On Friday morning at 8 am, Delhi’s Air Quality Index (AQI) rose to 186, up from 161 the previous day, as reported by the Central Pollution Control Board (CPCB). Despite the increase, air quality remained in the “moderate” category for the third consecutive day. Due to the improvement, the Centre’s air quality panel for Delhi-NCR lifted the restrictions under Stages III and IV of the Graded Response Action Plan (GRAP).
AQI Across the National Capital
With air quality improving from “poor” to “moderate,” this trend is expected to continue for the next two to three days. Most areas in Delhi reported moderate air quality this morning. For instance, according to CPCB data at 8 am, ITO had an AQI of 182, Chandni Chowk 122, Major Dhyan Chand 169, Patparganj 194, and Mandir Marg 162, among others.
While some areas in Delhi are still experiencing “poor” air quality, others are awaiting improvement to the “moderate” category. For example, according to CPCB’s 8 am readings, Anand Vihar recorded an AQI of 245, Vivek Vihar 204, Sonia Vihar 205, and Nehru Nagar 235.
Restrictive Measures Eased from GRAP-IV to GRAP-II
Following Delhi’s first “moderate” air quality report this winter on Wednesday, the Centre’s air quality panel for Delhi-NCR lifted the restrictive pollution control measures under Stages III and IV of the Graded Response Action Plan (GRAP) on Thursday, as per an official order.
The restrictions have now been eased to Stage II of GRAP, which implements less stringent measures. These include a ban on the use of coal and firewood in industries, commercial establishments, and eateries.
Earlier in the day, the Supreme Court permitted the Commission for Air Quality Management (CAQM) to reduce the restrictions under GRAP-IV to Stage 2, citing improvements in the region’s air quality. On Thursday, Delhi residents enjoyed cleaner air for the second consecutive day, with the AQI recorded in the “moderate” category at 165.
The Supreme Court noted that AQI levels in the National Capital Region (NCR) had not exceeded 300 in the past four days. It directed the CAQM to reinstate Stage III restrictions if the AQI surpasses 350, and Stage IV if it exceeds 400.
Stages III and IV of GRAP impose stricter measures, including a ban on the entry of trucks carrying non-essential goods unless they run on CNG, LNG, or BS-VI diesel. Diesel-powered medium and heavy goods vehicles (BS-IV or lower) are prohibited, except for essential services. Non-essential light commercial vehicles from outside Delhi are also restricted. Additionally, all construction and demolition activities, including public infrastructure projects such as highways, flyovers, and pipelines, are suspended under these stages.
