India, May 12 -- The Delhi government has made it mandatory for all construction and demolition (C&D) sites in the national capital to use high-density dust screens, as a step to strengthen dust pollution control measures, officials said on Monday. The Delhi Pollution Control Committee (DPCC) has issued directions that the minimum thickness of green nets to be used at C&D sites has to be 100 GSM (grams per square metre), and all project proponents must comply with the specification with immediate effect, officials added. Delhi Environment Minister Manjinder Singh Sirsa said, "Delhi's fight against air pollution is being pursued with urgency, seriousness and a whole-of-government approach. We are working on all fronts policy changes, scientific interventions, technology-backed monitoring, and stronger enforcement to create a robust protective shield against air pollution in Delhi."

According to the government, earlier norms required construction sites to install tarpaulin covers or green nets around under-construction structures and over stored construction material, but no minimum technical specification had been prescribed for the nets.

Sirsa said, "High-density dust screens are essential for effective dust containment. By prescribing a minimum 100 GSM standard, the government is ensuring that dust mitigation at construction sites is practical, measurable and enforceable." "The Delhi government is committed to ensuring that every anti-pollution norm translates into visible action at the site level," Sirsa added. The government is also working on "Dust Portal 2.0", a centralised digital platform aimed at monitoring and regulating construction and demolition sites across Delhi. Registration of C&D sites on the dust portal has already been made mandatory and officials said the upgraded platform would improve compliance tracking, transparency and enforcement. The DPCC has issued directions for implementation of the order to agencies including the Municipal Corporation of Delhi, New Delhi Municipal Council, Delhi Development Authority, Delhi Metro Rail Corporation, Central Public Works Department and the Public Works Department for immediate compliance.
