Lahore's air quality is hazardous to health
Lahore, the capital of Pakistan's most populated province, Punjab, has been ranked as the world's most polluted city. The city's air quality has been described as "hazardous" and a threat to the health of its citizens.
Lahore's air quality index (AQI) score has reached alarmingly high levels, often several times higher than the World Health Organization's (WHO) recommended values. For example, in 2025, Lahore's AQI reached 271, falling into the “very unhealthy" category. The PM2.5 concentration was 39.2 times the WHO's annual PM2.5 guideline value.
The poor air quality in Lahore is caused by a combination of several factors, including vehicle emissions, industrial pollution, power plants, the burning of waste materials, and coal burned in brick kilns. The city has lost a significant proportion of its tree cover due to aggressive construction projects, and the lack of vehicular inspections and poor fuel quality have further exacerbated the problem. The wind patterns during the stubble-burning season also contribute to the pollution, as they bring in smog and pollution from neighbouring regions.
The hazardous air quality in Lahore has severe consequences for the health of its residents. During periods of high pollution, authorities have been forced to close schools, offices, malls, and parks to reduce human exposure and traffic emissions. The smog has also disrupted flights and caused major road closures. In November 2024, the smog in Lahore reached an AQI of 1067, sickening tens of thousands of people.
To tackle the air pollution crisis, the Punjab government has imposed a provincial embargo on Euro 2 fuel supplies and established a “smog war room" to monitor the situation. The government has also set up anti-smog squads and taken measures to reduce pollution from brick kilns. However, the effectiveness of these measures has been limited due to a lack of enforcement capacity and contradictory positions adopted by decision-makers.

Vehicular emissions are a major contributor to Lahore's pollution
Lahore, Pakistan's second-largest city, has been dubbed the world's most polluted city. The city has a population of about 13 million and is a hub for commerce, banking, and industry. Its air quality index (AQI) score has reached levels as high as 1165, which is alarmingly over 120 times the recommended levels by the World Health Organization (WHO).
One of the primary contributors to Lahore's poor air quality is vehicular emissions. The city has witnessed a surge in car sales, with an estimated 2 million small vehicles, 4.5 million motorbikes, and about half a million buses and trucks on its roads. While buses emit more pollutants per vehicle, the sheer number of smaller vehicles and motorbikes means they collectively contribute a much higher volume of pollutants. The lack of proper vehicular inspections and the use of poor-quality fuel have exacerbated the problem, with many cars spewing toxic emissions due to adulterated fuel and a lack of maintenance.
To address this issue, the Punjab government has implemented several measures. They have introduced vehicle emission testing points across Lahore, aiming to monitor and control emissions from all types of vehicles. These tests assess levels of pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides, which are major contributors to smog and respiratory issues in urban areas. The government is urging all vehicle owners to get their vehicles tested and certified, with fines for those who do not comply. This initiative is a significant step towards reducing vehicular pollution and improving air quality, not just in Lahore but eventually across the entire Punjab region.
In addition to vehicular emissions, other factors contributing to Lahore's pollution include industrial pollution, fossil fuel-fired power plants, waste burning, and coal-fired brick kilns. The city's proximity to the India-Pakistan border also plays a role, with seasonal crop burning and fluctuating wind patterns impacting air quality. To combat these issues, the government has set up a "`smog war room'" and is working with neighbouring India to address the shared issue of toxic air.
Lahore's pollution problem is a complex issue with various contributing factors. Vehicular emissions are a significant part of this problem, and the government's efforts to regulate and reduce these emissions are a crucial step towards improving the city's air quality and the health of its citizens.

