With Delhi’s air quality deteriorating to abysmal levels, the Supreme Court on Monday prohibited the plying of 15-year-old petrol and 10-year-old diesel vehicles in the national capital and also made it clear that such vehicles would be impounded if found on the roads in Delhi-NCR.
Terming as "very critical" and "horrible" the prevailing pollution situation in Delhi-NCR, the apex court directed that a list of 15-year-old petrol and 10-year-old diesel vehicles be published on the website of the Central Pollution Control Board (CPCB) and transport departments of the NCR area.
On Tuesday, the air quality index (AQI) in the Lodhi Road area was in the ‘poor’ category with PM2.5 at 280 and PM10 at 280.

On Sunday, Delhi recorded its worst air quality of this season as a thick haze engulfed the national capital. The overall AQI was recorded at 381 which falls in the very ‘poor’ category, just points below ‘severe’ pollution level, according to data by the Central Pollution Control Board.

AQI of 0-50 is considered good
AQI of 51-100 is satisfactory
AQI of 101-200 is considered moderate
AQI of 201-300 is graded poor
AQI of 301-400 is very poor

Last week, the Supreme Court had ruled that people in the country can burst firecrackers only from 8 pm to 10 pm only on Diwali permitting the sale and manufacture of low emission “green” firecrackers countrywide.
Environment and health experts welcomed the order, with some describing it as a “spectacular” decision, while others saying it was time the society celebrated festive occasions “more responsibly”.
Authorities attribute the dip in air quality to localised factors such as construction dust, vehicular pollution as well as regional factors such as pollution due stubble burning from neighbouring Punjab and Haryana.
