Lahore tops world’s pollution chart as smog hits hazardous levels
Update: This morning, Sunday 1 November, Lahore’s air quality index (AQI) stood at 217 — Very Unhealthy — with PM2.5 the main pollutant, according to weather.com.
Lahore was ranked the world’s most polluted city on Thursday, 29 October, as smog pushed its air quality index (AQI) to 419. The reading, from global monitor IQAir for 10am to 11am, put Lahore ahead of Cairo at 274, while Karachi ranked eighth in the world at 165.
The Punjab government’s own dashboard gave a lower figure, 324, still deep in the hazardous band, which starts at 300. Readings vary because monitors measure at different places and times. The day before, the index stood at 358, with one neighbourhood, Allama Iqbal Town, recording 605. The air eased on Thursday, falling to 183 by 1pm.
It came the same week as a national report on what dirty air is doing to Pakistan. The Pakistan Air Quality Initiative estimates air pollution cuts average life expectancy by about 3.9 years and causes around 128,000 premature deaths a year, costing about 6.5 per cent of GDP. In Lahore, annual average PM2.5 — the fine particles that do the most harm — is above 110 micrograms per cubic metre, over 22 times the World Health Organization’s guideline of five. Sustained exposure at that level could shorten lives in Lahore by up to seven years. Transport is the city’s biggest source of PM2.5 at 35 per cent, followed by industry at 28 per cent and brick kilns at 17 per cent.
Why it matters
Smog is not a one-day problem for Lahore. It returns every winter, when cool, still air traps vehicle exhaust, industrial smoke and crop-burning haze close to the ground. The PAQI report shows the damage is not just a few coughs in November — it is years of life lost, year after year.
What happens next
The Punjab Environment Protection Agency has been stepping up enforcement. From 28 September to 27 October, teams inspected 11,580 brick kilns — demolishing 197 and sealing 163 — and 6,650 industrial sites, sealing 191, with fines of about Rs69 million. Schools in Lahore stopped outdoor activities on Tuesday, but as of Friday, 30 October, the government had not announced any school closures. The disaster management authority has warned smog is expected to intensify from November to mid-December. The federal government has announced a $10 million Clean Air Fund, unveiled by Climate Change Minister Musadik Masood Malik on 28 October.
