Critics say artificially lowered pollution readings give a false impression that the city’s campaign against pollution is working effectively, masking the government’s failure to curb the menace.

There is a new worrying development: another “smog” is hovering over the veracity of New Delhi’s pollution readings.

A major investigation has revealed a critical failure in Delhi's air pollution monitoring system. Two-thirds of the national capital does not have access to reliable, real-time air quality data.

Delhi has 38 air quality monitors, but their placement leaves out 65% of the national capital without reliable air quality estimates.

The national capital Delhi woke up to a cold and foggy Monday morning, with the minimum temperature recorded at 10 degrees Celsius.

According to the monthly data, the last time Delhi logged a cooler November was in 2020, when the average minimum was 10.3°C.

BMC litter-picking machines, meant to keep the city clean, are now being criticised. Critics allege that these very machines are kicking up harmful road dust, worsening Mumbai's already poor air quality.

The Commission for Air Quality Management (CAQM) is launching PAVAN — Platform for Air Quality Vigilance and Analytics for NCR, a new digital ecosystem designed to transform inspections, compliance monitoring, and enforcement across the region.

A day after the Graded Response Action Plan’s (GRAP-III) restrictions were lifted, Delhi’s air quality slipped back into the higher end of the very poor category. The air quality index (AQI) stood at 377, compared to 327 a day earlier, even as authorities said restrictions would be re-imposed if pollution levels worsened.

Rohatak has seen a sharp increase in heavily polluted days this year, rising from 7 last year to 16 this year. However, farmers have burnt 37 per cent less stubble compared to the previous season, as they try to reduce pollution levels.

Revoking Stage III restrictions may give a false sense of security, as 'severe' AQI persists in parts of Delhi.

Delhi AQI data gap explained: The world’s most polluted capital city is still largely flying blind when it comes to understanding the full scope of the toxic air its residents breathe.

Delhi's air quality worsened to "very poor" after Stage-3 restrictions were lifted, with an AQI of 381, raising concerns over fluctuating pollution measures.

A new analysis shows that most of Delhi’s 39 air quality monitoring stations are located in south and central areas, leaving large parts of the city — especially the outskirts — without proper pollution tracking. Experts say this imbalance makes it hard to understand true pollution levels and plan effective action.

A new report shows that Delhi’s air quality monitoring stations are unevenly spread, with most located in the south and central parts of the city. Large peripheral areas remain under-monitored, affecting efforts to track pollution accurately and plan effective responses.
