Environmental Laws and Governance in India

Key Environmental Laws in India

1.1 Umbrella Legislation

1.2 Pollution Control Laws

1.3 Forest and Wildlife Laws

1.4 Biodiversity Law

Environmental Impact Assessment (EIA)

2.1 EIA Notification 2006

Exam Tip: The EIA process has four stages -- remember "S-S-P-A" (Screening, Scoping, Public Consultation, Appraisal). Category B2 projects are exempt from both EIA study and public consultation -- only a pre-feasibility report is needed. This exemption was a major point of controversy in the Draft EIA 2020, which proposed expanding the B2 category.

2.2 Draft EIA Notification 2020 (Controversy)

Coastal Regulation Zone (CRZ)

3.1 CRZ Notification 2019

Remember: CRZ-IIIA (densely populated rural coast) has an NDZ of only 50 m from HTL, while CRZ-IIIB (sparsely populated rural coast) retains the 200 m NDZ. The population density threshold separating IIIA from IIIB is 2,161 per sq km. UPSC often tests whether the NDZ was reduced uniformly or selectively -- it was selective, applying only to IIIA.

Compensatory Afforestation Fund Act (CAMPA), 2016

Key Environmental Institutions

5.1 Domestic Institutions

5.2 National Green Tribunal (NGT) — Detailed

5.3 NGT Schedule I Laws

5.4 NGT Key Principles Applied

International Environmental Governance

6.1 Key Multilateral Environmental Agreements (MEAs)

Key distinction: Kyoto Protocol vs Paris Agreement -- Kyoto followed a top-down approach with legally binding targets only for developed (Annex I) countries, based on CBDR. Paris follows a bottom-up approach where ALL countries submit NDCs, but targets themselves are not legally binding. Know that the Kigali Amendment (2016) to the Montreal Protocol deals with HFCs (greenhouse gases used in refrigeration), NOT ozone-depleting substances -- it was added to the Montreal Protocol for practical reasons of using existing institutional machinery.

6.2 India's NDC under Paris Agreement

Important for UPSC

Key Themes for Prelims

Vocabulary

Compliance

• Pronunciation: /kəmˈplaɪ.əns/
• Definition: The act of conforming to a rule, standard, regulation, or law, particularly in the context of industries and organisations adhering to environmental or legal requirements.
• Origin: From Italian complire, from Latin complēre ("to fill up, fulfil"), from com- (intensive prefix) + plēre ("to fill"); the English noun emerged in the 17th century.

Effluent

• Pronunciation: /ˈɛf.lu.ənt/
• Definition: Liquid waste or sewage discharged from a factory, industrial plant, or sewage treatment facility into a water body or the environment.
• Origin: From Latin effluēns, present participle of effluere ("to flow out"), from ex- ("out") + fluere ("to flow"); first used in English in the 1720s.

Abatement

• Pronunciation: /əˈbeɪt.mənt/
• Definition: The act of reducing the intensity, amount, or degree of something, particularly the reduction or elimination of pollution, nuisance, or environmental degradation.
• Origin: From Middle English abatement, from Anglo-Norman abatre ("to beat down"), from Old French abatre, ultimately from Vulgar Latin abbatere, from Latin ad ("to") + battuere ("to beat"); attested from the 14th century.

Key Terms

National Green Tribunal

• Pronunciation: /ˈnæʃ.ən.əl ɡɹiːn tɹaɪˈbjuː.nəl/
• Definition: A statutory judicial body established on 18 October 2010 under the National Green Tribunal Act, 2010, for the effective and expeditious disposal of cases relating to environmental protection, conservation of forests, and enforcement of environmental legal rights in India. It has jurisdiction over civil cases arising from seven environmental Acts listed in Schedule I: the Water (Prevention and Control of Pollution) Act 1974, Water Cess Act 1977, Forest (Conservation) Act 1980, Air (Prevention and Control of Pollution) Act 1981, Environment (Protection) Act 1986, Public Liability Insurance Act 1991, and Biological Diversity Act 2002. India was the first developing country to establish a dedicated environmental court.
• Context: "Tribunal" from Latin tribūnal ("raised platform for magistrates"), from tribūnus ("tribune"). The principal bench is located in Delhi, with zonal benches in Bhopal, Pune, Kolkata, and Chennai. The NGT is mandated to dispose of applications within six months. It is governed by principles of natural justice rather than the strict procedures of the Code of Civil Procedure, and is not bound by the Indian Evidence Act, making it easier for conservation groups to present environmental issues. While passing orders, the NGT applies three foundational principles: sustainable development, the precautionary principle, and the polluter pays principle. As of 2025, the NGT is chaired by Justice Prakash Shrivastava (since August 2023).
• UPSC Relevance: GS3 Environment and GS2 Governance. Prelims tests establishment year (2010), the 7 environmental Acts under its jurisdiction, that it follows principles of natural justice (not strict CPC procedure), the 6-month disposal mandate, and that its orders are appealable to the Supreme Court within 90 days. Mains asks about the effectiveness of NGT in environmental governance — landmark orders on Ganga pollution, Delhi air quality, sand mining bans, and solid waste management are current affairs staples. Critically evaluate: whether NGT has been an effective check on environmental violations, challenges of enforcement of its orders, and the tension between expeditious disposal and the complexity of environmental disputes.

Environmental Impact Assessment

• Pronunciation: /ɪnˌvaɪ.ɹənˈmɛn.təl ˈɪm.pækt əˈsɛs.mənt/
• Definition: A systematic process of evaluating the likely environmental consequences of a proposed project or development before a decision is made to proceed, ensuring that environmental concerns are integrated into planning and decision-making through four sequential stages: Screening (determining whether EIA is required and categorising the project), Scoping (Expert Appraisal Committee sets Terms of Reference for the EIA study), Public Consultation (minimum 30 days for public hearings and written responses from stakeholders), and Appraisal (detailed scrutiny of the final EIA report and public consultation outcomes by the Expert Appraisal Committee). Projects are classified into Category A (central appraisal by EAC under MoEFCC) and Category B (state appraisal by SEAC), with Category B further divided into B1 (requires full EIA) and B2 (exempt from both EIA study and public consultation).
• Context: The concept originated in the United States under the National Environmental Policy Act (NEPA), 1969. India adopted EIA through notifications under the Environment (Protection) Act, 1986, with the current regime governed by the EIA Notification, 2006. The Draft EIA Notification 2020, released on 11 April 2020 to replace the 2006 notification, generated massive controversy — 17 lakh public representations were received, and the #ScrapEIA2020 campaign highlighted concerns over reduced public consultation periods (from 30 to 20 days), post-facto environmental clearance for projects that started without approval, and expanded exemptions from public hearings. The draft remains unfinalised as of 2026.
• UPSC Relevance: GS3 Environment. Prelims tests the four stages (remember "S-S-P-A": Screening, Scoping, Public consultation, Appraisal), the governing notification (EIA 2006 under EPA 1986), and the distinction between Category A (central clearance) and Category B projects (state clearance, further split into B1 and B2 — B2 requires no EIA or public hearing). Mains frequently asks about EIA dilution concerns, the Draft EIA 2020 controversies (post-facto clearance, reduced public consultation, expanded exemptions), and whether public participation in EIA is genuinely effective or merely procedural. Connect to Western Ghats ESA debate, mining in forest areas, and the tension between development and environmental protection.
