Block 4 · Unit 12
Environmental Legislation
To protect humankind and other living beings from environmental problems, and to curtail activities affecting the environment negatively, numerous agreements have been signed among countries and legislations enacted at national level. This unit covers India's constitutional provisions, national Acts (Water, Air, Forest/Wildlife, General), international conventions (Stockholm to Paris), issues in enforcement, PIL case studies, and institutional arrangements (MoEFCC, CPCB).
🏛️
Section 12.1
Introduction & Constitutional Provisions
As human civilisation progressed, man started altering the natural environment in the pursuit of creating an economic, social and cultural environment of his own choice. This slowly resulted in depletion of natural resources and degradation of environment. Environmental problems are intrinsically global in nature — pollution does not observe political territories or legislative jurisdictions. Therefore, we need legislation at national level AND mutually beneficial agreements at international level.
India's Constitutional Provisions for Environmental Protection
🏛️ Ministry Timeline: Department of Environment established in India → 1980. Became Ministry of Environment and Forests → 1985. Renamed Ministry of Environment, Forest and Climate Change (MoEFCC) → May 2014. MoEFCC has overall responsibility for administering and enforcing environmental legislations and policies.

Section 12.2
National Legislations
Existing Indian environmental legislations can be grouped into four categories:
Four Categories of Indian Environmental Legislation
A. Water Acts
💧 Water (Prevention and Control of Pollution) Act, 1974 & Amendment 1988
The Act vests regulatory authority in State Pollution Control Boards (SPCBs) and empowers them to establish and enforce effluent standards for factories. A Central Board (CPCB) performs the same functions for Union Territories and coordinates activities among states. Key provisions:
SPCBs control sewage and industrial effluent discharges by approving, rejecting or conditioning applications for consent to discharge
SPCBs advise state governments on appropriate sites for new industry
Board has power of entry for examination, testing of equipment, and power to take water samples from any stream, well, or sewage
1988 Amendment: Board may now close a defaulting industrial plant or withdraw its supply of power or water by administrative order; penalties more stringent; citizen's suit provision added
Water Cess Act, 1977: Creates economic incentives for pollution control. Requires local authorities and certain designated industries to pay a cess (tax) for water consumption. Revenue used to implement the Water Act.
B. Air Acts
💨 Air (Prevention and Control of Pollution) Act, 1981 & Amendment 1987
Expanded authority of Central and State Boards (established under Water Act) to include air pollution control
States not having water pollution boards were required to set up air pollution boards
All industries in designated air pollution control areas must obtain a "consent" (permit) from State Boards
States must prescribe emission standards for industry and automobiles, consulting Central Board
Board has power of entry for examination, testing, and power to take air samples from any chimney, fly ash, or outlet
1987 Amendment: Boards may close defaulting plants or stop electricity/water supply. Board may apply to court to restrain emissions exceeding limits. Citizens suit provision introduced. Act extended to include noise pollution
C. Forest and Wildlife Acts
Act
Year
Key Provisions
Wild Life (Protection) Act
1972 + Amendment 1982
State wildlife advisory boards; regulations for hunting; establishment of sanctuaries and national parks; regulations for trade in wild animals; judicially imposed penalties. Schedule I (endangered — fully protected throughout India). Schedule II–IV (regulated via licensing). Schedule V (vermin — no restrictions). 1982: permits capture/transportation for scientific management of animal population
Forest (Conservation) Act
1980
Prior approval of Central Government required for diversion of forestlands for non-forest purposes. Advisory Committee advises Centre on approvals
Forest Act
1927 (colonial)
4 forest categories: Reserved forests, village forests, protected forests, private forests. Unauthorized felling, quarrying, grazing and hunting in reserved forests = punishable
Biodiversity Act
2000 (passed Dec 2002)
India = one of 12 mega-biodiversity countries. Party to CBD 1994. Three-tier structure: NBA (National Biodiversity Authority) + State Boards + Local Committees. NBA deals with all cases of access by foreigners. Opposes IP rights given in other countries on Indian biological resources
🦁 India's Conservation Projects: Hangul (1970) · Lion (1972) · Project Tiger (1973) · Crocodiles (1974) · Brown-antlered Deer (1981) · Project Elephant (1991–92). India is also a signatory to CITES (1976) — Convention on International Trade in Endangered Species.
D. General Acts (Most Important)
⚖️ Environment (Protection) Act, 1986 — The "Umbrella Legislation"
Enacted in the wake of the Bhopal tragedy. Designed as an "umbrella" legislation providing a framework for Central Government coordination of all central and state authorities. Defines environment to include water, air, land and the inter-relationships among them and with all living creatures, plants, micro-organisms and property.
Section 3(1): Empowers Centre to take all measures necessary for protecting and improving quality of environment — set national ambient standards, set emission/effluent standards, regulate industrial locations, prescribe hazardous substance procedures, establish safeguards preventing accidents
Central Government coordination: may lay down environmental quality standards, restrict locations of industries, handle hazardous substances, do environmental impact assessment
First legislation to give Central Government authority to issue direct orders to close, prohibit or regulate any industry, or stop supply of electricity, water, or any other service
Explicitly prohibits discharge of environmental pollutants exceeding prescribed standards
Specific prohibition against handling hazardous substances outside compliance with regulatory standards
Persons responsible for discharges exceeding standards must prevent/mitigate pollution AND report to governmental authorities
Penalties: fine or imprisonment or both. Any person (not just government officials) may file a complaint with a court

