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

Recent Developments (2024–2026)

Forest Conservation Amendment Act 2023 — Governance Shifts and Supreme Court Interim Order

The Van (Sanrakshan Evam Samridhi) Adhiniyam, 2023 (Forest Conservation Amendment Act), which came into force on 1 December 2023, amended the Forest Conservation Act 1980. Key governance changes: (a) restricts the Act's protection to forests recorded in official government records, potentially removing the protection the Supreme Court's 1996 Godavarman judgment extended to all "deemed forests"; (b) exempts a 100-km strip along national borders from forest clearance requirements for strategic infrastructure; (c) permits eco-tourism, safaris, and other specified activities within forest areas without clearance; (d) allows states to establish Eco-Tourism corporations in forested areas.

SC interim order — 4 March 2025: A Supreme Court bench (Justices B.R. Gavai and K. Vinod Chandran) issued a critical interim order on 4 March 2025, directing that "until further orders, no steps will be taken by the Union of India or any of the States, which will lead to reduction of the forest land unless a compensatory land is provided either by the State Government or the Union of India for the purpose of afforestation." This effectively restores a key safeguard pending the constitutional validity hearing. The constitutional validity of the FCA Amendment 2023 is yet to be finally adjudicated by the Supreme Court. MoEFCC issued guidelines in 2024 directing states to complete surveys of "deemed forests" — but petitioners noted many states had not even constituted the required Expert Committees by March 2025.

UPSC angle: Forest Conservation Amendment Act 2023 provisions, deviation from the Godavarman judgment, SC interim order 4 March 2025, and the governance implications are high-priority Mains GS-2/GS-3 content.

Biological Diversity (Amendment) Act 2023 — New ABS Regulations 2025

The Biological Diversity (Amendment) Act 2023, amending the Biological Diversity Act 2002, came into force in 2024. Key changes: (a) exempts AYUSH practitioners from ABS (Access and Benefit Sharing) requirements for codified traditional knowledge use, a response to AYUSH sector lobbying; (b) simplifies access procedures for Indian researchers, academic institutions, and startups; (c) decriminalises procedural violations, replacing jail terms with monetary penalties; (d) adds provisions for intellectual property protection for traditional knowledge databases.

NBA's Biological Diversity (ABS) Regulations, 2025 — notified 29 April 2025: The National Biodiversity Authority notified new Access and Benefit Sharing Regulations on 29 April 2025, operationalising the 2023 Amendment Act's framework. Key features: (a) no benefit-sharing obligation for users with annual turnover up to ₹5 crore; (b) tiered benefit sharing — 0.2% (turnover ₹5–50 crore), 0.4% (₹50–250 crore), 0.6% (above ₹250 crore); (c) digital sequence information (DSI) included in access provisions; (d) NBA allocated ₹6.09 crore to State Biodiversity Boards (SBBs) for implementation capacity. Civil society organisations expressed concern that the 2023 Amendment's AYUSH exemptions and the ABS Regulations' high turnover threshold for waiving benefit-sharing obligations could weaken protection for community-held traditional knowledge and open loopholes for commercial exploitation without adequate benefit sharing.

UPSC angle: BD Amendment Act 2023 — AYUSH exemption, decriminalisation; NBA ABS Regulations 2025 (notified 29 April 2025) — tiered benefit-sharing slabs, DSI inclusion; Nagoya Protocol compliance; traditional knowledge protection are Mains GS-2/GS-3 content.

NGT at 14 Years — Achievements and Challenges 2024

The National Green Tribunal (NGT), marking 14 years of operation in 2024, has handled over 45,000 cases and delivered landmark environmental protection orders. In 2024, the NGT directed remediation of over 2,400 legacy waste dumpsites, issued suo motu orders on wetland encroachment in 17 states, and imposed cumulative penalties of over ₹1,000 crore on industries for water pollution violations.

The World Resource Institute's 2024 assessment ranked India's NGT as one of the world's three most active environmental courts (alongside Brazil's STF and China's Environmental Divisions). However, challenges persist: inadequate technical expertise in specialised benches, pendency of 15,000+ cases, and limited enforcement capacity in states. The Ministry of Law was studying proposals to expand the NGT bench strength and establish circuit courts in all state capitals.

UPSC angle: NGT's 14-year record, case statistics, suo motu powers, comparison with global environmental courts, and institutional challenges are Mains GS-2/GS-3 topics.

Supreme Court: Right to Be Free from Climate Change Adverse Effects (March 2024)

In M.K. Ranjitsinh and Others v. Union of India (21 March 2024), a three-judge bench led by Chief Justice D.Y. Chandrachud delivered a landmark judgment that recognised the "right to be free from the adverse effects of climate change" as a fundamental right under Articles 14 and 21 of the Constitution. The case arose from a petition seeking protection of the critically endangered Great Indian Bustard (GIB) — arguing that overhead power lines in Rajasthan and Gujarat were killing the birds through collision. The Court expanded its inquiry to India's climate obligations, recognising that the right to life (Article 21) and the right to equality (Article 14) together create a constitutional right to a stable climate and freedom from climate change harms.

Significance for environmental law: This is the first time an Indian court has constitutionally grounded a climate right — going further than most courts globally that have only recognised a right to a clean environment. On the GIB issue, the Court balanced conservation against India's renewable energy commitments: it restricted the mandatory undergrounding of power lines to only the GIB "priority areas" (~13,163 sq km) and constituted a seven-member expert committee for the "potential areas," acknowledging that a blanket undergrounding order would impose prohibitive costs on India's solar energy targets. This creates a "constitutional right vs. constitutional duty to decarbonise" tension that is a unique feature of Indian climate law.

