The Delhi Pollution Control Committee (DPCC) has introduced a new regulation requiring all construction sites in Delhi to use green nets with a minimum thickness of 100 grams per square meter (100 GSM). This decision follows assessments indicating that many existing nets were inadequate, allowing dust particles to escape and worsen air quality. Dust pollution is a critical issue in Delhi, contributing significantly to PM10 and PM2.5 levels, especially during winter and summer months. The new rule aims to ensure that dust barriers are effective rather than merely symbolic. The DPCC has directed major agencies, including the Municipal Corporation of Delhi and the Delhi Development Authority, to implement this standard immediately, with enforcement measures in place for non-compliance. Experts have welcomed the move but emphasize the importance of proper installation of the nets to maximize their effectiveness. Additionally, the Delhi government is developing Dust Portal 2.0, a centralized platform for monitoring construction sites as part of its broader anti-pollution strategy.