Section 12.2
Question
What are the main objectives of Environment Protection Act, 1986?
✅ Answer
The main objectives of the Environment (Protection) Act, 1986 are: protecting and improving the quality of the environment and preventing, controlling and abating environmental pollution. It is an "umbrella legislation" designed to provide a framework for Central Government coordination of all environmental authorities. It empowers the Central Government to: set national ambient quality standards and emission/effluent standards; regulate industrial locations; prescribe hazardous substance procedures; establish safeguards against accidents; collect and disseminate information on environmental pollution; and issue direct orders to close, prohibit or regulate any industry.
🌐
Section 12.3
International Conventions and Treaties
There is no international legislation body with authority to pass binding legislation globally. The international court at Hague has no power to enforce its decisions. International legislation depends on voluntary agreement of parties. Nations that agree = "Parties." Conventions provide a framework; each nation adopts its own national legislation to implement. Protocols are international agreements linked to existing conventions.

Section 12.4
Issues in Enforcement
Despite so many legislative measures, the state of environment in India continues to be gloomy. Levels of pollution still alarming. Delhi is one of the most polluted cities in the world (WHO). Key enforcement problems:
Key Problems in Enforcement of Environmental Legislation
Public Interest Litigation (PIL) — Role of Judiciary
Despite inadequacy of legislation, new decisions of courts (especially NGT) have generated hope. PIL has been a crucial tool in environmental protection. Notable examples:
Landmark PIL Cases in Environmental Protection in India
Mehta also campaigned for lead-free petrol in India's 4 largest cities (done); 250 towns near Ganga to install sewage treatment plants (SC ordered over 2,000 industries along Ganga to clean up or close); won SC decision forcing a fertiliser factory to compensate thousands sickened by 1985 gas leak.
🧠 Key Insight: Many environmental legislations are essentially "social code of conduct" that should automatically be part of better civic sense — not just a legal framework. Public awareness and environmental education can considerably reduce the need for multitudes of legislations. Enforcement under the Indian context will continue to be difficult in the foreseeable future.