UPSC angle: The M.K. Ranjitsinh judgment (21 March 2024) — climate rights as fundamental rights under Articles 14 and 21, GIB conservation vs. RE expansion balance, and the constitutional significance for environmental governance are Mains GS-2/GS-3/GS-4 high-value analytical content.

Green Credit Programme (GCP) — October 2023

The Green Credit Rules, 2023, notified by MoEFCC on 12 October 2023 under the Environment Protection Act, 1986, established India's Green Credit Programme (GCP) — a market-based mechanism distinct from the carbon credit system under the carbon trading scheme.

Key distinction for UPSC: Carbon Credit Trading Scheme (CCTS) under the Energy Conservation (Amendment) Act 2022 targets GHG reduction for obligated entities in hard-to-abate sectors. GCP targets voluntary positive environmental actions (tree planting, water conservation) beyond carbon — not just emitters but any individual, farmer, or company can participate.

UPSC angle: GCP notified October 2023; administrator ICFRE; 8 categories; distinct from carbon credits; voluntary mechanism under EPA 1986. Prelims: the GCP-CCTS distinction is a frequently tested contrast. Mains GS3: voluntary vs. mandatory market mechanisms for environmental protection.

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.
• Root: Latin com- (intensive) + plēre = to fill → complēre = to fulfil → Italian complire; English noun 17th c.
• 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.
• Part of Speech: noun
• Word Family: compliance (n), comply (v), compliant (adj), compliantly (adv), non-compliance (n), compliant (n)
• Usage: Genuine regulatory reform must move governance beyond mere box-ticking compliance towards a culture of voluntary adherence, where citizens and corporations obey the law out of conviction rather than fear of penalty.
• Synonyms: conformity, adherence, obedience, observance, acquiescence, submission
• Antonyms: defiance, non-compliance, disobedience, resistance
• Mnemonic: "Comply = to fill up (Latin complere) the demands placed on you" — when you comply, you completely fill the form/requirement; compliance is the act of filling every box the rule demands.

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.
• Root: Latin ex- = out + fluere = to flow; effluere = to flow out; effluēns = present participle
• Origin: From Latin effluēns, present participle of effluere ("to flow out"), from ex- ("out") + fluere ("to flow"); first used in English in the 1720s.
• Part of Speech: noun; also adjective
• Word Family: effluence (n), efflux (n), effluents (n pl), affluent (adj/n), influent (adj/n)
• Usage: Unchecked discharge of untreated industrial effluent into the Ganga has rendered stretches of the river biologically dead, underscoring why the Namami Gange mission must pair sewage-treatment capacity with strict enforcement of the polluter-pays principle.
• Synonyms: discharge, sewage, wastewater, outflow, runoff, emission
• Antonyms: influent, intake, inflow
• Mnemonic: EF-FLU-ENT = "ex" (out) + "flu" (flow, as in fluid/fluent) — the stuff that FLOWs OUT of a factory pipe. Don't confuse with 'affluent' (rich): the affluent factory dumps effluent.

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.
• Root: Latin ad- = to + battuere = to beat → Old French abatre = to beat down
• 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.

• Part of Speech: noun
• Word Family: abate (v), abated (adj), abating (v pres.p), unabated (adj), abater (n)
• Usage: A credible roadmap for clean air in Indian cities must move beyond episodic restrictions to durable abatement of vehicular and industrial emissions, pairing enforceable standards with fiscal incentives for cleaner technology.
• Synonyms: reduction, mitigation, diminution, lessening, alleviation, curtailment
• Antonyms: intensification, escalation, augmentation, aggravation
• Mnemonic: Think "a-BATE-ment" — to put out bait/abate is to "beat down" (Latin battuere, "to beat") a problem until it shrinks; you beat the nuisance into retreat.

Key Terms

No Development Zone (NDZ)

• Definition: A No Development Zone (NDZ) is a strip of land along India's coastline, measured landward from the High Tide Line (HTL) under the Coastal Regulation Zone (CRZ) Notification, in which construction and new development are largely prohibited to protect fragile coastal ecosystems. The permissible width of the NDZ varies by CRZ category, ranging from 20 metres for certain islands to 200 metres in less-dense rural coasts (CRZ Notification, 2019).
• Context: The NDZ is a regulatory tool first introduced under the original Coastal Regulation Zone Notification of 1991, issued under Section 3 of the Environment (Protection) Act, 1986 by the Ministry of Environment, Forest and Climate Change (MoEF&CC). It buffers the coast against unregulated construction, erosion and storm surge while protecting livelihoods of fishing communities. The Shailesh Nayak Committee (constituted June 2014, reported January 2015) recommended relaxing the NDZ in densely populated rural coasts, which fed into the CRZ Notification, 2018, finally notified as the CRZ Notification, 2019. A key change reduced the NDZ in densely populated rural areas from 200 metres to 50 metres from the HTL.
• UPSC Relevance: This is a foundational GS3 environment concept underpinning UPSC questions on coastal management, the Environment (Protection) Act, 1986 and sustainable development versus economic growth. For Prelims, candidates should know that the NDZ is measured from the High Tide Line and that its width differs across CRZ categories (e.g., 50 m for densely populated CRZ-III A, 200 m for CRZ-III B, 20 m for backwater islands per the 2019 Notification). For Mains, it supports analytical answers on balancing tourism, port development and blue economy with ecological protection of estuaries, mangroves and fishing livelihoods. No verified PYQ asks this exact term, but it is closely linked to the broader CRZ and coastal-ecology theme that recurs in the syllabus.

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 May 2026 — it has not been formally withdrawn, but has also not been adopted. MoEFCC has instead implemented many of its provisions through Office Memorandums.
• 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.
