Delhi's Air Hits Severe+ Stage 4 Curbs Triggered

Delhi has entered Stage 4 of the Graded Response Action Plan (Grap) as the Air Quality Index (AQI) surged to 431, breaching the 'Severe+' threshold. This triggered urgent mitigative measures across the National Capital Region (NCR), including restrictions on specific diesel vehicles and a 50% work-from-home directive for government and private offices. Schools up to grade 9 have transitioned to a hybrid learning model with immediate effect.

The Commission for Air Quality Management (CAQM) invoked all actions under Stage 4 following a rapid deterioration in air quality, with AQI increasing by over 80 points in 24 hours. This proactive step comes after significant public and legislative pressure. Noida and Greater Noida also reported severe AQI readings, with shallow fog contributing to vehicular collisions on the Eastern Peripheral Expressway.
