Delhi's air quality deteriorated sharply on Monday, November 2, 2026, forcing the Commission for Air Quality Management (CAQM) to activate Stage 2 of the Graded Response Action Plan (GRAP) across the Delhi-National Capital Region (NCR) immediately. The national capital's Air Quality Index (AQI) registered 325 by 5 PM, firmly placing it in the 'very poor' category.
This swift action follows a significant rise in pollution levels over the preceding three days. Authorities have issued warnings that adverse weather conditions are likely to keep the air quality within the 'very poor' range for several more days.
Rapid Deterioration Prompts Urgent Measures
The CAQM reported a dramatic increase in Delhi's AQI. On October 31, the index stood at 117, classified as 'moderate'. By November 1, it had climbed to 261, and by Monday morning, November 2, it had surpassed the 300 mark, reaching 325 by late afternoon. This rapid decline necessitated the immediate implementation of GRAP Stage 2.
The commission emphasized that additional measures are crucial to mitigate emissions from various sources, including vehicles, diesel generators, commercial establishments, and road dust.
What GRAP Stage 2 Restrictions Mean for Delhi-NCR
Under Stage 2 of GRAP, a series of restrictions are now in effect, targeting both private vehicle use and commercial activities:
- Increased Parking Charges: To encourage a shift towards public transportation, parking fees will be raised significantly.
- Ban on Solid Fuels: The use of coal and firewood in hotels, restaurants, and eateries, including for operating tandoors, is strictly prohibited.
- Diesel Generator Regulations: Tighter controls are being enforced on diesel generator sets to curb emissions from backup power systems.
- Dust Control: Local agencies are directed to intensify mechanical road sweeping and enhance water sprinkling operations, utilizing dust suppressants to prevent airborne particulate matter.
These comprehensive measures are applicable throughout Delhi and the broader NCR region. The CAQM attributed the rapid decline in air quality primarily to unfavorable meteorological conditions that trap pollutants close to the ground.
Forecast Indicates Continued Poor Air Quality
Forecasts from the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM), cited by the CAQM, suggest that air quality is expected to remain in the 'very poor' category over the coming days, underscoring the ongoing challenge faced by the region.
