Lahore ranked number one while Karachi ranked fifth among the top five cities with bad air quality in the world.
The second on the list is Croatia’s Zagreb while India’s Delhi is on third, Mumbai fourth, and Pakistan’s Karachi is the fifth city, according to air pollution data released by the United States (US) Air Quality Index.
Lahore suffers from high levels of air pollution, with the city regularly ranking at the top of IQAir AirVisual’s live pollution rankings of the major global cities.
According to environmental experts and an earlier report by the Food and Agriculture Organisation, the cause of smog remains years-long pollution caused mostly by the transport sector and industries, and not just crop burning.
