Delhi's Diwali Air Crisis: Worst Pollution in Four Years Amid Missing Data Allegations

Delhi experienced its worst air quality in four years during Diwali, with PM2.5 levels peaking at 675 micrograms per cubic meter. Allegations of missing data arose, but the Environment Minister assured all data was intact. Transport emissions and local festivities contributed to the pollution spike.

Delhi witnessed a severe spike in air pollution during Diwali, recording its worst air quality in four years. The PM2.5 concentration hit a peak of 675 micrograms per cubic meter, a level unseen since 2021.

The Central Pollution Control Board reported a 'very poor' air quality index of 345 at 4 pm Monday, escalating concerns among residents. Climate experts voiced allegations of missing data during peak hours, though Environment Minister Manjinder Singh Sirsa affirmed that all information was intact and the department's digital platforms were operational.

Contributing factors to the pollution included transport emissions and extended festive celebrations, despite the Supreme Court's allowance for green firecrackers within a specific time frame. The return of a pollution-tracking model, the Decision Support System, offered a detailed analysis of pollutant sources, shedding light on stubble burning in neighboring states.
