CPCB explains why its post-Diwali AQI readings didn’t breach 500

CPCB explains why its post-Diwali AQI readings didn’t breach 500

What's behind this

Delhi‑NCR’s early‑winter air quality has deteriorated, with the average PM2.5 concentration in the week before Diwali reaching a three‑year high, according to a Centre for Science analysis that cites continued vehicular emissions and regional pollution inflow as drivers. IITM modelling found firecrackers to be the city’s top pollutant, peaking on 9 November and falling by 11 November. The city’s AQI has crossed 300, with dust settling on cars, windows and balcony railings. On Diwali night, air‑quality monitors failed to record data, prompting concerns about transparency, infrastructure and government intent.

    Left liberals who remained silent on poor AQI before Diwali turn environmental ‘activists’ on Hindu festival: Exposing their hypocrisy and selective outrage

    The narrative that Diwali alone pushed Delhi into a pollution emergency collapses under the weight of official data for 2026. Diwali this year fell on Sunday, 8 November, because of Adhik Maas. But the air quality had already begun its precipitous decline in the first week of November.
