Context The ₹81,000-crore Great Nicobar infrastructure project has received clearance from the Union Environment Ministry’s Expert Appraisal Committee (EAC), which held that sufficient environmental safeguards have been incorporated while recognising the project’s strategic importance. The decision is significant as it may shape the approach to future strategically important projects located in ecologically sensitive regions. The mega project covers 166 sq km and aims to transform Great Nicobar Island into a major economic and strategic hub. However, it involves diversion of approximately 130 sq km of forest land and the felling of nearly one million trees, raising serious environmental concerns. Overview of the Project Great Nicobar Island spans about 910 sq km and hosts India’s southernmost point, Indira Point. The project envisions converting the island into a strategic gateway in the Indo-Pacific region. Four Core Components Integrated Township The township will cover nearly 149 sq km and include residential zones, commercial areas, tourism infrastructure, logistics facilities and defence establishments. It is designed to anchor long-term economic and strategic activity. Transshipment Port The proposed port at Galathea Bay aims to position India as a maritime logistics hub. It will function as a transshipment facility, transferring cargo from large vessels to smaller feeder ships. The site lies in an ecologically sensitive zone, known for Leatherback turtle nesting and the outflow of the Galathea River. Civil and Military Airport A dual-use international airport is planned east of the port. It will complement the existing INS Baaz Naval Air Station at Campbell Bay. The airport requires acquisition of about 4.2 sq km of land and is expected to affect 379 families. Power Plant A 450 MVA gas and solar-based power plant is proposed to ensure reliable energy supply for the township and associated infrastructure. Land Use and Environmental Footprint The total project area is 166 sq km. Forest diversion accounts for about 130 sq km. Land reclamation includes2.98 sq km for the port1.94 sq km for the airport The project requires around 33.35 million cubic metres of construction material, including cement, rock, sand and steel. Strategic Significance Geopolitical Location Great Nicobar lies close to the , a crucial global maritime chokepoint. Around 94,000 ships transit through it annually, carrying nearly 30 percent of global trade and a substantial share of maritime oil flows. This proximity gives India a strategic vantage point in Indo-Pacific maritime dynamics. Maritime Trade Ambition The Galathea Bay transshipment port is expected to handle 14.2 million TEUs annually. It seeks to compete with regional ports such as Colombo, Hambantota, Port Klang and Singapore. India currently has one operational transshipment port at Vizhinjam in Kerala. Defence Infrastructure The Andaman and Nicobar Command, India’s only tri-services command, has been operational since 2001. The project integrates defence infrastructure into its first phase, strengthening India’s maritime surveillance and operational capabilities in the eastern Indian Ocean. Environmental and Social Concerns Ecological Impact The Nicobar Islands form part of the Sundaland biodiversity hotspot. Almost the entire island falls within the Great Nicobar Biosphere Reserve. The project affects littoral forests, evergreen hill forests and coastal wetlands. The Galathea Bay Wildlife Sanctuary and a megapode sanctuary were denotified. The endemic Nicobar megapode faces habitat disruption. Impact on Leatherback Turtles Galathea Bay is a critical nesting site for Leatherback turtles. While mitigation measures include creation of alternative sanctuaries on neighbouring islands, concerns remain about long-term ecological damage. Indigenous Communities The Shompen tribe, a semi-nomadic hunter-gatherer group with limited external contact, inhabit the interior forests and are highly vulnerable to displacement and disease. The Nicobarese community, many of whom were displaced during the 2004 tsunami, continue to demand restoration of earlier settlements. Projected demographic expansion from about 8,500 residents to 6.5 lakh by 2050 could significantly alter the island’s social and ecological balance. Governance and Implementation The project was initially conceptualised by NITI Aayog and is being implemented by the Andaman and Nicobar Islands Integrated Development Corporation Ltd. A pre-feasibility study was prepared in 2021. Conclusion The Great Nicobar Project represents a strategic attempt to strengthen India’s maritime presence in the Indo-Pacific while enhancing trade and defence infrastructure..However, its scale, ecological footprint and impact on indigenous communities present complex environmental and ethical questions. Balancing strategic imperatives with ecological sustainability and tribal rights will determine whether the project becomes a model of responsible development or a precedent for ecological compromise.
National Green Tribunal (NGT)
Introduction The National Green Tribunal is a specialised judicial body established for the effective and expeditious disposal of cases relating to environmental protection, forest conservation and enforcement of environmental rights in India. It functions as a dedicated environmental court to ensure sustainable development and ecological justice. Establishment and Legal Basis The tribunal was established under the National Green Tribunal Act, 2010. It was created to provide a faster and more specialised mechanism than conventional courts for resolving environmental disputes. Objectives Composition The tribunal consists of: The inclusion of expert members ensures scientific and technical expertise in environmental decision-making. Jurisdiction The NGT has jurisdiction over civil cases relating to substantial environmental questions under key environmental legislations, including: It can provide relief, compensation and restitution for environmental damage. Principles Applied by the NGT The tribunal applies internationally recognised environmental principles, including: Structure The Principal Bench is located in New Delhi. Regional benches are located in Bhopal, Pune, Kolkata and Chennai to ensure wider accessibility. Powers Significance The NGT plays a critical role in strengthening environmental governance in India. It has contributed to improved accountability in cases involving air pollution, river contamination, waste management and forest diversion. By integrating legal and scientific expertise, it bridges the gap between environmental regulation and enforcement. Conclusion The National Green Tribunal represents a significant institutional innovation in India’s environmental jurisprudence.Through specialised adjudication and application of key environmental principles, it enhances access to justice and reinforces the constitutional mandate to protect and improve the environment.

Carbon Capture and Utilisation Technologies – Hard-to-Abate Sectors & India’s Net Zero Plan for UPSC
Carbon Capture, Hard-to-Abate Sectors & EU Bioeconomy Strategy 1) Context India, the world’s third-largest CO₂ emitter, faces rising industrial emissions from cement, steel, power and chemicals. Since these sectors cannot be rapidly decarbonised through renewables alone, Carbon Capture and Utilisation (CCU) is being examined as a transition tool alongside India’s 2070 net-zero target. 2) Carbon Capture & Utilisation (CCU) CCU captures CO₂ from industrial sources (or directly from air) and converts it into fuels, chemicals, construction materials or other products. • CCS: storage underground.• CCU: reuse in economic value chains. 3) What are Hard-to-Abate Sectors? Industries where emissions arise from chemical processes or high-temperature operations, not just fuel use: • Cement (limestone calcination),• Steel (coke in blast furnaces),• Chemicals & fertilisers (fossil feedstock),• Refineries. These emissions are structurally difficult to eliminate without capture technologies. 4) India’s Position • R&D support and draft CCUS roadmap (2030).• Pilot projects in cement and bio-CCU.• Key constraints: high cost, energy intensity, infrastructure and policy support gaps. 5) EU Bioeconomy Strategy The EU Bioeconomy Strategy promotes replacing fossil-based systems with bio-based and circular production. It supports using captured CO₂ as feedstock for fuels, chemicals and materials, linking climate action with industrial transformation under the EU Circular Economy framework.
