(MENAFN- Live Mint) In response to worsening air quality in Delhi-NCR, the Commission for Air Quality Management (CAQM) has invoked Stage-IV of the Graded Response Action Plan (GRAP), effective from 08:00 AM on November 18, 2024. The decision follows a significant rise in Delhi's Air Quality Index (AQI), which reached 457 at 7 PM on November 17, indicating 'Severe+' pollution levels.

Rising Air Quality Index triggers emergency action

As per the Central Pollution Control Board (CPCB), Delhi's AQI recorded 441 at 4 PM on November 17, climbing further to 457 by 7 PM. The rapid deterioration in air quality has been attributed to unfavorable meteorological conditions, such as low wind speeds, which have led to a spike in pollutants.

Stage-IV GRAP measures implemented

To address the escalating air pollution , the CAQM has implemented the stringent measures outlined under Stage-IV of the GRAP, which targets 'Severe+' air quality (AQI > 450). These measures are designed to prevent further deterioration of air quality in the region and will complement the actions already in place under Stage-I, Stage-II, and Stage-III .
