Firecrackers contributed 71 pc of Delhi's PM2.5 after Diwali: IITM assessment

Firecrackers contributed 71 pc of Delhi's PM2.5 after Diwali: IITM assessment

What's behind this

A Centre for Science and Environment (CSE) analysis of early winter 2026 found that Delhi’s emergency traffic curbs did not reduce congestion or improve air quality, and that Diwali firecrackers caused a sharp pollution spike. The report also looks at the roles of transport, stubble burning and other sources. According to NDTV, the average PM2.5 concentration in the week before Diwali was 236 micrograms per cubic metre, almost double the 120 µg/m3 recorded in 2025, marking the highest pre‑Diwali average in three years.
