New Delhi, May 18 (NationPress) Following a day of strong winds, thunderstorms, and light rains, Delhi's Air Quality Index (AQI) has been reported as 'moderate', leading to the immediate withdrawal of GRAP Stage 1, which had been enforced in the NCR since May 16, according to an official announcement.
The daily AQI Bulletin from the Central Pollution Control Board (CPCB) indicates that today's AQI for Delhi stands at 179. The Ministry of Environment, Forest and Climate Change stated, "In light of the considerable enhancement in Delhi's daily average AQI and in consideration of the meteorological forecasts from IITM/IMD, the Sub-Committee on the Graded Response Action Plan (GRAP) met today to evaluate the air quality situation in the region and make a relevant decision regarding the actions outlined under Stage-I of the current GRAP schedule, effective across the entire National Capital Region (NCR) since May 16, 2025.
After a thorough assessment of the air quality metrics in Delhi-NCR and other factors, the Sub-Committee noted a significant improvement in Delhi's AQI, attributed to strong winds and thunderstorms followed by light rains, which registered an AQI of 179 on May 18 (in the ‘moderate’ category). The IMD/IITM forecasts also suggest that the AQI is likely to remain in the 'moderate' category in the upcoming days.
The statement added, "Consequently, considering this positive trend and the forecasts indicating that Delhi's average air quality will likely stay in the 'Moderate' range in the coming days, the CAQM Sub-Committee has unanimously decided to revoke Stage-I of the current GRAP schedule throughout the NCR, effective immediately."
All relevant agencies of the state governments/GNCTD within the NCR have been urged to maintain these improved AQI levels and prevent any decline into the ‘Poor’ category. They must ensure adherence to all statutory directions, advisories, and regulations issued by the Commission, as well as guidelines from MoEFCC and CPCB, across all contributing sectors.
Moreover, agencies are reminded to heed various actions and timelines specified in the comprehensive policy from the Commission aimed at reducing air pollution in the NCR, particularly focusing on dust mitigation measures.
The Sub-Committee will continue to monitor air quality closely and reassess the situation periodically to make further appropriate decisions based on air quality in Delhi and forecasts provided by IMD/IITM.
