Lahore recorded a 15 per cent net improvement across six major air pollutants during the first year of the Punjab government’s real-time air quality monitoring programme, while the city’s peak Air Quality Index declined by 28 per cent in October 2026 compared with the corresponding period last year, according to a report released by the Environment Protection and Climate Change Department, known as EPCCD. The findings suggest measurable progress in the city’s air quality, even as smog remains a seasonal challenge.
The improvement reflected reductions across six major pollutants rather than a single parameter, particularly fine particulate matter, known as PM2.5. That breadth is important. An improvement driven by only one pollutant could be misleading, or could reflect a temporary factor affecting that pollutant alone. A net improvement across six pollutants, with a particular emphasis on PM2.5, points to a more general improvement in air quality. PM2.5 is especially significant for health, because fine particles can penetrate deep into the lungs and are associated with respiratory and cardiovascular problems.
Lahore recorded no days in the hazardous Air Quality Index category, above 300, during October 2026, against four such days in October 2025. The hazardous category represents the worst level of air quality, at which health risks are greatest for the whole population. The absence of any such days in October 2026, compared with four in the previous October, is therefore a notable change. It suggests that the worst episodes of air pollution, at least in October, were avoided this year.
Findings were based on the first full year of real-time monitoring and publicly available ground-based measurements. Real-time monitoring provides continuous data on air quality, rather than periodic samples, and ground-based measurements offer a direct record of conditions at monitoring stations in the city. The combination of a full year of data and publicly available measurements gives the report a solid basis, allowing comparisons to be made over a complete annual cycle rather than over a short or selective period.
According to Pakistan Meteorological Department statistics, Lahore received 50 per cent less rainfall in October 2026 than in October 2025, indicating the improvement came despite drier conditions. Rainfall can help to clear pollutants from the air, so a year with less rainfall might be expected to have worse air quality, all else being equal. The fact that air quality improved despite receiving half the rainfall of the previous October strengthens the case that the improvement reflects factors other than favourable weather.
The report’s findings also have implications for public health and for policy. A 15 per cent improvement across six pollutants and a 28 per cent decline in peak AQI in October, if sustained, would represent a meaningful reduction in exposure to harmful air pollution for Lahore’s residents. The fact that the improvement came despite drier conditions and only a small change in mixing layer height suggests that policy measures, including the anti-smog strategy, may be having an effect, although the report itself does not attribute the improvement to any single measure.
For residents, the most tangible indicator is the absence of hazardous days in October 2026. Four hazardous days in October 2025 would have meant days on which outdoor activity carried serious health risks for everyone. Their absence this October is a concrete improvement in daily life, even if smog remains a concern on other days.
The first full year of real-time monitoring provides a baseline against which future years can be measured. As monitoring continues, further annual comparisons will show whether the improvement recorded in this first year is the start of a sustained trend or a one-year variation. For now, the EPCCD report presents a positive picture for Lahore’s air quality in October 2026, set against drier weather and broadly similar atmospheric conditions.
