CAQM invokes GRAP Stage-IV in Delhi-NCR as Delhi's AQI reaches 457
On 17 November 2024 in Delhi, the Commission for Air Quality Management invoked Stage-IV ('Severe+') of the Graded Response Action Plan across the NCR from 8 AM on 18 November.
Summary
On 17 November 2024 in Delhi, the CAQM sub-committee invoked all actions under Stage-IV ('Severe+', Delhi AQI above 450) of the revised Graded Response Action Plan (GRAP) in the entire NCR from 8 AM on 18 November 2024, in addition to Stages I-III. Delhi's daily average AQI was 441 at 4 PM and rose to 457 at 7 PM, as per the CPCB bulletin; low wind speed was cited as the main cause. The 8-point Stage-IV plan stops truck entry into Delhi except for essential goods and LNG/CNG/electric/BS-VI diesel trucks, extends the construction ban to linear public projects such as highways and pipelines, and lets NCR governments move classes VI-IX and XI online and allow 50% office attendance.
