New Delhi, January 20: With a marginal improvement in Delhi’s air quality, the Commission for Air Quality Management in Delhi-NCR and adjoining areas on Tuesday revoked strict measures under Graded Response Action Plan (GRAP) Stage IV, which were in force since January 17, an official said. The CAQM said in a statement, “Delhi’s daily average AQI has shown significant improvement as it recorded 440 on January 18, which improved to 410 on Monday and further improved and recorded 378 on Tuesday as per the daily AQI Bulletin provided by the Central Pollution Control Board (CPCB).”

“Noting this declining trend in the AQI levels of Delhi, the CAQM Sub-Committee on GRAP met today to review the current air quality scenario in the region as well as the forecasts for meteorological conditions and air quality index made available by IMD/ IITM,” it said. GRAP 4 Restrictions Re-Activated in Delhi: GRAP-IV Curbs Reimposed As Delhi-NCR Air Quality Hits ‘Severe’ Levels.

“Further, all actions under Stages III, II and I of the extant schedule of GRAP (November 2025) shall, however, remain in place and be implemented, monitored and reviewed by all agencies concerned in NCR to ensure that the AQI levels do not rise further in the coming days,” said the CAQM. Delhi-NCR School Update: Will Classes Be Held on Monday, January 19 Amid GRAP 4 Curbs?.
