January 6, 2026: In a stringent move to combat worsening air quality, the Brihanmumbai Municipal Corporation (BMC) has ordered the shutdown of 233 construction sites across Mumbai after detecting serious lapses in dust-control and pollution-mitigation norms. The action follows a citywide inspection drive amid a noticeable deterioration in air quality over recent weeks.
Civic officials said show-cause notices were issued to 557 construction projects between December 1 and December 31 for contributing to elevated pollution levels. Subsequent inspections revealed that 233 sites failed to comply with mandatory environmental safeguards, prompting the BMC to halt work at these locations. The crackdown is part of a broader strategy to rein in particulate matter pollution, which typically intensifies during the winter season.
Mumbai currently has over 1,080 air quality monitoring stations operated by the civic body. Areas recording an Air Quality Index (AQI) above 200 were placed under heightened surveillance, with construction activity in these zones subjected to stricter scrutiny. Officials noted that most violations involved the absence of green netting, inadequate water sprinkling to suppress dust, uncovered construction materials, and failure to install air quality monitoring devices at project sites.
Civic authorities pointed out that winter conditions—characterised by lower temperatures and reduced wind movement—trap pollutants closer to the ground, worsening air quality between October and February. “Construction dust is a major contributor during this period. Strict enforcement is necessary to protect public health,” a senior BMC official said.
To strengthen enforcement, the BMC has deployed special teams at the ward level to ensure adherence to pollution-control guidelines. Projects will remain suspended until corrective measures are implemented, while repeat offenders may face fines and further legal action. The civic body has also flagged concerns about inconsistencies in air quality data reported by some private agencies, urging adherence to Central Pollution Control Board (CPCB) protocols.
Reiterating its zero-tolerance stance, the BMC said enforcement will continue without leniency. “Public health cannot be compromised. Any activity adding to pollution will face strict action,” officials said.
