The Commission for Air Quality Management in NCR and Adjoining Areas (CAQM) announced a revised Graded Response Action Plan (GRAP) for the National Capital Region (NCR) on 21 November 2025. This revision makes the GRAP schedule more stringent to prevent further deterioration of air quality in Delhi-NCR amid worsening pollution levels.
Understanding GRAP and Its Purpose
GRAP is an emergency response mechanism activated based on average Air Quality Index (AQI) levels and meteorological forecasts for Delhi-NCR. It coordinates multiple stakeholders and implementing agencies to take timely and effective actions to combat air pollution. The revised plan is based on scientific data, expert recommendations, and lessons learned from past years to optimize pollution control efforts.
Key Amendments in the Revised GRAP Schedule
The major changes in the GRAP schedule include shifting pollution control measures to earlier stages, effectively making the response more proactive and stringent:
-
Stage I (Poor Air Quality, AQI 201-300): Measures previously under Stage II (such as uninterrupted power supply to avoid diesel generators, better traffic management, public advisories, and augmentation of public transport services) are now implemented at Stage I.
-
Stage II (Very Poor Air Quality, AQI 301-400): Measures previously under Stage III, including staggered office timings for public and municipal bodies in Delhi and key NCR districts, are moved to Stage II.
-
Stage III (Severe Air Quality, AQI 401-450): Measures previously under Stage IV, such as permitting government and private offices to operate at 50% capacity with the rest working from home, are now enforced at Stage III.
Immediate Implementation and Enforcement
CAQM has directed all responsible agencies across the NCR to immediately adopt and enforce the revised GRAP schedule. This updated framework aims to intensify pollution control, especially during the high-risk winter season, to safeguard public health and improve air quality more effectively.
Conclusion
The revised GRAP schedule represents a critical step to combat the persistent air pollution challenges in Delhi-NCR by implementing stricter, earlier interventions. This proactive approach balances scientific assessment with ground realities to prevent further deterioration of the region’s air quality and protect the health of millions of residents.
