What's behind this
Diwali 2026 celebrations across Indian cities were marked by severe pollution, excessive noise, fires, deaths and violence, prompting questions about civic responsibility and enforcement when existing rules repeatedly fail. In Delhi, air quality was already critically poor before the festival, with average PM2.5 levels in the week preceding Diwali reaching 236 µg/m³, about twice the 2025 level, according to the Centre for Science and Environment. The findings indicate that firecrackers and stubble burning exacerbate an existing air‑quality crisis.
