In a bold move to combat air pollution, the Commission for Air Quality Management (CAQM) has issued binding directives for industries across Delhi and the National Capital Region (NCR). The key mandate sets a maximum particulate matter (PM) emission limit of 50 milligrams per cubic meter, targeting the industrial smoke and dust that’s choking the region’s skies.
This decision comes as authorities recognize industrial emissions as a primary culprit behind elevated PM levels. Not only does this smoke directly pollute the air, but it also contributes to the formation of secondary particulates, worsening the haze that blankets the capital during peak pollution seasons. The CAQM, operational since its inception, has rolled out multiple interventions—from promoting clean fuels to regulating emissions from biomass and fuel-based boilers and kilns.
Backed by comprehensive studies from IIT Kanpur and recommendations from the Central Pollution Control Board’s technical committee, the 50 mg/m³ threshold is deemed both technically feasible and environmentally critical. Implementing this will slash pollution from factories, delivering tangible health benefits to millions living in proximity.
The directive zeroes in on major polluters like food processing units, textile industries with boilers or thermal heaters, and metal sectors with kilns. Exemptions apply only to those already bound by stricter pre-existing norms. Compliance deadlines are staggered: large and medium industries must adhere by August 1, while smaller ones get until October 1.
State governments and pollution control boards have been tasked with rigorous enforcement, public awareness campaigns, and widespread outreach to highlight the urgency. This isn’t just about numbers—it’s a step toward sustainable air quality improvements, reducing respiratory illnesses and enhancing life in one of India’s most polluted urban corridors. As Delhi-NCR breathes easier, this policy signals a commitment to long-term environmental health.
