On 18 November 2024 , the Supreme Court announced its consideration of issuing an order to keep the Graded Response Action Plan (GRAP) IV in effect in Delhi, even if the Air Quality Index (AQI) improves and drops below 300. This move aims to address the worsening air quality levels in the city, as discussed in the case In Re: Commission for Air Quality Management .
GRAP IV is typically enforced when the AQI surpasses 450. It includes strict measures such as a total ban on construction activities, the closure of schools, and the implementation of the odd-even vehicle rationing scheme.
“We want to make it absolutely clear that you cannot step down from Stage 4 without our approval, even if the AQI falls below 300. This is the order we intend to issue,” stated the Bench comprising Justice AS Oka and Justice AG Masih.
The Bench was considering a petition requesting the implementation of measures to address the ‘severe’ Air Quality Index.
GRAP IV has been implemented in the national capital by the Commission for Air Quality Management (CAQM) in response to the deteriorating AQI. Under GRAP IV, the entry of trucks into Delhi is prohibited, except for those transporting essential goods or providing essential services.
Under GRAP IV, light commercial vehicles registered outside Delhi except electric vehicles, CNG vehicles, or those running on BS-VI diesel are barred from entering the city unless they are transporting essential goods or providing essential services.
