The Delhi government looking at the worsening air quality has announced yet another ban on vehicles with BS-III petrol and BS-IV diesel engines driven on city roads starting Tuesday.
The announcement was made on Monday when the city’s air quality worsened to the severe category due to unfavorable meteorological conditions, such as calm winds and low temperatures.
As a result, the Commission for Air Quality Management (CAQM) has directed all states in the National Capital Region (NCR) to enforce a more strict anti-pollution measures.
“The ban on BS-III petrol and BS-IV diesel vehicles will kick in from Tuesday since the air quality has deteriorated in the severe category. We are monitoring the situation along with the Environment department. For now, the ban is likely to be in place till Friday. If the air quality improves, the ban could be lifted before Friday,” said a senior Transport department official.
Delhi’s 24-hour average air quality index (AQI) stood at 434 at 4 pm on Monday, worsening from 371 on Sunday.
Earlier, in November the national capital incurred a similar ban when the AQI breached 450. The state government stopped the entry of all commercial vehicles that run on diesel.
An AQI between 401 and 500 is considered ‘severe’, while 301 and 400 is considered ‘very poor’, and 201 and 300 is considered ‘poor’.
