The Brihanmumbai Municipal Corporation (BMC) has directed all 2,224 active construction sites in Mumbai to install air quality monitoring systems, and the mayor said 1,952 sites have complied so far. The move forms part of a campaign to curb rising pollution and to monitor particulate matter and other emissions at source. The civic order requires installation of devices at every active site as part of broader measures to manage urban air quality.

The corporation has issued a detailed 28-point dust-control guideline for construction activities and officials have identified developers who have yet to comply fully with the rules. Several show-cause and stop-work notices have been served on projects found breaching the norms, and orders have been issued to complete installations at the remaining 272 sites at the earliest. Enforcement will be sustained until full compliance is achieved, according to the mayor.

Officials have been instructed to ensure strict implementation of the guidelines across all sites and regular inspections are being held to verify adherence. The mayor emphasised that lapses that occurred in recent years, when oversight was weaker in the absence of elected corporators, are being addressed through daily review meetings by the mayor, the deputy mayor and group leaders. The administration expects coordinated action and stronger oversight to improve the city air quality index over time.

The focus on construction emissions reflects recognition of their role as a major contributor to deteriorating air quality in the city, and the BMC has prioritised dust and emission control within its civic agenda. Technical monitoring combined with punitive action is intended to deter non-compliance and to provide data for targeted interventions. Officials indicated that continued monitoring and enforcement will remain central to the strategy until all sites are compliant.
