Smog Blanket Engulfs Mumbai's BKC; BMC Ramps Up Anti-Pollution Drive
A thick layer of smog blanketed Mumbai's BKC. Discover the BMC's extensive air pollution mitigation plan to tackle the city's air quality.
Residents and commuters in Mumbai woke up to a hazy sight on Saturday morning as a thick layer of smog engulfs Mumbai's Bandra Kurla Complex (BKC). Visuals from the city's premier business hub showed significantly reduced visibility, with a grey veil of pollution hanging over the skyline, sparking concerns about the air quality in the metropolitan area.
The Air Quality Trend: Is Mumbai Improving?
Despite the recent haze in BKC, data provided by the Brihanmumbai Municipal Corporation (BMC) suggests a positive trend in the city's overall air quality over the last few years. According to the civic body, Mumbai has seen an increase in the number of days with 'Good' and 'Satisfactory' Air Quality Index (AQI) ratings.
- 2025: 231 days of Good/Satisfactory AQI (as of October 22)
- 2024: 218 days
- 2023: 216 days
- 2022: 185 days
Furthermore, data from the Union Ministry of Environment, Forest and Climate Change's PRANA portal indicates a significant victory in the fight against particulate matter. The PM10 concentration in Mumbai has reportedly declined by approximately 48 per cent between the 2017-18 and 2025-26 periods.
BMC's War on Dust and Construction Pollution
To combat the causes of smog, the BMC has implemented a rigorous set of measures targeting the construction sector, which is a primary contributor to urban dust. The civic body has introduced a comprehensive 28-point air-pollution mitigation guideline for all construction sites.
Strict Monitoring and Enforcement
The BMC has not left the implementation to chance. A fleet of 76 ward-level mitigation squads has been deployed to conduct surprise inspections. Each squad is mandated to inspect at least two construction sites daily, focusing heavily on identified pollution hotspots.
The consequences for non-compliance are severe. The BMC has the authority to issue show-cause notices, serve stop-work orders, or even seal sites entirely. These actions are backed by photographic and videographic evidence collected during inspections.
Tech-Driven Tracking
In a move toward digitalization, sensor-based air-quality monitors are now mandatory at construction sites. Currently, 3,166 sites have installed these monitors, which feed real-time data into a central dashboard, allowing the BMC to track air quality levels remotely.
Tackling Road Dust and Waste
Road dust is another major culprit in the city's haze. To address this, the BMC is utilizing 29 multipurpose vehicles for deep cleaning and routine sweeping. Additionally, the responsibility has been shared with the private sector; developers and contractors are now required to clean the roads adjacent to their construction projects based on the project's scale.
To prevent debris from polluting the air during transit, the BMC is enforcing strict rules:
- Waste vehicles must remain covered.
- Wheels must be washed before vehicles enter public roads.
- All transportation is tracked via the Mumbai Debris Control and Tracking System (MDCTS).
Beyond Construction: Bakeries and Crematoria
The BMC's strategy extends to other emission sources. Bakeries, which contribute about 3.5 per cent of the city's particulate matter, are being pushed toward cleaner energy. Out of 593 bakeries:
- 209 were already using cleaner fuels.
- 175 have since converted.
- 69 are currently in the process of conversion.
- 87 remain non-compliant, and 8 have shut down.
Additionally, air-pollution control devices are being installed at 10 crematoria, and the city is maintaining strict surveillance over open-burning hotspots.
Winter Preparedness and Public Awareness
With the colder months approaching—a time when smog typically worsens—the BMC has launched the Winter Air Pollution Mitigation and Enforcement Action Plan 2026. This plan focuses on vehicle checks, open burning, and continued construction compliance.
The civic body is also appealing to the public regarding the impact of firecrackers. Awareness campaigns are underway to highlight the noise and air pollution caused by crackers, which remain strictly prohibited on public streets, footpaths, and within silence zones.
