In Short : Ghaziabad has ranked as India’s most polluted city in FY 2025–26, reflecting persistent air quality challenges. The city recorded the highest particulate matter levels among monitored urban centres, highlighting limited progress in pollution reduction. The findings underline the need for stronger emission controls, dust management, and cleaner transport policies to improve air quality and protect public health.
In Detail : Ghaziabad has emerged as the most polluted city in India during the financial year 2025–26, according to a recent air-quality analysis. The city recorded the highest particulate matter levels among major urban centres, reflecting persistent pollution challenges despite ongoing clean air initiatives and regulatory measures aimed at improving environmental conditions.
The analysis shows that Ghaziabad registered the highest PM10 concentration among cities covered under monitoring programmes. Average PM10 levels were reported at around 215 micrograms per cubic metre, significantly exceeding national standards and placing the city ahead of other heavily polluted urban centres.

Other cities in the National Capital Region also reported elevated pollution levels. Delhi and Noida followed Ghaziabad with similarly high particulate matter concentrations, indicating that air quality challenges remain widespread across the region due to shared emission sources and meteorological conditions.

The report highlights that a majority of monitored cities continued to breach national air quality standards during FY 2025–26. Despite some improvements in select locations, overall compliance remained limited, showing that sustained efforts are required to achieve clean air targets across urban India. ([Down To Earth][1])
Major contributors to pollution in Ghaziabad include vehicular emissions, construction dust, industrial activity, and road dust resuspension. Seasonal factors such as winter inversion and crop residue burning in nearby regions further worsen air quality, leading to prolonged periods of unhealthy pollution levels.
Rapid urbanization and infrastructure development have also added to particulate emissions. Increased construction activities, traffic congestion, and industrial expansion in and around the city continue to place pressure on air quality despite implementation of mitigation measures.
The findings indicate that progress under air quality improvement programmes has been uneven. While some cities achieved reductions in particulate levels compared to baseline years, many urban centres, including Ghaziabad, still reported pollution levels far above recommended limits.
Public health concerns remain significant as high particulate matter exposure is linked to respiratory illnesses, cardiovascular diseases, and reduced life expectancy. Prolonged pollution episodes also impact economic productivity and overall quality of life in densely populated urban areas.
Strengthening pollution control measures such as stricter emission standards, improved public transport, dust suppression, and industrial compliance will be essential. Coordinated action across states in the National Capital Region is also necessary to address transboundary pollution sources.
The ranking of Ghaziabad as the most polluted city in FY 2025–26 underscores the urgency of accelerating clean air initiatives. Enhanced monitoring, policy enforcement, and sustainable urban planning will be critical to reducing pollution levels and improving environmental conditions in the coming years.
