Delhi pollution: What’s allowed and what’s banned in the national capital as GRAP phase IV restrictions kick in after AQI worsens
As Delhi continues to face severe air quality, the Commission for Air Quality Management (CAQM) implemented Phase III and IV restrictions under the Graded Response Action Plan (GRAP) immediately on Wednesday.
This is in line with Supreme Court directives aimed at curbing the rising levels of pollution in the National Capital Region (NCR).
The CAQM Subcommittee on GRAP requests all actions under both Phases III & IV of the revised GRAP throughout the NCR, with immediate effect.

On January 14, the national capital recorded an AQI of 275. However, dense fog, low temperatures, and poor dispersion conditions have resulted in large increases in pollutant concentration levels. The AQI reached 386 on January 15 and continued to rise, reaching 393 at 5 pm and 396 at 6 pm. As of now, the AQI has exceeded 300 marks, which is why it remains in the difficult category. Forecasts from the India Meteorological Department (IMD) and IITM indicated that the AQI may cross the critical 400 mark.
What was the SC order on Delhi pollution?
The Supreme Court, in its December 2024 order, ordered that Stage III restrictions should be applied if the AQI exceeds 350, and Stage IV measures should be applied if the AQI breaches 400. CAQM has implemented these guidelines to prevent further deterioration of air quality. .
Here’s what falls under Tier III and IV restrictions:
– Category III (AQI ‘Severe’): Restrictions include a ban on construction and demolition activities except for essential projects such as railways, metros, and national security infrastructure. Brick burning, stone quarries, and mining activities are stopped.
– Category IV (‘Strong+’ AQI): Strict measures were introduced, such as stopping the entry of trucks into Delhi except those carrying essential goods. Non-BS VI diesel vehicles are banned, and industrial activities dependent on unapproved fuel are stopped.
Counseling of citizens under GRAP
CAQM urged citizens to follow the GRAP constitution, which includes:
1. Minimize outdoor activities and use public transport whenever possible.
2. Avoiding unnecessary use of diesel generators and vehicles.
3. Reducing waste burning and choosing carpooling or work-at-home programs.
All agencies involved in the NCR are directed to strictly enforce, monitor, and review GRAP measures to ensure compliance. A precautionary approach is essential to prevent further increase in air pollution levels.
The GRAP Sub-Committee will closely monitor the air quality situation and forecasts from IMD/IITM. Periodic reviews will guide further actions if needed. Residents and industries in the NCR must face a tougher regulatory environment as authorities try to combat severe air pollution.
