We do not inherit the Earth from our ancestors; we borrow it from our children.

Introduction
India’s environmental jurisprudence has evolved into a hybrid of robust statutory architecture and proactive judicial interventions.
The interplay between legislation (Water Act 1974, Air Act 1981, Environment Protection Act 1986, Forest Conservation Act 1980, Wildlife Protection Act 1972, etc.) and principles developed by the courts (precautionary principle, polluter-pays, sustainable development, absolute liability) shapes environmental governance today.
This article explains the legal architecture, highlights seminal judicial precedents and case studies, and offers practical recommendations to align Indian law with Sustainable Development Goals (SDGs).
Legislative Framework (Key Acts & Policy Instruments)
India’s principal environmental statutes form layers of protection:
- The Water (Prevention & Control of Pollution) Act, 1974 — regulatory framework for water quality and pollution control boards.
- Air (Prevention & Control of Pollution) Act, 1981 — standards, consent mechanisms, and state CPCBs/PCCs mandates.
- Environment (Protection) Act, 1986 — umbrella law empowering the Centre to set standards and make rules for hazardous substances and environment protection.
- Forest (Conservation) Act, 1980 & Wildlife (Protection) Act, 1972 — restrict diversion of forest land and protect species and habitats respectively.
- National Green Tribunal Act, 2010 — specialist tribunal for speedy environmental adjudication and relief.
Together these statutes deliver the regulatory instruments necessary to pursue SDG-6 (Clean Water), SDG-13 (Climate Action) and SDG-15 (Life on Land).
Fundamental Judicial Doctrines in Indian Environmental Law
Indian courts, particularly the Supreme Court, have progressively read international environmental norms into domestic rights and duties. Core doctrines include:
- Precautionary principle — regulation can and should act to prevent environmental harm even when scientific certainty is incomplete.
- Polluter-pays principle — those who cause pollution should bear remediation and compensation costs.
- Absolute liability / strict liability for hazardous industries — no exceptions for enterprises engaged in hazardous activities; they bear higher standards of accountability.
- Right to a healthy environment as part of Article 21 (right to life) — used as a constitutional basis for environmental protection.
These doctrines often operate jointly to enable effective remedies where statutory enforcement lags. Key judicial decisions have cemented these principles in Indian law.
Case Studies & Judicial Precedents
4.1 Oleum Gas Leak — M.C. Mehta v. Union of India (1986)
The Supreme Court’s orders following an oleum gas leak crystallized the concept of absolute liability for hazardous enterprises and required strict operational safeguards and compensation mechanisms.
4.2 Vellore Citizens’ Welfare Forum v. Union of India (1996)
This landmark case applied the precautionary principle and polluter-pays to industrial pollution from tanneries, directing remediation and long-term measures to prevent further harm — linking environmental protection with human health and sustainable development.
4.3 Indian Council for Enviro-Legal Action v. Union of India (1996)
The Court reinforced polluter-pays and applied strict standards in cases of hazardous waste and contamination, ordering compensation and ecological restoration.
4.4 T. N. Godavarman Thirumulpad v. Union of India (series of orders beginning 1996)
This sprawling litigation defined the ambit of the Forest Conservation Act and established that “forest” must be interpreted broadly. It transformed forest governance and enforced central clearance requirements.
4.5 Taj Trapezium / M.C. Mehta (1996)
In protecting the Taj Mahal, the Court banned highly polluting fuel in the Taj Trapezium Zone, enforcing technology shifts and industrial relocation — balancing cultural heritage with environmental protection.
Role of the National Green Tribunal (NGT)
The NGT, constituted under the 2010 Act, provides specialized, expeditious, and scientific adjudication of environmental disputes and awards compensation for ecological damage.
Its existence has reduced backlog, enabled technical expertise in decision-making, and operationalized many remedial orders. Yet gaps in enforcement and appeals remain.
Challenges in Enforcement & Implementation (and Links to SDGs)
- Regulatory gaps and capacity constraints: State pollution control boards are often under-resourced.
- Implementation gap: Court orders sometimes face delayed or partial compliance.
- Development vs conservation tensions: Forest and infrastructure projects pose recurring legal controversies (SDG-15).
- Climate change governance: India’s mitigation/adaptation duties call for integrating climate law into conventional environmental statutes to meet SDG-13.
Judicial doctrines help fill enforcement gaps, but sustainable implementation requires institutional strengthening, better data, and participatory governance.
Recommendations for Strengthening Green Laws
- Legislative updates: Modernize statutes to explicitly integrate climate targets and nature-positive obligations.
- Strengthen monitoring and transparency: Real-time pollution data, public dashboards and community grievance mechanisms.
- Capacity building for regulators and courts: Technical panels and environmental expert institutions to support decisions.
- Economic instruments: Pollution taxes, restoration bonds, and stronger liability insurance for hazardous industries.
- Community and tribal safeguards: Ensure FPIC (free, prior, informed consent) in projects affecting rights and biodiversity.
Conclusion
Indian environmental law is an evolving hybrid of comprehensive statutes and proactive jurisprudence.
Landmark judgments have embedded global environmental doctrines in domestic law and provided powerful remedial tools. To realize the SDGs and resilient development, India must strengthen enforcement, modernize legislative frameworks to address climate and biodiversity crises, and ensure that legal regimes are backed by institutional capacity and inclusive governance.
