The Delhi government has decided to impose a temporary ban on using BS-III petrol and BS-IV diesel four-wheelers in the national capital from Tuesday in view of the worsening air quality.
Delhi's air quality worsened to the severe category on Monday owing to unfavourable meteorological conditions -- calm winds and low temperatures -- prompting the Commission for Air Quality Management (CAQM) to direct all NCR states to implement anti-pollution curbs with greater vigour.
"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.
The national capital's 24-hour average air quality index (AQI) stood at 434 at 4 pm on Monday, worsening from 371 on Sunday.
An AQI between 201 and 300 is considered 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.

An air purifier removes airborne contaminants, while a humidifier restores moisture. Understanding their distinct roles, and when to use one, both or none, can help you breathe easier and stay healthier through the season.
The Air Quality Index (AQI) in Delhi and its National Capital Region on Thursday morning remained under the "very poor" category with the Graded Response Action Plan (GRAP) II norms already in place.
Delhi's much-awaited artificial rain experiment, initially postponed in July continues to be on hold, with no green light yet for the trial that was expected to take place after Diwali.
In a time when post-Diwali smog still clouds much of the country, these destinations offer hope - and a reminder that clear skies and fresh air are not luxuries but the new markers of good living.
Both CPCB and IQAir follow different methods of calculating air quality index, resulting in different numbers.

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
