Pollution response action plan revised for Delhi ahead of winter season

With winter approaching and the possibility of Delhi's air quality plunging looms large as usual, efforts have been launched in the capital to enable effective response to air pollution and related situations.

The Commission for Air Quality Management (CAQM) has rolled out its revised Graded Response Action Plan (GRAP) for this year as a strategic measure to tackle air pollution in the National Capital Region (NCR), officials said on Wednesday.

The implementation, formalised through a notification, segments actions into four responsive stages based on the Air Quality Index (AQI)- Stage I 'Poor' (AQI 201-300), Stage II 'Very Poor' (AQI 301-400), Stage III 'Severe' (AQI 401-450), and Stage IV 'Severe+' (AQI >450).
