CAQM invokes Stage-I of GRAP across Delhi-NCR as AQI enters ‘Poor’ category

• CAQM (Commission for Air Quality Management in NCR & Adjoining Areas) is the statutory body that operationalises the Graded Response Action Plan (GRAP) — an emergency, AQI-triggered tiered framework for Delhi-NCR air pollution control.
• Invocation of Stage-I signals entry of Delhi's daily-average AQI into the 'Poor' band (201–300); it activates a 27-point action plan binding on NCR State Govts., GNCTD, ULBs, and central agencies.
• High UPSC salience: intersects environmental governance, cooperative federalism, statutory bodies (Act of 2021 replacing EPCA), and pollution science (PM2.5/PM10, AQI methodology).
