The situation often gets worse because of stubble burning in Delhi's neighbouring states. Air quality in Delhi remained 'very poor' with an overall AQI of 363 whereas more areas of the national capital fell into 'severe' category.

The city was covered in a thick layer of smog as almost all weather monitoring stations fell into the red zone, with more areas moving into the maroon zone of Central Pollution Control Board's color-coded warnings.

A new study reveals how stubble burning in Punjab and Haryana affects Delhi's air quality. Despite a decrease in farm fires, Delhi's AQI remains critically high, highlighting the need for comprehensive interventions and public awareness to tackle air pollution effectively.

Delhi Environment Minister Gopal Rai urged transport ministers of neighboring states to stop diesel buses from entering Delhi due to GRAP II restrictions. He highlighted vehicular emissions from such buses as a major factor in worsening air quality.

The air quality in Delhi has been declining, prompting the authorities to enforce these measures. The second stage of GRAP restrictions came into effect from 8 am.
