- The Commission of Air Quality Management (CAQM) has invoked Stage III of the Graded Response Action Plan (GRAP) in Delhi-NCR due to a significant rise in air pollution.
- AQI escalated from 297 (Jan 8) to 357 (Jan 9) owing to calm winds and dense foggy conditions.
- Weather Update:
- Delhi witnessed shallow fog coupled with a persistent cold wave, with the minimum temperature at 5°C and a maximum forecast of 21°C.
- Citizen Advisory:
- Residents are urged to follow the Citizen Charter under GRAP Stage III to mitigate pollution levels.
GRAP Stage III Restrictions
- Ban on Activities:
- Private construction and demolition activities are prohibited.
- Non-essential BS-IV diesel medium goods vehicles are restricted.

Background on AQI Categories
The Air Quality Index (AQI), monitored by the Central Pollution Control Board, categorizes pollution levels as follows:
- 0-50: Good
- 51-100: Satisfactory
- 101-200: Moderate
- 201-300: Poor
- 301-400: Very Poor
- 400+: Severe
The Supreme Court has directed Stage III restrictions for AQI breaching 350 and Stage IV for AQI crossing 400.
Key Context
- The CAQM had relaxed Stage III measures on January 5 as air quality previously showed improvement, but they were reinstated following the recent surge.
- Authorities will continuously monitor AQI trends to determine necessary adjustments to restrictions.
Outlook
The activation of GRAP Stage III underscores the pressing need for measures against deteriorating air quality in Delhi-NCR. Persistent cold weather and calm conditions aggravate pollution levels, highlighting the importance of both citizen compliance and policy enforcement to safeguard public health.
