Over 1,000 construction sites in the city have been issued stop-work notices for violating environmental norms, Minister of State Pankaja Munde said on Tuesday, February 24.
With this, the Maharashtra government and the civic authorities have intensified their crackdown on air pollution in Mumbai.
The environment minister informed the assembly that out of 2,224 active construction sites in the city, 1,952, or nearly 88 per cent, have installed low-cost air quality sensors till January.
According to official data, a total of 1,981 show-cause notices and 1,047 stop-work notices have been issued in the city between October 2025 and January 2026 as part of the ongoing clean air initiative, she said in a written reply on AQI levels.
Munde refuted claims that pollution levels are causing a public health crisis. The minister asserted that the AQI level in Mumbai is satisfactory, 51-100, and moderate, 101-200.
Reports from the Brihanmumbai Municipal Corporation (BMC) and Navi Mumbai Municipal Corporation (NMMC) stated that no adverse health impacts were recorded among vulnerable groups, including children and senior citizens, despite the air quality fluctuating between the 'satisfactory' and 'moderate' categories.
She noted that 678 projects were ordered to halt work on January 16 alone due to a lack of sensor compliance.
Between October 2025 and January 2026, the municipality's 25 ward-level flying squads are actively collecting fines for illegal transportation of waste. They have collected a fine of more than INR 1.21 lakh.
To curb dust pollution, civic authorities deployed 126 water tankers and 25 misting machines, washing over 14408 kilometres of roads.
