Amid the declining air quality in Delhi and the National Capital Region (NCR), the Commission for Air Quality Management (CAQM) invoked a set of restrictions on November 2 under Stage III of the Graded Response Action Plan (GRAP).

The Sub Committee for the operationalization of the GRAP, after a thorough assessment of the air quality status, meteorological predictions, and air quality index data provided by IMD/IITM, stated that the situation is expected to worsen. It has considered that it is necessary to implement Stage III of GRAP, designated for 'Severe' Air Quality (AQI > 400), with immediate effect as a precautionary step to avoid further deterioration of overall air quality in the NCR.

Restrictive actions mentioned in Stage-I and Stage II of GRAP will also be applicable.

The Central Pollution Control Board (CPCB) has reported a rapid increase in air pollution in Delhi-NCR on November 2. At 5 pm, the average Air Quality Index (AQI) soared to 402, categorizing the air quality in the region as 'Severe' (with an AQI range of 401-450). Earlier in the day, the average AQI for Delhi was 392 at 4 pm, 378 at 3 pm, and 351 in the morning.

Various areas in the city, such as Punjabi Bagh (439), Dwarka Sector-8 (420), Jahangirpuri (403), Rohini (422), Narela (422), Wazirpur (406), Bawana (432), Mundka (439), Anand Vihar (452), and New Moti Bagh (406), reported 'severe' air quality today.

Delhi's air quality has persisted as very poor for the sixth consecutive day. The city's residents woke up to a hazy morning, with temperatures dropping to 16.3 degrees Celsius.

According to SAFAR (System of Air Quality and Weather Forecasting And Research)-India data, Delhi's overall AQI was measured at 336 on November 1, falling into the 'Very Poor' category.

The spike in air pollution was attributed to adverse meteorological conditions, a sudden rise in farm fires, and North-Westerly winds carrying pollutants into Delhi.

The Air Quality Index (AQI) scale classifies air quality into six categories: good (0-50), satisfactory (51-100), moderate (101-200), poor (201-300), very poor (301-400), and severe (401-500). If AQI goes beyond 500, it is labeled as "severe plus."

An 8-point action plan now applicable in the entire NCR includes steps to be implemented/ensured by different agencies and Pollution Control Boards of NCR and DPCC.
