10 Indian cities with the least AQI

Clean air in urban areas results from a combination of natural, human-and policy-driven elements that minimize pollutant buildup.

Low-emission sources
Low to minimal industrial activity keeps SO2 and CO low.

Green coverage
High vegetation density traps pollutants. Forest area or tree-lined areas and parks-with Southern cities boost oxygen and sequester CO2.

Policy and monitoring efforts
Strict enforcement of emission norms under the National Clean Air Programme-(NCAP) sustains gains. Continuous Ambient Air Quality Monitoring Stations-(CAAQMS) enable real-time data for interventions. Public transport promotion and electric vehicle adoption curb vehicle exhaust
