While it is clear that the air has been considerably cleaner, a report published by the Brihanmumbai Municipal Corporation (BMC) has stated this with relevant reasons. The BMC admitted that it is the result of the closure of industrial and construction activity.

The BMC published a report of pollution levels at 16 spots in the city between January and May 2020. The level of PM 10 (particulate matter of 10 micrometres or less in diameter), PM 2.5 (particulate matter of 2.5 micrometres or less in diameter), nitrogen dioxides, ozone and carbon monoxide were reported every day.
