Delhi's air quality index (AQI) deteriorated to the "very poor" category, reportedly touching 306 on Monday. Delhi's Environment Minister Gopal Rai attributed the worsening air quality levels to reduced wind speeds brought about by gradually dropping temperatures. Moreover, Rai said on Monday that the second stage of the Graded Response Action Plan (GRAP) has been implemented in the national capital to curb air pollution.
