Judicial Oversight on Emission Norms: The Role of NGT in Thermal Power Plant Compliance

The Supreme Court’s recent directive to channel grievances regarding Flue Gas Desulphurisation (FGD) systems through the National Green Tribunal (NGT) underscores the judiciary's preference for specialized environmental adjudication in matters of industrial compliance. The core of the dispute lies in the operationalization of FGD technology—a critical mechanism for scrubbing sulphur dioxide emissions—in category 'A' thermal power plants. Concerns have been raised regarding the Ministry of Environment, Forest and Climate Change (MoEFCC) granting exemptions to a significant portion of coal-based power plants, effectively delaying the transition to cleaner emission standards. FGD systems are essential for mitigating the environmental and health impacts of coal combustion, which remains a primary source of air pollution in India. The legal contention highlights a recurring tension between the urgent need for environmental protection and the operational challenges faced by the power sector, including financial constraints and supply chain bottlenecks. By directing the matter to the NGT, the Supreme Court has reaffirmed the tribunal's role as the primary statutory body equipped to handle complex environmental impact assessments and technical compliance issues. The NGT is expected to evaluate whether the exemptions granted by the Ministry align with the 'polluter pays' principle and the broader national commitment to reducing the carbon footprint of the energy sector.
