The CAQM has directed all implementing agencies to continue enforcing measures under both Stage I and Stage II of Grap across the NCR. The Commission for Air Quality Management (CAQM) on Monday invoked Stage II of the Graded Response Action Plan (Grap) across the National Capital Region (NCR) with immediate effect after Delhi's Air Quality Index (AQI) climbed to 325 at 5 pm, entering the 'very poor' category.
