The air quality across the Delhi- National Capital Region( NCR) has reached alarmingly high situations, forcing authorities to bring Stage 4 of the Graded Response Action Plan( GRAP), reserved for the worst pollution occurrences.
On the morning of 18 November 2025, Delhi recorded an Air Quality Index( AQI) of 344, placing the megacity in the “ veritably poor ” order, with four monitoring stations registering “ severe ” readings. In response to this deterioration, GRAP Stage 4 restrictions came into effect at 8 a.m. across the region.
Under Stage 4, the rules strain significantly. Heavy vehicle entry from other countries into Delhi has been banned, except for exchanges carrying essential goods or those formerly running on cleaner energies similar as CNG, electric or BS- VI diesel. Construction conditioning are suspended. seminaries( other than for classes 10 and 12) are needed to shift to a mongrel mode.
The pattern of pollutant figure- up is characteristic of the season downtime meteorological conditions combine with high indigenous emigrations, and one major contributor remains the burning of crop residue in conterminous countries like Punjab and Haryana. The Supreme Court of India has taken note of this and directed both state governments to abide rigorously by the recommendations of the Commission for Air Quality Management( CAQM) to check the stubble- burning practice.
The GRAP sets out four stages of raising response Stage I( AQI 201- 300), Stage II( 301- 400), Stage III( 401- 450) and Stage IV( AQI above 450). The current incantation reflects a serious concern that air quality could slip further into the “ severe plus ” range. Although the cited composition mentions the AQI of 344( which itself falls short of> 450), the cast and meteorological outlook putatively urged authorities to takepre-emptive action under Stage 4.
The intention behind these measures is to deaden the worst health impacts of gauze and high situations of particulate matter. Sensitive populations — children, the senior and those with respiratory or cardiovascular ails are specifically advised to stay outdoors as important as possible.
The Supreme Court’s intervention highlights how stubble burning remains a stubborn challenge. It observed that if the CAQM’s recommendations were enforced by Punjab and Haryana, the practice of burning could be “ adequately dived ”. That said, themulti-state, seasonal nature of the problem means results are complex and long- term, involving impulses for alternate crop residue disposal, mechanised outfit for growers, and tighter enforcement.
For the present, the combination of high pollution, restrictive measures and weak winds or inversion layers means a delicate time for the capital region. residers are likely to witness hazy skies, reduced visibility and lesser health threat until conditions ameliorate.
In summary the Delhi- NCR region has entered its most severe air- quality governance for the season. Stage 4 of the GRAP is now in force. Heavy exchanges are barred( with exceptions), construction is broke, seminaries are shifted to mongrel mode( except for crucial elderly- classes), and the courts are obliging girding countries to consolidate sweats against stubble burning. The coming days will be critical — both for rainfall- driven relief and for perpetration of controls.
