Lahore tops the world ranking for worst air quality today, according to AirVisual, the real-time air quality map. Karachi comes at Number 4.

The top ten worst ranked cities include two Indian cities - Delhi and Kolkata. The Air Quality Index (AQI) 2022 top 10 cities ranking also includes Baghdad in Iraq and Mongolian capital. It includes three cities from China: Chongqing, Chengdu and Wuhan.

Globally, South Asian cities are far from providing healthy air to their citizens. Bad air quality decreases average life expectancy besides being a source of the spread of diseases.

Since the AQI ranking is real-time, the city ranking may change as the air quality changes.

Every year in early winters, Lahore and adjoining cities are hit by smog. See, above photo.
