India's decision to relax its mandate on flue gas desulphurisation at coal-fired power plants is seen as a shift towards nuanced regulation, aligning with global emission policies tailored to local conditions and climate considerations.
Flue gas desulphurisation systems will now be mandatory only for plants near dense urban zones or critical pollution areas, reducing power generation costs and benefiting customers directly.
Independent assessments showed ambient sulphur dioxide levels well within national standards, justifying the relaxation of the FGD mandate in India. Retrofitting was projected to increase CO2 emissions, leading to the revision.
India's move on FGD regulations is in line with global trends where countries like the US, Europe, and China have shifted towards differentiated enforcement. Critics raise concerns about delaying clean air goals, but governments highlight the focus on pollution hotspots for effective interventions.
