Poison in the air

Pakistan's deteriorating air quality has become a public health emergency that demands far more than seasonal interventions and official assurances. The latest findings of the Pakistan Air Quality Initiative (PAQI) show that pollution control measures in Punjab have failed to produce sustained improvements in air quality. Satellite observations detected 16,714 likely crop-residue fires between October 1 and November 9. Lahore recorded an average PM2.5 concentration of 126 micrograms per cubic metre, eight times WHO's daily guideline, with pollution exceeding national standards throughout the 40-day period.

The tendency to attribute Lahore's suffocating atmosphere to pollution originating across the Indian border has also come under scrutiny. Although transboundary pollution remains a legitimate environmental concern, the PAQI assessment found insufficient evidence to link the recent deterioration to Diwali fireworks in India. Instead, the extensive burning of agricultural residue within Pakistani Punjab points towards a substantial domestic problem. Thus, environmental policy cannot be built around convenient explanations that divert attention from local sources of pollution. Crop burning, industrial emissions, vehicular exhaust and construction dust require sustained regulation rather than temporary crackdowns whenever visibility deteriorates.

The human cost is considerably greater than the disruption caused by smog-filled streets and reduced visibility. Fine particulate matter penetrates deep into the lungs and can enter the bloodstream, increasing the risk of respiratory illnesses and cardiovascular disease. According to the University of Chicago's Air Quality Life Index, an average Pakistani could gain 3.3 years of life expectancy if particulate pollution were reduced to meet WHO guidelines. Such estimates should fundamentally change how air pollution is treated in national policymaking. There is also an obvious disconnect between the scale of the problem and the measures employed to address it. Anti-smog guns and water sprinkling may offer limited short-term relief, but they cannot substitute for permanent reductions in emissions. The Punjab Clean Air Programme, supported by $300 million in World Bank financing, already provides a framework for improvements. Yet these investments must translate into measurable improvements rather than another collection of ambitious targets. Farmers require affordable alternatives to residue burning and vehicle fitness regulations need credible enforcement.

Pakistan needs a year-round clean-air strategy backed by enforceable targets and transparent data. The fundamental responsibility of the state is to protect the health of its citizens. Ensuring that the air they breathe does not endanger their lives is among the most basic obligations of governance.