Industrial pollution and brick kilns add to Lahore's poor air quality
Lahore, Pakistan's second-largest city, has been ranked as the world's most polluted city. The city's poor air quality is attributed to various factors, including industrial pollution and brick kilns, which significantly contribute to the high levels of air pollution.
Industrial pollution is a significant contributor to Lahore's poor air quality. The city is a hub for commerce, banking, and industry, with many factories and industrial operations. The fuel and energy sector, including refineries, are among the primary polluters in the country. The low quality of vehicle fuel and the lack of vehicular inspections also play a role in the city's air pollution problem. The burning of fossil fuels, waste materials, and coal in power plants and other industrial processes releases toxic emissions into the atmosphere.
Brick kilns are another major source of air pollution in Lahore. Brick kilns release large quantities of organic pollutants and carbon dioxide emissions, adding to the city's poor air quality. The burning of coal and other fuels, such as tyres, wood, waste oil, and cow dung, in brick kilns contributes to the high levels of particulate matter and black carbon in the air. The social survey's findings reveal a direct association between particulate matter and respiratory diseases like asthma, affecting all age groups in the selected sampling areas.
In recent years, the provincial government and environmental agencies have taken steps to address Lahore's air pollution crisis. The Environmental Protection Department introduced an 11-point policy to control emissions from vehicles and factories, and the city administration has cracked down on smoke-emitting factories, brick kilns, and vehicles, imposing fines to reduce air pollution. However, data still indicates that air pollution in Lahore remains significantly higher than the World Health Organization's safe limits, and the city continues to face the challenge of improving its air quality to ensure the health and well-being of its citizens.

Lahore's pollution is caused by a combination of meteorological and anthropogenic factors
Lahore, the capital of Pakistan's most populous province, Punjab, has been ranked as the world's most polluted city. The city's air quality index (AQI) score has been recorded at levels that are tens of times higher than the World Health Organization's (WHO) recommended values.
Anthropogenic factors also play a significant role in Lahore's pollution. Vehicular emissions, due to a lack of inspections and poor-quality fuel, are a major concern. The city has seen a rise in car sales, with many vehicles emitting toxic pollutants due to fuel adulteration. Additionally, industrial pollution, fossil fuel-fired power plants, the burning of waste materials, and coal-fired brick kilns contribute to the problem.
The loss of tree cover due to aggressive infrastructure development has further exacerbated the situation. Over the past 15 years, Lahore has lost a significant proportion of its trees to make way for highways, underpasses, and overpasses. This has resulted in a decrease in the city's ability to absorb pollutants naturally.
The government has implemented various measures to combat Lahore's pollution, including the imposition of fines on polluters, the formation of anti-smog squads, and the establishment of a "`smog war room'" to monitor and address the issue. However, the enforcement of these measures has been inconsistent, and the problem persists.

Lahore's government is tackling pollution by setting up a smog war room
Lahore, the capital of Pakistan's Punjab province, has been ranked as the world's most polluted city. The city's air quality index (AQI) score reached a staggering 1165, according to Swiss group IQAir, which is more than 120 times the recommended levels by the World Health Organization (WHO). The fine particulate count has also been recorded at 40 times the WHO's guideline values.
The primary causes of Lahore's poor air quality are vehicular emissions, industrial pollution, power plants, the burning of waste, and coal usage in brick kilns. The city's proximity to the Indian border also plays a role, with wind patterns bringing in pollution from India during the stubble-burning season.
To tackle this severe pollution crisis, the Lahore government has taken several measures. One key initiative is the establishment of a "smog war room" to monitor and combat pollution. The smog war room committee, comprising staff from eight departments, conducts twice-daily sessions to review weather and air quality forecasts, monitor the performance of field officers, and coordinate efforts to reduce pollution. They also issue daily advisories to stakeholders and the public.
In addition to the smog war room, the government has imposed a provincial embargo on Euro 2 fuel supplies to improve fuel quality and reduce vehicular emissions. Anti-smog squads have been formed, and punitive measures target farmers who burn stubble and illegal brick kilns. On severely polluted days, offices and schools are closed to reduce human exposure and traffic emissions.
While Lahore continues to face significant pollution challenges, the government's efforts, particularly the establishment of the smog war room, demonstrate a commitment to addressing the issue and improving air quality for the city's residents.
