New Delhi, Oct 20 (PTI) The average PM2.5 pollution in Delhi in the winter season has declined by about 20 per cent as compared to the pre-pandemic period, according to a new report released by the Centre for Science and Environment (CSE) on Thursday.

It also said Diwali this year is being observed early in the season "which means the warmer and windier conditions will help dilute the pollution that is staple of Diwali night celebrations". However, concentrated stubble burning due to prolonged rains (in September end and October) may compound the problem.

The assessment captured seven successive winters and pre-winter trends, starting from January 1, 2015 in Delhi and the National Capital Region (NCR). It is based on real time data available from the 81 operational air quality monitoring stations in the region.
