The Commission for Air Quality Management (CAQM) on Wednesday revoked Stage-IV restrictions under the Graded Response Action Plan (GRAP) across the National Capital Region (NCR), citing a notable improvement in Delhi’s air quality.
The decision was taken after a review meeting of the Sub-Committee on GRAP, which assessed the current air quality scenario along with forecasts issued by the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM).
According to the CAQM, Delhi’s Air Quality Index (AQI) showed marked improvement due to strong winds and favourable meteorological conditions. On December 24, the AQI was recorded at 271, placing it in the “Poor” category. “The AQI in Delhi has shown significant improvement since last night owing to high wind speeds and favourable meteorological conditions,” the order stated, adding that air quality forecasts still indicate a possible rise in pollution levels in the coming days due to slower wind speeds.
Based on the assessment, the Sub-Committee decided to revoke Stage-IV restrictions, which are imposed when air quality reaches the ‘Severe+’ category. The order clarified that actions under Stage-IV, imposed on December 13, 2025, stand withdrawn with immediate effect.
However, the Commission emphasised that Stages I, II and III of the modified GRAP will continue to remain in force across the NCR. These measures will be closely monitored to ensure air quality does not deteriorate further.
CAQM directed all implementing agencies to maintain strict vigilance and intensify enforcement under Stages I, II and III of GRAP. The aim is to prevent pollution levels from slipping back into the “Severe” category amid changing winter weather conditions.
“All concerned agencies shall ensure strict implementation of the remaining stages of GRAP and maintain constant monitoring,” the order said.
The Commission also appealed to citizens to strictly follow the citizen charter prescribed under GRAP, especially during the winter season when atmospheric conditions are often unfavourable for dispersion of pollutants. While Stage-IV measures have been lifted for now, CAQM said it will continue to closely monitor air quality trends and review the situation periodically based on IMD and IITM forecasts before taking any further decisions.
