Delhi experienced its cleanest air on Diwali in eight years, with the air quality index (AQI) at 218, according to the Central Pollution Control Board. This is a significant improvement compared to previous years, with AQIs reaching 312 in 2020 and 431 in 2016. The improved air quality can be attributed to intermittent rainfall and favorable wind speeds that helped disperse pollutants. However, despite a ban on firecrackers, sporadic incidents of burning were reported, and low temperatures could lead to a rise in pollution levels. Stringent restrictions have been implemented under the Graded Response Action Plan.
