An analysis of the Air Quality Index (AQI) across major Indian cities from 2015 to November 2025 has revealed that Bengaluru has the cleanest air among metros.
However, the findings said that though Bengaluru shows the best air quality, it is still not “safe.” According to Climate Trends AQI data across major Indian cities from 2015 to November 2025, none of the top urban centres in India can be considered “safe” in terms of air quality.
Climate Trends is a research-based consulting and capacity building initiative.
“AQI remains between 65 and 90 most years, although comparatively cleaner, these values still exceed the ‘Good’ category, but rapid urbanisation and vehicle growth prevent the city from falling into safe range,” states the key finding for Bengaluru.
