The air in Delhi sucked a little less last year. Official data shows the city recorded its best average air quality and particulate pollution levels in seven years during 2025, only underperforming compared to the anomalous COVID lockdown year. The Commission for Air Quality Management credited sustained policy actions and field-level coordination for the improvement, noting 79 days rated Good or Satisfactory on the Air Quality Index, a figure only surpassed in 2020.
Challenging winter weather still caused a spike, with an average AQI of 351 in December, yet the year saw only eight Severe pollution days, far fewer than the twenty-five recorded back in 2019. Key months like February and July hit their lowest average AQI since tracking began in 2018. The overall annual AQI average settled at 201, with daily PM10 concentrations dropping to 197 micrograms per cubic meter and PM2.5 levels falling to 96 micrograms per cubic meter, both marking clear declines from previous years.
Officials stated these gains result from persistent enforcement and targeted anti-pollution strategies across short and long term horizons, expecting continued gradual improvement. While experts warn that problematic winter smog persists, the structural measures appear to be yielding measurable, positive results for the capital's filthy atmosphere.
