Air quality in Delhi stayed in the 'very poor' category and reached 'severe' at about 20 monitoring stations on Deepavali night as people defied the firecracker ban, with pollution in parts of the city over 50 times the WHO limit.
Curbs in Delhi-NCR follow the Graded Response Action Plan (GRAP), which is enforced by the Commission for Air Quality Management.

How the exam will ask it
ப்ரிலிம்ஸ்
- The Graded Response Action Plan is a set of emergency measures that are invoked in stages as the Air Quality Index worsens in Delhi-NCR.
- The Commission for Air Quality Management, not the Central Pollution Control Board, invokes GRAP stages across the National Capital Region.
- The Air Quality Index groups pollution into six categories, with 'Severe' being the worst band.
மெயின்ஸ்
GS Paper 3 (Environment and Pollution). Recurring post-festival smog shows the gap between a firecracker ban and its enforcement; GRAP and the CAQM provide a graded, region-wide framework. The way forward lies in stricter local enforcement, cleaner alternatives, tackling stubble burning, vehicular and construction dust, and coordinated action among NCR states.

விடையைக் காட்டு
விடை: A — Correct: Commission for Air Quality Management — The Commission for Air Quality Management in the National Capital Region and Adjoining Areas enforces GRAP stages. • Central Pollution Control Board — wrong: The CPCB sets national standards and monitors, but GRAP is invoked by the CAQM. • National Green Tribunal — wrong: The NGT is a judicial body that hears environmental cases and does not enforce GRAP. • Delhi Pollution Control Committee — wrong: The DPCC acts on directions but the plan is invoked by the CAQM for the whole NCR.
