Delhi recorded its cleanest July in ten years on Wednesday, with the city's average Air Quality Index (AQI) dropping to 67, according to data released by the Central Pollution Control Board. The reading falls in the 'Satisfactory' category.
So far this year, the capital has seen 118 days of 'Good', 'Satisfactory', or 'Moderate' air quality, a shift from previous years, when 'Poor' to 'Severe' levels were more common during the same period.
Among the monitoring stations, Punjabi Bagh reported the lowest AQI at 50, followed by Bawana (51) and Vivek Vihar (55), all in the 'Good' range.
Environment Minister Manjinder Singh Sirsa called the improvement the result of consistent civic operations and coordination across departments.
"This is not a seasonal blip, it is the result of Delhi's multi-agency implementation model, continuous landfill action, intensified sweeping operations, and a clear commitment to outcome-based governance," Mr Sirsa said.
"We are not celebrating early. We are simply staying the course and the results are becoming visible more frequently across the year," he added.
According to the Delhi government, citywide operations in the last 24 hours cleared 10,987.21 metric tonnes of garbage and lifted 2,349.7 MT of construction and demolition waste. Over 6,000 km of roads were cleaned, and water sprinkling was carried out over 26.35 km.
Legacy waste removal also continues at landfill sites. A total of 923.55 MT was cleared on July 22 - including 487.55 MT from Bhalaswa and 436 MT from Ghazipur.
While the current figures mark a break from the capital's usual air pollution patterns, long-term impact will depend on sustained cleanup, stricter enforcement, and hotspot monitoring in the weeks ahead.
Both CPCB and IQAir follow different methods of calculating air quality index, resulting in different numbers.
Poor air quality is linked to a range of health issues, including respiratory problems, cardiovascular diseases, and aggravated asthma.
That toxic smog around you is driven by spiking particulate matter, vehicle emissions, crop-burning smoke and more.
Delhi air quality: Of the total 38 monitoring stations, 34 were in the 'red zone', indicating 'very poor' to 'severe' air quality.
Despite a 77.5 per cent drop in stubble burning, i.e., agricultural waste - normally a significant reason for air pollution in Delhi during the winter - AQI in the national capital plummeted to a five-year post-Diwali low Tuesday morning.

Friday November 08, 2024हमारी हवा जहरीली हो रही है. गुरुवार की शाम को जब मैं इस मुद्दे पर लिखने बैठी तो AQI लगातार 400 पार जाकर दम घोंट रहा था. बहुत लोगों को यह मामला बोरिंग लगे, लेकिन जब आप अपने साथ काम करने वालों को खांसते-हांफते देखते-सुनते हैं, तो चिंता होने लगती है. सुबह उठते ही दरवाजे खिड़कियां खोलने के लिए डॉक्टर मना कर रहे हैं. बड़े बुजुर्गों के लिए तो मॉर्निंग वॉक बाहर की दुनिया से सीधे संपर्क का ज़रिया है, लेकिन डॉक्टर इसकी भी मनाही कर रहे हैं.
