Pakistan’s average life expectancy is reduced by nearly four years because of air pollution, with residents in smog-choked cities such as Lahore losing up to 5.8 years of life if pollution levels were brought into compliance with global safety standards.

A groundbreaking national assessment has for the first time mapped Pakistan’s chronic smog pollution at the city level and concluded that the majority of toxic air pollution is generated locally, not from distant dust storms or cross-border fires. The report has sparked fresh debate over how the country should tackle one of its most persistent public health emergencies.

The Pakistan Air Quality Initiative (PAQI), an independent research collective, this week released Unveiling Pakistan’s Air Pollution and National Landscape Report on Health Risks, Sources and Solutions, which finds that harmful fine particulate matter (PM2.5) from transport, industry, brick kilns, power generation and crop residue burning significantly shortens life expectancy and poses severe health, economic and governance costs.

According to the report, Pakistan’s average life expectancy is reduced by nearly four years because of air pollution, with residents in smog-choked cities such as Lahore losing up to 5.8 years of life if pollution levels were brought into compliance with global safety standards.

Local Sources Dominate

For years, official narratives in Pakistan’s Punjab province have emphasised transboundary smog inflows, particularly from crop burning in neighbouring India’s states, or blamed seasonal dust storms. But the PAQI analysis disputes those claims, showing that city-specific sources – from dense traffic on congested urban roads to unregulated industrial emissions – account for the lion’s share of hazardous air in major urban centres including Lahore, Karachi, Islamabad-Rawalpindi and Peshawar.

“Pakistan’s air quality crises are not a monolithic seasonal phenomenon, but distinct local emergencies shaped by urban design and economic activity,” the report states, emphasising the diversity of pollution profiles across different cities. In Karachi, industry is the dominant driver; in Lahore, transport and brick kilns sit atop the list of polluters; in Peshawar, topographical features trap emissions; and in the twin cities of Islamabad and Rawalpindi, sprawling urban sprawl compounds the problem.

The PAQI findings are based on a combination of satellite aerosol data, chemical transport models and real-time air quality monitoring that the researchers say provide a more robust picture of the country’s emissions landscape than previously available.

Pushback from Environmental Authorities

But the report has drawn sharp criticism from the Punjab Environmental Protection Agency (EPA), which has rejected the study’s conclusions and questioned the credibility of its data and methodology. A spokesman for the EPA said the agency had taken “significant measures” to address smog and that the PAQI lacked access to official monitoring data.

“The government has not closed educational institutions due to smog this year and continuous efforts are being carried out to improve the situation,” the EPA’s representative told the Dawn newspaper, asserting that the agency’s actions have mitigated the impact of seasonal pollution.

Punjab’s authorities have in recent months deployed a series of anti-smog measures, from roadside water sprinkling and anti-smog guns to expanded vehicle emission testing and fines for smoke-emitting vehicles. They also insist that winds and weather have played a role in temporary improvements in air quality at times.

A Pattern of Hazardous Air

Residents in Punjab’s largest cities know the crisis firsthand. Throughout the autumn and early winter this year, Lahore, Faisalabad, Multan and Gujranwala have consistently recorded dangerous Air Quality Index (AQI) readings in the “hazardous” range, with parts of Lahore frequently among the world’s most polluted urban areas.

Medical professionals warn that prolonged exposure to such air can exacerbate respiratory conditions, strain emergency services and contribute to chronic heart and lung disease. Children, the elderly and those with pre-existing health issues are seen as particularly vulnerable to the cumulative impacts of PM2.5, which penetrates deeply into the lungs and bloodstream.

Despite short-term improvements when winds disperse pollutants, Pakistan’s larger “smog season,” which typically lasts from October through February, has become a recurring annual crisis with economic and social costs that reverberate beyond public health into education, productivity and infrastructure planning.

Solutions and Accountability

Experts say the crux of the policy debate now hinges on ownership of the problem. The PAQI report urges policymakers to pivot from seasonal reactionary measures, such as temporary shutdowns and symbolic anti-smog guns, to sustained emissions control, stricter industrial regulation, cleaner transport policies and comprehensive monitoring frameworks.

Environmental advocates have also pointed out that while government initiatives such as vehicle checks and mask mandates play a role, enforcement remains patchy and uneven across districts, and broader structural challenges like unregulated brick kiln operations or lack of green urban planning persist.

In courtrooms, judges have even weighed in. The Lahore High Court recently expressed dissatisfaction with the provincial government’s anti-smog efforts, urging more stringent action against smoke-emitting vehicles and questioning the efficacy of current measures.

With public pressure mounting and health implications growing more visible, both researchers and officials agree that Pakistan’s smog crisis demands urgent attention – whether through consensus on the sources of pollution or robust strategies to curb them ahead of the peak winter months.
