What is GRAP?
The Graded Response Action Plan (GRAP) serves as a structured approach to address air pollution issues in the Delhi-NCR area according to the severity of the situation. The GRAP for Delhi-NCR is divided into four stages of air quality — Stage 1 for “poor” Air Quality Index (AQI) ranging between 201 and 300, Stage 2 for “very poor” AQI of 301-400, Stage 3 for “severe” AQI of 401-450 and Stage 4 for “severe plus” AQI more than 450.
