Delhi Cracks Down: Non-BS6 Vehicles Banned, PUC Mandatory Amid Severe Air Crisis

• Delhi government implements strict measures: ban on non-BS-VI vehicles from outside and non-PUC vehicles within the city.
• Effective from Thursday, announced by Environment Minister Manjinder Singh Sirsa, under GRAP emergency measures.
• BS6 standards, implemented from April 1, 2020, use low-sulfur fuel, DPF, and OBD to reduce harmful emissions like NOx and particulate matter.
• Vehicle emissions contribute up to 40% of NCR's particulate pollution, exacerbated by winter's temperature inversion and stubble burning.
• Over 1.1 million non-BS6 vehicles from Gurugram, Noida, and Ghaziabad will be affected by the entry ban into Delhi.

Why It Matters: Delhi enforces strict BS6 and PUC norms to combat severe air pollution, banning millions of older vehicles.
