adding noise to the definition of air pollutant and giving the Boards power to issue closure directions.
5. Public Liability Insurance Act, 1991, providing compulsory insurance and no-fault relief.

The courts moved at the same time. Public interest litigation, developed in the early 1980s, became the principal vehicle of environmental protection, and in 1987 the Supreme Court laid down the rule of absolute liability.

6.3 Phase three (1991 to 2006): liberalisation and judge-made principles

Economic liberalisation after 1991 increased industrial and infrastructure activity, and with it the demand for preventive controls. The Coastal Regulation Zone Notification, 1991 and the first Environmental Impact Assessment Notification, 1994 introduced preventive regulation. Two specialised bodies were created, the National Environment Tribunal (1995, never brought into force) and the National Environment Appellate Authority (1997).

This was also the period in which the Supreme Court declared the principles that now define the subject: polluter pays (Indian Council for Enviro-Legal Action, 1996), sustainable development and the precautionary principle (Vellore, 1996), the dictionary meaning of 'forest' and continuing mandamus (T.N. Godavarman, 1996 onwards) and the public trust doctrine (M.C. Mehta v. Kamal Nath, 1997). Parliament enacted the Biological Diversity Act, 2002, and in 2006 the National Environment Policy, the EIA Notification, 2006 and the Forest Rights Act, 2006 were adopted.

6.4 Phase four (2006 onwards): institutions and climate

The most recent phase is marked by specialised institutions and the arrival of climate change on the legal agenda. The National Action Plan on Climate Change (2008) launched eight national missions. The National Green Tribunal Act, 2010 created a specialised environmental court. The Compensatory Afforestation Fund Act, 2016 gave statutory form to the funds collected for forest diversion, and a new generation of waste management rules followed in 2016, with further rules for electronic and battery waste in 2022 and new Solid Waste Management Rules in 2026. The Commission for Air Quality Management Act, 2021 created a dedicated body for the National Capital Region.

Recent years have seen a shift in the enforcement model. The Energy Conservation (Amendment) Act, 2022 enabled a carbon credit trading scheme. The Jan Vishwas (Amendment of Provisions) Act, 2023 and the Water (Prevention and Control of Pollution) Amendment Act, 2024 replaced imprisonment for most contraventions with monetary penalties. In 2023 the Forest (Conservation) Act was amended and renamed, and the Biological Diversity Act was amended. In 2024 the Supreme Court recognised a right against the adverse effects of climate change (M.K. Ranjitsinh v. Union of India).

7. The Six Eras at a Glance

8. Critical Appraisal

The development of Indian environmental law has been reactive rather than planned. Its major statutes followed an international conference and an industrial disaster, and many of its central principles were declared by courts in response to specific crises rather than enacted by Parliament. The result is a body of law that is rich in principle but uneven in enforcement. The recent turn towards monetary penalties, post-facto clearances and market instruments reflects a new emphasis on ease of doing business, and whether it strengthens or weakens environmental protection is the central question of the present phase.
