Owned by HT Media Ltd.Decoded: Why Delhi keeps choking every winter — role of traffic, regional pollution, firecrackers and stubble burning
What's behind this
Delhi‑NCR’s recurring winter smog is driven by several sources rather than a single cause. Vehicle emissions, industrial activity, construction dust, agricultural residue burning and firecrackers all add pollutants, while low wind speeds and temperature inversion trap them near the ground. A revised forecast from the Decision Support System released on Thursday indicates that the transport sector will continue to be the largest contributor over the next few days, with the share from stubble burning remaining relatively low.

Delhi-NCR's recurring winter smog is not caused by a single source. Vehicle emissions, industrial activity, construction dust, agricultural residue burning and firecrackers add to pollution, while low wind speeds and temperature inversion prevent pollutants from dispersing.
