Current Air Quality Status in Lahore:
- Air Quality Index (AQI): 1039 (US AQI)
- Pollution Level: Hazardous
- Primary Pollutant: PM2.5
Understanding Lahore’s Air Pollution:
Lahore consistently ranks among the most polluted cities globally, highlighted by live pollution data from IQAir. Public awareness surged in 2017, following the first publication of actionable air quality data in Pakistan, thanks to citizen-operated sensors measuring PM2.5 levels. These readings exposed Lahore’s severe pollution, sparking public concern and media attention.
In response, a public interest petition led the Lahore High Court in November 2017 to order the government to enhance smog responses and publish regular pollution data. Consequently, the Punjab Environment Protection Council introduced a Smog Action Plan and an AQI classification, though the criteria have been criticized for underreporting pollution severity.
Government Reporting of Air Quality Data:
While the government has not yet published real-time PM2.5 data, the U.S. Embassy and Consulates began doing so in early 2019. These data, sourced from non-governmental sensors, provide continuous updates on air quality in Pakistan’s major cities.
Seasonal Variation in Pollution:
Lahore’s air quality typically worsens between October and February, when farmers burn crop stubble, exacerbating smog conditions. Temperature inversions during winter trap pollutants, leading to the peak of Lahore’s “smog season,” where it rivals Delhi in pollution levels.
Causes of Air Pollution in Lahore:
Pollution sources in Lahore include vehicular and industrial emissions, brick kiln smoke, crop burning, waste incineration, and construction dust. Deforestation for urban development further aggravates pollution levels. Winter’s temperature inversion traps pollutants, worsening the seasonal smog.
Reducing Lahore’s Air Pollution:
Efforts to improve air quality begin with accessible, real-time data to empower public awareness and protective actions. Reducing emissions from industries and vehicles is crucial, and the government has initiated steps under the Punjab Green Development Program, including monitoring stations across Lahore. Individuals can also contribute by using public transport, carpooling, and opting for eco-friendly fuels.
Health Recommendations:
Avoid outdoor exercise
Keep windows closed
Use masks outdoors
Run an air purifier indoors
