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.

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.
