Average April AQI in capital worst since 2022

According to data from the Central Pollution Control Board, Delhi's air quality in April 2025 has been the poorest for that month since 2022.

• The Data: The average Air Quality Index (AQI) for April up to the 27th has reached 269, which falls into the "poor" category. This is worse than the average for April in both 2023 and 2024.

• The Trend: This marks a significant downturn, as the previous two Aprils had shown a trend of gradual improvement. Experts cited in the article suggest that an increase in local pollution sources, particularly waste burning, is a major contributor to this decline.

• The Implication: The data indicates that gains made in recent years are fragile and can be quickly reversed. It underscores that without consistent, year-round action on local emissions, Delhi's air pollution crisis remains severe.
