GRADED RESPONSE ACTION PLAN-IV

The Graded Response Action Plan (GRAP) is a rule-based emergency framework for Delhi–NCR that links Air Quality Index (AQI) levels with pre-defined pollution control measures. With air quality currently in the severe to severe+ category, GRAP-IV has been activated to curb emissions and reduce public exposure. While effective in managing short-term pollution spikes, the situation highlights the need for long-term structural solutions to address recurring air quality crises.
