Delhi's air quality improved slightly on Tuesday. Wind speed helped clear some pollution. The AQI shifted from 'severe' to 'very poor'. GRAP-IV restrictions remained in place. Schools continued hybrid learning.

Without being “satisfied that there is a consistent downward trend of AQI, we cannot permit the Commission to go down to stage 3 or stage 2,” the Supreme Court bench said on GRAP measures.

The Supreme Court on Monday (November 25, 2024) directed the Centre for Air Quality Management (CAQM) to immediately consider and take a call on relaxing GRAP IV restrictions requiring the discontinuation of physical classes in schools and colleges in Delhi and national capital regions.

Delhi NCR faces severe air pollution as air quality hits 'severe plus.' GRAP Stage 4 enforced, leading to school closures and construction bans.

GRAP 3 air pollution control measures to be imposed in Delhi, Gurugram, Faridabad and Ghaziabad as AQI plummets even further in Delhi NCR.

Supreme Court says that unless satisfied there is consistent decrease in AQI, it can’t order curbs below GRAP-3 or GRAP-2.

Last week, GRAP-IV was imposed in the national capital after the Air Quality Index (AQI) crossed the 450 mark, and the apex court had said that the curbs can't be eased without its approval.
