Delhi experienced a significant improvement in air quality during April 2024, as per official data.

The city made a record of the maximum number of ‘Good to Moderate’ air quality days as compared to the corresponding period of the last six years, starting from 2018 (excluding 2020 due to the lockdown enforced as a response to the Covid-19 pandemic).

The national capital registered only seven days with an Air Quality Index (AQI) exceeding 200 in April 2024. This marks a noteworthy reduction when compared to previous few years.

In addition to this, the average AQI during April 2024 was considerably low, making the month the second-best in terms of air quality since 2018.

This improvement may largely be credited to efficient air pollution control measures taken by the government, along with favourable weather conditions, the data suggested.

An AQI between 0 and 50 is considered ‘Good’, 51 and 100 ‘Satisfactory’, 101 and 200 ‘Moderate’, 201 and 300 ‘Poor’, 301 and 400 ‘Very Poor’, and 401 and 500 is considered ‘Severe’.

Furthermore, April 2024 marked a significant reduction in daily average concentrations of particulate matter, PM2.5 and PM10, as compared to the corresponding periods in the previous years.
