NGT Upholds Environmental Clearance For Great Nicobar Mega Project

NGT Clears ₹72,000 Crore Mega Project in Great Nicobar, Sparking Concerns About Biodiversity and Governance

On 17th February 2026, the National Green Tribunal (NGT) upheld the environmental clearance for the ₹72,000 crore Great Nicobar Island mega-infrastructure project, dismissing mounting challenges related to ecological fragility, tribal rights, and tsunami vulnerability. Anchored near the strategically significant Malacca Strait, India’s southernmost island is set to host an International Container Transshipment Terminal (ICTT), a greenfield dual-use airport, an integrated township, and a 450-MVA hybrid power plant. This ruling is notable not only for its endorsement of large-scale development but also for the sharp departure from the environmental caution the NGT has historically advocated.

Why This Shifts the NGT's Trajectory

The NGT’s decision appears to lean heavily on strategic imperatives, implying an environmental trade-off in favour of India’s geopolitical and economic objectives in the Indo-Pacific. This is a marked departure from the Tribunal’s earlier stance on sensitive biosphere reserves. Consider its 2013 decision in the Western Ghats matter, where it halted highway expansions citing ecological safeguards. Great Nicobar, designated as a UNESCO Biosphere Reserve and home to species like the Leatherback sea turtle and Nicobar megapode, comes with stakes much higher — yet the project has shrugged off stringent opposition. What the ruling achieves is a new precedent: ecological fragility might no longer override national strategy.

The project also signals softer enforcement of established norms. The Island Coastal Regulation Zone Notification, 2019 prohibits construction in CRZ-1A and CRZ-1B areas (ecologically sensitive zones). The official line in this case — that "no part of the project falls in prohibited zones" — relies on a master plan revision yet to be disclosed in full detail. This raises doubts about whether this is compliance or simply creative rezoning. Such decisions could erode the credibility of spatial regulatory frameworks.

The Institutional Machinery and Technical Rationales

The NGT’s ruling is rooted in findings of the High-Powered Committee (HPC), chaired by a former Environment Secretary, tasked with reassessing the project’s clearance after complaints about inadequate baseline data. While the HPC confirmed ecological safeguards — translocation plans for coral, shoreline stabilization, and nesting-area preservation — its reliance on limited site inspections over sustained studies has raised eyebrows. As an example, the Zoological Survey of India’s confidence that no core coral reefs exist is at best provisional, given the archipelago’s unique underwater habitats.

Key institutional players also include the Andaman and Nicobar Islands Integrated Development Corporation (ANIIDC) and the Ministry of Environment, Forest and Climate Change (MoEF). While the ANIIDC is spearheading implementation, its track-record of integrating environmental conditions with large-scale infrastructure is thin. The MoEF has been directed to monitor coral regeneration and turtle nesting sites, but here lies a structural limitation: enforcement in such remote, seismically active terrain will rely heavily on intermittent audits rather than real-time ecological assessment. Capacity constraints are unavoidable.

Ground-Level Data vs. Official Claims

The data provides uncomfortable contrasts. The project claims to divert over 130 square km of forest land, but government estimates suggest up to 700 hectares fall within prohibited coastal zones. Further, while NITI Aayog positions Great Nicobar as a strategic maritime hub, data on seismicity classified the region under Zone V — its highest vulnerability category. The 2004 tsunami destroyed wide stretches of Nicobar’s coastline, an event that raises serious unanswered questions about the infrastructure's long-term safety.

Additionally, the narrative fails to fully address tribal impacts. The island houses indigenous Shompen and Nicobarese communities whose livelihoods revolve around forest and marine reliance. Official documents promise equitable rehabilitation, yet this mirrors what happened during displacement on the West Coast for ports along Gujarat's coastline — ambiguous promises with limited safeguards. Reports from the past decade show tribal dislocation in similar projects often leads to socio-economic marginalization.

The Unasked Questions

Does this clearance push the boundaries of governance? The answer lies in examining the NGT’s capacity to ensure compliance in remote geographies. Great Nicobar is isolated by geography and difficult terrain, making post-sanction monitoring a logistical challenge. The underlying concern should not only be about ecological conditions but structural enforcement gaps in India’s environmental oversight mechanisms.

Then, there’s the troubling issue of ecological resource valuation. Baseline economic assessments often ignore indirect ecosystem benefits. Tropical rainforests and coral reefs are global carbon sinks, yet their economic contributions are discounted entirely when cost-benefit analyses focus narrowly on shipping capacity or GDP boosts. Such calculations are myopic. Moreover, seismic mitigation protocols remain vague — neither NITI Aayog nor ANIIDC has detailed adaptive infrastructure strategies for tsunami zones.

International Contrast: Lessons From South Korea’s Jeju Island

A useful comparative anchor is South Korea's Jeju Global Hub Project in 2018, which attempted similar scaled maritime and aviation infrastructure on an ecologically sensitive island. Unlike the rushed baseline studies in Great Nicobar, Korea conducted a five-year comprehensive Environmental Impact Assessment (EIA) — eventually scaling down shoreline projects after public outcry over disrupted marine biodiversity. Jeju’s model highlights the importance of slowing decision-making to accommodate environmental voices, a cautiousness India overlooks in its ‘strategic environmental clearance’ approach.
