New Delhi, July 24, 2025 – Delhi has achieved a remarkable milestone, recording its cleanest July in ten years with an average Air Quality Index (AQI) of 67, falling in the ‘Satisfactory’ category, according to the Central Pollution Control Board (CPCB). This significant improvement in air quality marks a shift from previous years, offering residents a breath of fresh air during the monsoon season.

Key Highlights of Delhi’s Air Quality in July 2025

• Lowest AQI in a Decade: Delhi’s average AQI dropped to 67 on Wednesday, July 23, 2025, the cleanest July recorded in ten years.
• Monitoring Stations Report ‘Good’ AQI: Punjabi Bagh recorded the lowest AQI at 50, followed by Bawana at 51 and Vivek Vihar at 55, all in the ‘Good’ range.
• 118 Days of Cleaner Air: So far in 2025, Delhi has seen 118 days of ‘Good’, ‘Satisfactory’, or ‘Moderate’ air quality, a stark contrast to the ‘Poor’ to ‘Severe’ levels common in previous years.
• Sustained Civic Efforts: Environment Minister Manjinder Singh Sirsa credited the improvement to Delhi’s multi-agency implementation model, including continuous landfill action, intensified sweeping operations, and outcome-based governance.

Why Delhi’s Air Quality Improved

The cleaner air in July 2025 is attributed to a combination of favorable weather conditions and sustained civic efforts:

• Monsoon Rainfall: Recent rainfall has played a significant role in reducing air pollution levels, with Delhi witnessing wet weather in July.
• Coordinated Efforts: The Delhi government’s initiatives, including daily clean-up drives and the removal of 10,987.21 metric tonnes of garbage and 2,349.7 metric tonnes of construction waste in the last 24 hours, have contributed to cleaner air.
• Policy Implementation: A year-round ban on firecrackers and intensified pollution control measures have helped maintain air quality in the ‘Satisfactory’ range.

What Does an AQI of 67 Mean?

According to the CPCB, an AQI between 51 and 100 is classified as ‘Satisfactory,’ indicating minimal health risks for the general population. This is a significant improvement from the typical July AQI range of 90–150 in previous years.

Looking Ahead: Sustaining Delhi’s Clean Air

While the monsoon season naturally aids in reducing pollution, experts emphasize the need for consistent efforts to maintain this progress, especially as winter approaches, when air quality often deteriorates due to stubble burning and thermal inversion. Delhiites are hopeful that the government’s commitment to pollution control will ensure cleaner air year-round.
