India has 39 of the world's 50 most polluted cities. CPCB NAAQS prescribes limits for 12 pollutants: PM2.5 (60 µg/m³ annual), PM10 (100 µg/m³), SO2, NOx, CO, O3, lead, ammonia, benzene, and benzo(a)pyrene. The NCAP targets 40% PM reduction by 2026 in 131 non-attainment cities.
AirQ Modeller Features
30 India-specific emission factors covering stack emissions (boilers, furnaces, DG sets), fugitive emissions (material handling), vehicular emissions (transport fleet), and construction dust. Source apportionment and benchmarking against both CPCB NAAQS and WHO AQG 2021 (PM2.5 annual 5 µg/m³).
