Supreme Court Defers FGD Plea to Green Tribunal
8 Sep
Summary
- Supreme Court asked petitioner to approach National Green Tribunal.
- FGD systems reduce sulphur dioxide emissions from coal plants.
- Category 'A' plants are near NCR or million-plus population cities.

On September 8, 2026, the Supreme Court directed a petitioner to approach the National Green Tribunal (NGT) with a plea concerning flue gas desulphurisation (FGD) systems. These systems are essential for mitigating sulphur dioxide emissions from coal-fired thermal power plants. The plea specifically concerns Category 'A' plants, defined as those within a 10 km radius of the National Capital Region or cities with a population exceeding one million.
The petitioner argued that timelines for FGD installation have been repeatedly extended, leading to health issues due to environmental pollution. The Supreme Court noted that the compliance deadline is reportedly set to expire in 2027. The court requested the NGT to prioritize the hearing of the petitioner's request for interim relief and to issue appropriate orders, emphasizing that the merits of the petition have not yet been addressed.
The original petition sought directives for the timely completion and operationalisation of FGD systems in all Category 'A' thermal power plants across the nation. It also requested the formation of a high-power committee to monitor the progress of FGD installations and ensure adherence to emission norms.
