Delhi’s minimum temperature was recorded at 15.6°C, which was two degrees above normal but the lowest so far this season

To combat the escalating air pollution, the Commission for Air Quality Management (CAQM) has implemented Stage III of the Graded Response Action Plan (GRAP) across Delhi-NCR.

Delhi sees a major spike in air pollution every winter due to several factors, including the burning of farm waste in the adjoining states of Haryana and Punjab.

The GRAP-3 measures include a ban on construction activities and restrictions on the operation of BS-III petrol and BS-IV diesel vehicles in Delhi and the National Capital Region (NCR).

Delhi Airport said that all flight operations are “currently normal” but urged passengers to contact their respective airlines for “updated flight information.”

The GRAP (Graded Response Action Plan) has 4 stages — stage I when AQI ranges between 201 and 300, stage II when AQI is 301-400, stage III when AQI is 401-450 and stage IV when AQI is 450-500.

Delhi's air quality has been categorised as 'very poor' since 30 October, with the season's first 'severe' level recorded on Wednesday.

Delhi faced severe air pollution on Friday, prompting authorities to implement emergency measures. Construction activities were halted, vehicle restrictions imposed, and primary schools shifted online.

The stringent anti-pollution measures under Stage 3 of the Graded Response Action Plan (GRAP) came into force on Friday as Delhi's air quality remains under the severe category.

GRAP stage 3 will come into force at 8am on Friday. The Delhi government announced that classes for primary schools will be shifted to online.

Delhi's air quality dipped to 'severe' with an AQI of 428, prompting the government to enforce stricter pollution control measures under GRAP Stage 2. Environment Minister Gopal Rai attributed the deteriorating air quality to calm winds and lower temperatures,
