What Happened

  • The National Green Tribunal (NGT) on February 16, 2026 upheld the environmental clearance (EC) granted in 2022 for the Rs 80,000-crore Great Nicobar Island mega-infrastructure project, declining to interfere with the approval.
  • The NGT cited the project's "strategic" importance and stated there was "no going back," while directing strict adherence to all stipulated environmental conditions.
  • The project, being implemented by the Andaman and Nicobar Islands Integrated Development Corporation (ANIIDCO), involves building an international container transshipment terminal, a dual-use civil and military airport, a township, and a power plant on India's southernmost large island.
  • Critics, including environmental scientists and tribal rights organisations, had challenged the EC before the NGT, citing single-season Environmental Impact Assessment (EIA) data, the felling of approximately one million trees across ~130 sq km of forest, threats to leatherback sea turtles, Nicobar macaques, and the indigenous Shompen tribe.
  • The NGT mandated rigorous conservation plans for leatherback turtles, megapodes, corals, and mangroves, and directed the establishment of independent oversight committees for pollution control, biodiversity protection, and tribal welfare.

National Green Tribunal: Constitution, Powers and Limitations

The National Green Tribunal (NGT) was established by the National Green Tribunal Act, 2010 — a Parliament-enacted statute inspired by Article 21 of the Constitution (right to life, which includes the right to a healthy environment per the Supreme Court's interpretation in Subhash Kumar v. State of Bihar, 1991). The NGT is a specialised quasi-judicial body empowered to hear all civil cases involving "substantial questions relating to environment." It has both original jurisdiction (directly filing applications) and appellate jurisdiction (challenging government orders, including Environmental Clearances). In 2021, the Supreme Court also affirmed that NGT has suo motu powers — it can take up environmental matters on its own, without a petition.

  • NGT established: 2010; headquarters in New Delhi; regional benches in Bhopal, Pune, Kolkata, Chennai.
  • Composition: Chairperson (former Supreme Court judge, appointed by Central Government in consultation with CJI) + at least 10 and up to 20 full-time Judicial Members + Expert Members.
  • Guided by principles of: sustainable development, precautionary principle, and polluter pays principle (Section 20, NGT Act).
  • Not bound by Code of Civil Procedure, 1908 or Indian Evidence Act, 1872; follows natural justice principles.
  • Mandate to dispose of matters within 6 months.
  • Appeals from NGT orders lie before the Supreme Court of India.
  • NGT's jurisdiction does NOT extend to nuclear energy projects (under Atomic Energy Act) or projects cleared by the Supreme Court directly.

Connection to this news: The NGT was the appropriate forum to challenge the Great Nicobar project's Environmental Clearance, given its appellate jurisdiction over ECs. However, the NGT's decision to uphold the EC — despite acknowledging concerns — illustrates the tension between its environmental mandate and the weight given to strategic/national security considerations.

Great Nicobar Island: Ecology and Strategic Significance

Great Nicobar Island is India's southernmost large island (area: ~910 sq km), located approximately 150 km from the Strait of Malacca — one of the world's busiest shipping chokepoints through which ~80% of India's oil imports and trillions of dollars of global trade transit annually. The island is ecologically extraordinary: it is a UNESCO-listed Biosphere Reserve (Man and the Biosphere Programme), contains the Galathea National Park and Campbell Bay National Park (now merged into the Great Nicobar Biosphere Reserve), and harbours tropical evergreen rainforests. It is one of the few nesting sites in India for the critically important Leatherback sea turtle (Dermochelys coriacea) — the world's largest sea turtle, classified as Vulnerable on the IUCN Red List. Galathea Bay, where the container terminal is proposed, hosts approximately two-thirds of all leatherback nesting sites on Great Nicobar.

  • Leatherback sea turtle (Dermochelys coriacea): world's largest turtle, up to 7 feet long, ~900 kg; IUCN status — Vulnerable globally; nests primarily at Galathea Bay on Great Nicobar.
  • Nicobar long-tailed macaque (Macaca fascicularis umbrosa): endemic subspecies, IUCN Vulnerable; found only on the Nicobar Islands.
  • Shompen tribe: approximately 240 individuals; classified as a Particularly Vulnerable Tribal Group (PVTG); nomadic hunter-gatherers; reportedly withdrew consent for the project from the Tribal Council.
  • Great Nicobar Biosphere Reserve: UNESCO designation; part of Man and the Biosphere (MAB) Programme.
  • EIA concerns: Based on single-season (dry season) data, not the mandated multi-season assessment — a major procedural deficiency cited by challengers.
  • Forest diversion: ~130 sq km of tropical rainforest to be cleared; ~1 million trees to be felled.
  • Strategic rationale: proximity to Strait of Malacca and Andaman Sea lanes; dual-use military-civilian airport enhances India's military reach and surveillance in the Indian Ocean Region (IOR).

Connection to this news: The NGT's "no going back" reasoning reflects a broader challenge in Indian environmental law: the precautionary principle (which demands caution in the face of scientific uncertainty) was effectively overridden by strategic and geopolitical considerations — setting a significant precedent for future project clearances.

Environmental Impact Assessment (EIA) and Its Procedural Requirements

The Environment Protection Act, 1986 (EPA) empowers the Central Government to take all measures necessary for environmental protection. Under this Act, the EIA Notification, 2006 (issued under EPA) mandates that certain categories of projects must obtain Prior Environmental Clearance (EC) from the Ministry of Environment, Forest and Climate Change (MoEFCC) or the State Environment Impact Assessment Authority (SEIAA). The EC process involves scoping (identifying impacts to be studied), EIA study (typically requiring baseline data for at least one full year across seasons), public hearing, and review by an Expert Appraisal Committee (EAC) before the EC is granted.

  • Environment Protection Act, 1986: umbrella environmental legislation; empowers the Central Government with sweeping environmental protection powers.
  • EIA Notification, 2006: categorises projects as A (Central clearance, larger/more impactful projects) and B (State clearance) based on size and location.
  • Great Nicobar project category: Category A (Central clearance by MoEFCC's Expert Appraisal Committee).
  • Precautionary principle: a fundamental principle in international environmental law and enshrined in NGT Act — requires preventive action when there is scientific uncertainty about harm.
  • Polluter Pays principle: those who cause pollution must bear the costs of remediation.
  • Compensatory Afforestation: mandated when forest land is diverted; Great Nicobar project's proposed compensatory afforestation in Haryana was criticised as inadequate (tropical forest replaced by scrub land far away).
  • National Wildlife Action Plan 2017-2031: guides wildlife conservation priorities including for marine turtles and endemic species.

Connection to this news: The criticism that the Great Nicobar EIA relied on single-season data strikes at the heart of the EIA process, which explicitly requires multi-season baseline data. The NGT's decision to uphold this EC despite acknowledged procedural concerns raises questions about the robustness of India's environmental clearance process for strategically important projects.
