Last year, air quality was better in summer: Report
The air in Delhi-NCR was more polluted during the winter season in 2023 as compared to the summer months of the year. This was stated in an analysis report that was released by the Centre for Science and Environment (CSE) on Thursday. The report mentioned that the region witnessed cleaner summer and monsoon seasons and the ingress of smoke from stubble fires in the northern states was much lower in the warmer months. However, pollutants remained trapped in the atmosphere during the winter, leading to a spike in pollution levels. “The summer months of March, April, May and June, 2023, were significantly less polluted as compared to the corresponding period in 2022. However, winter months of January, November and December, 2023, witnessed higher polluted levels than those of 2022,” stated the CSE. It said the region slipped back into the abyss of high pollution levels in the winter of 2023, despite recording a gradual but long-term improvement in the annual PM2.5 concentrations since 2015-17. It added that the forward march towards cleaner air and clearer skies came to a grinding halt in 2023.
