As the overall air quality of Delhi worsened to the “severe” category, the Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) on Tuesday (November 11, 2025) morning imposed stricter emergency air pollution control measures in the entire National Capital Region.
“Keeping in view the prevailing trend of air quality, and in an effort to prevent further deterioration of air quality in the region, the Sub-Committee (of the CAQM) today has taken the call to invoke all actions as envisaged under Stage-III of extant GRAP – ‘Severe’ Air Quality, with immediate effect, in the entire NCR. This is in addition to the actions under Stages I & II of extant GRAP already in-force in NCR,” the CAQM said in a statement.
The decision was taken after Delhi’s average Air Quality Index (AQI) rose sharply from 362 on Monday to 425 on Tuesday morning due to calm winds, a stable atmosphere and unfavourable weather conditions that allowed pollutants to accumulate close to the surface, the Commission for Air Quality Management (CAQM) said.
The implementation of Stage III curbs, which include a ban on non-essential construction work and closure of stone crushers and mining activities, is in addition to the actions already enforced under Stages I and II of GRAP.
Classes up to Class 5 are required to shift to hybrid mode under Stage 3. Parents and students have the option to choose online education wherever available.
Under Stage 3, the use of BS-III petrol and BS-IV diesel cars (4-wheelers) is restricted in Delhi and nearby NCR districts. Persons with disabilities are exempt.
During winters, the Delhi-NCR region enforces restrictions under GRAP, which categorises air quality into four stages – Stage I (Poor, AQI 201-300), Stage II (Very Poor, AQI 301-400), Stage III (Severe, AQI 401-450), and Stage IV (Severe Plus, AQI above 450).
