Pakistan points to Indian Diwali fireworks for Lahore smog crisis

Pakistan's government has blamed the deteriorating air quality afflicting Lahore on pollution drifting across the border from India following Diwali festivities. The Hindu festival, celebrated over the weekend, saw extensive use of firecrackers across northern India, generating significant quantities of particulate matter that meteorological patterns carried into Pakistani territory.

The timing of the air quality crisis coincides closely with Diwali celebrations, which typically involve widespread firecracker use despite environmental concerns. Northern India experiences regular episodes of severe air pollution during and after the festival season, with major cities frequently recording hazardous air quality index readings.

Transboundary air pollution between India and Pakistan has become an annual concern during winter months, when atmospheric conditions trap pollutants near the ground. The problem affects major population centres on both sides of the border, with Lahore and Delhi regularly experiencing hazardous smog levels during this period.

Both nations have implemented restrictions on firecracker sales and usage in recent years to mitigate pollution during festival seasons. However, enforcement remains inconsistent, and transboundary pollution patterns mean that emissions from one country can significantly impact air quality in neighbouring regions regardless of local mitigation efforts.
