Delhi residents woke up to slightly improved air quality on Monday morning. The national capital recorded an overall air quality index (AQI) of 279, in the “poor” category, against Sunday’s “very poor” AQI of 318. According to the Central Pollution Control Board (CPCB), a layer of haze shrouded the city, slightly blurring silhouettes and hampering visibility.
This comes after the city was under the ‘severe plus’ category for several days last week. An AQI between 0 and 50 is considered good, while 51-100 is satisfactory, 101-200 is moderate, 201-300 is poor, 301-400 is very poor, and 401-500 is severe.
Meanwhile, the Supreme Court is set to review on Monday whether to continue emergency measures under Stage 4 of the Graded Response Action Plan (GRAP) to address Delhi’s air pollution crisis. The decision will determine the future of restrictions aimed at curbing severe air quality levels.
The air quality in the city has shown improvement following Diwali. However, several air monitoring stations have recorded AQI levels between 200 and 300, though a few still remain in the “very poor” category.
Delhi-NCR remains under the Stage 4 pollution curbs of the Graded Response Action Plan. These measures include a ban on truck entry, except for those carrying essential items or using clean fuel like LNG, CNG, BS-VI diesel, or electric. Non-essential light commercial vehicles registered outside Delhi are also prohibited unless they are electric, CNG, or BS-VI diesel. Construction at public projects has been halted entirely.
