Delhi’s air quality improves for the January–May period, with the national capital posting its lowest average Air Quality Index (AQI) in eight years, aside from the Covid-impacted year of 2020. Multiple outlets report that the Commission for Air Quality Management (CAQM) shares data showing Delhi’s average AQI for January–May stands at 211 this year. This marks a sharp improvement compared with previous years in the same period, and it is described as the cleanest performance for Delhi during January to May across an eight-year comparison, excluding 2020 from the baseline. The reporting emphasizes that 2020 is treated separately due to unusual conditions during the pandemic, which affected emissions and air quality. The sources consistently cite CAQM as the data provider and focus on the January–May window as the key timeframe for the improvement. No further breakdowns of contributing factors or pollutant-wise changes are provided in the two accounts.
