Delhi and NCR have enacted stringent air pollution controls amid severe AQI readings, including activity bans and school schedule changes.

As Delhi and the National Capital Region (NCR) experienced severe air pollution (AQI 401-450) on December 13, 2025, the Commission for Air Quality Management imposed Stage 3 of the Graded Response Action Plan (GRAP). This stage includes immediate bans on construction and demolition activities throughout NCR, prohibitions on BS III petrol and BS IV diesel light motor vehicles in Delhi and select NCR districts, and mandates hybrid mode learning for students up to grade 5. These emergency measures complement previous GRAP stages and respond to data showing multiple monitoring stations with AQI values exceeding 400, signaling hazardous air quality levels threatening public health and safety.
