Mumbai’s air quality has been a topic of intense discussion recently, with the city grappling with rising pollution levels. While some experts voice concerns about the worsening air quality, an official report claims otherwise. According to the report, Mumbai’s air quality has actually improved over the past five years. Despite this, many remain skeptical, questioning the accuracy of these findings. The Waatavaran Foundation, an NGO, reports a significant reduction in pollution, with the number of `good` and `satisfactory` air quality days rising by 24 percentage points, from 36% in winter 2020-21 to 60% in 2024-25. The number of ‘good’ air quality days has doubled from 9% to 18%, while ‘poor’ and ‘very poor’ days have also dropped, with poor air quality days falling from 18% to 7%, and very poor days from 14% to just 2%.
