Smog and Air Pollution in Pakistan ITS

Pakistan's air quality crisis is persistent, severe, and costly. Fine particulate matter (PM2.5) concentrations routinely exceed the World Health Organization's (WHO) 2021 guideline of 5 µg/m3 annual average; in 2023 Pakistan's national average was 73.7 µg/m3—about 15× the WHO guideline—placing the country among the world's most polluted according to IQ Air's global assessment. These levels drive large health losses, productivity declines, and wide social disruptions, including repeated school closures in Punjab during the winter smog season. The World Bank estimates the economic cost of ambient air pollution in Pakistan at roughly 6.5% of GDP annually, with major contributions from residential solid-fuel use, transport, industry (including brick kilns), agriculture (residue burning), and waste burning. Policy momentum has accelerated (Euro-5 fuel adoption, a National Clean Air Policy, Punjab's Clean Air Plan, kiln modernization), yet implementation gaps, limited monitoring, and the regional “airshed” nature of the problem keep Pakistan highly exposed.
