Lahore Suffers from Severe Pollution Spike After Diwali Festivities

As the Diwali festivities illuminated India's skies, the aftermath of celebratory fireworks crossed borders, leading to dire consequences for Punjab, Pakistan. Lahore has now become the second-most polluted city globally, just behind Delhi. The Punjab Environment Protection Department (EPD) reported a significant rise in pollution levels due to both incoming pollutants from Indian regions and local emissions combined with stagnant winds. This pollution surge during Diwali draws attention to the environmental challenges faced by South Asian cities amidst major celebrations.

On Tuesday morning, Lahore's Air Quality Index (AQI) soared to 266, categorizing the air as extremely hazardous. This dangerous spike in harmful particulate matter resulted in the Punjab government initiating urgent measures, such as deploying anti-smog guns and conducting water spraying on critical roads. In light of the deteriorating air quality, authorities have formed specialized smog response teams to address construction site emissions, control traffic flow, and clamp down on industrial pollutants. Residents have been advised to don masks and minimize their time outdoors, as PM2.5 levels hit a staggering 187 µg/m³—about 37 times above the safety thresholds set by the World Health Organization.

City officials have indicated that this drastic drop in air quality is due to both local and international influences. Winds blowing between 4 to 7 km/h have transported pollutants from northern Indian cities like Amritsar, Ludhiana, and Haryana, exacerbating Lahore’s air quality issue. Other cities in Punjab, such as Faisalabad, Gujranwala, Sahiwal, and Multan, are experiencing similar challenges. Authorities, led by Maryam Nawaz, have called attention to the shared nature of cross-border pollution, encouraging residents to curb local emissions as they address the incoming pollution problem. This pollution crisis serves as a potent reminder of how celebrations in one nation can impact neighboring areas.

The Diwali festivities, especially in major Indian cities such as Delhi and Kolkata, saw an extensive use of fireworks, ignoring court-enforced restrictions on “green crackers.” Many areas in Delhi recorded PM2.5 levels soaring past 248 µg/m³, while Kolkata’s levels reached 203 µg/m³. This resultant toxic air reached Pakistan, intensifying an already critical smog situation. In response to the pollution epidemic, Lahore's authorities arrested 83 individuals for unlawful emissions from industrial sites and for waste burning as part of their anti-smog strategy. Residents were urged to remain indoors and utilize air purifiers whenever feasible.

Experts are increasingly highlighting the recurring issue of cross-border pollution during significant festivals in South Asia. Lahore’s dire air situation has raised international alarm, underlining the immediate need for regional collaboration on air quality management. As the Diwali lights dim, a persistent haze hangs over both India and Pakistan, leaving residents to confront the health ramifications of festival-related pollution. This air quality crisis in Lahore highlights the pressing necessity for sustainable practices during celebrations and the collective responsibility of neighboring countries to alleviate environmental ramifications.
