Most polluted cities in Punjab, Pakistan, 2025
1 city in Punjab, Pakistan ranked by their average PM2.5 over the 365 days; 1 above the WHO annual guideline (5.0 µg/m³). The only one: Lahore at 132.3 µg/m³, #1 of 2,624 cities in the world. A city needs measurements on 70% of the days to be ranked.
Punjab has 9 cities ranked over the last 30 days, but only 1 here: most of its monitors have no readings for 2025 in OpenAQ's archive, where ours come from, or too few to rank. Cities missing from this board weren't clean, just not measured.
Ranked by unhealthy days: the share of each city's measured days with a daily mean over 35.4 µg/m³ (US AQI 101+), Unhealthy for Sensitive Groups or worse on the US EPA's scale. Ties go to the higher average.