📋 Unit 12 — Summary
India's Constitution has specific environmental provisions: Article 51A(g) (Fundamental Duty of every citizen — 42nd Amendment 1976) and Article 48A (Directive Principle of State Policy). MoEFCC = nodal agency for environmental legislation.
Four categories of national legislation: Water Acts (1974 Water Act + 1977 Cess Act), Air Acts (1981 Air Act), Forest & Wildlife Acts (1972 Wildlife Act, 1980 Forest Conservation Act, 2000 Biodiversity Act), General Acts (1986 EPA — umbrella legislation; 1995 National Environmental Tribunal; 2010 NGT).
Environment Protection Act 1986 is the "umbrella legislation" enacted after Bhopal tragedy. First to give Central Government authority to issue direct orders to close industries or stop utility supply.
NGT Act 2010: Established 18.10.2010. Principal seat: New Delhi. Four zonal benches: Bhopal, Pune, Kolkata, Chennai. Dispose cases within 6 months. Jurisdiction covers all environmental laws.
International legislation depends on voluntary agreement of parties. Key conventions: Stockholm (1972, → UNEP), Basel (1989, hazardous waste), Rio (1992, → UNFCCC + CBD + Agenda 21), Montreal Protocol (1987, ozone), Kyoto (1997), Paris Agreement (2015, limit to 2°C/1.5°C).
Enforcement problems: Legislation punitive not preventive; overlapping powers of authorities; vague statutes; no public participation; shortage of funds; public opposition.

Terminal Questions with Detailed Answers
Exam-style questions from the IGNOU textbook.
1
List the important categories of national legislations.
✅ Model Answer
The four important categories of national environmental legislations in India are:
Water Acts: Water (Prevention and Control of Pollution) Act, 1974 + Amendment 1988; Water (Prevention and Control of Pollution) Cess Act, 1977
Air Acts: Air (Prevention and Control of Pollution) Act, 1981 + Amendment 1987
General Acts: Environment (Protection) Act, 1986 (umbrella legislation); National Environmental Tribunal Act, 1995; National Green Tribunal Act, 2010
2
Analyse briefly the issues in the enforcement of environmental legislation in India.
✅ Model Answer
Punitive not preventive: Most legislation applies only AFTER pollution/damage occurs. Preventive measures rarely invoked — agencies act only after harm is done.
Overlapping powers: Multiple authorities with overlapping jurisdiction. A pollution control board may refuse NOC, but a municipality may still grant a license allowing the industry to operate.
Vague statutes: Some statutes do not lay down guidelines on the nature of authority and their specific rights and obligations. Example: Delhi's 2009 plastic ban lacked prosecution rules — failed due to poor implementation.
Exclusion of public participation: Industries that profit are always well represented; common people who suffer pollution consequences are not. Public should be stakeholders.
Shortage of funds: Municipalities cannot afford sewage treatment technology. Rivers continue to be polluted despite available technology because municipalities lack funds.
Public opposition: Difficulty in implementing Supreme Court rulings (e.g., mandatory CNG for Delhi public transport; ban on diesel vehicles over 10 years old) due to public opposition from workers and industry.
3
Explain the role of judiciary in environmental protection.
✅ Model Answer
Judiciary plays a vital role as a watchdog that strives to maintain the sanctity and dignity of the Constitution in environmental matters. Public Interest Litigations (PILs) have been a crucial tool:
Taj Mahal Case: Mahesh Chandra Mehta fought 10 years before Supreme Court ordered 230 coal-based industries shut and 300+ to install pollution-control devices. SC also banned cars within 500m of Taj's walls. Mehta won Ramon Magsaysay Award 1997.
Delhi Air Quality: SC ordered all public transport to switch to CNG; banned diesel vehicles over 15 years old; from April 2012 — all new vehicles must meet Bharat Stage-IV (Euro-IV equivalent).
Delhi Factories: In 2000, SC ordered closure of polluting factories in residential areas of Delhi.
Ganga Pollution: SC ordered over 2,000 industries along Ganga to clean up or close; 250 towns to install sewage treatment plants.
National Green Tribunal (2010): Specialised body for expeditious disposal of environmental cases within 6 months. Has authority to provide relief and compensation to pollution victims.
4
List the important government agencies responsible for environment protection in India.
✅ Model Answer
