Not Delhi, But Ghaziabad Ranks As The Most Polluted City In India; Doctors Warn Of Health Emergency

While Delhi again woke up to a thick layer of haze on Tuesday, December 9, with the AQI remaining in "poor" and "very poor" categories as per the Air Quality Early Warning System for Delhi. A new Centre for Research on Energy and Clean Air (CREA) report released on December 6 noted that it is not Delhi, but Ghaziabad, which is the most polluted city in India, as of November 2025. 

<h2>What Makes Ghaziabad The Most Polluted City In India?</h2>

Ghaziabad remained most polluted city in India, with a monthly average of PM2.5 or particulate matter 2.5 at the concentration of 224 µg/m³. This means Ghaziabad violated the National Ambient Air Quality Standards (NAAQS) on every day of the month as per the CREA's Monthly Air Quality Snapshot. 

Of the entire month, the city experienced 19 "very poor" days, with 10 "severe" days and 1 "poor" day. In the list of top 10, Noida, Bahadurgarh, Delhi, Hapur, Greater Noida, Baghpat, Sonipat, Meerut and Rohtak also joined the list. 

Of the 10 cities, six of them were from Uttar Pradesh, followed by 3 cities from Haryana and then Delhi. All cities except Delhi recorded PM2.5 levels higher than the previous year. 

<h2>What About The Pollution Levels In Delhi?</h2>

The national capital ranked as the fourth most polluted city, recording a monthly average PM2.5 concentration of 215 µg/m³ in November, about twice its October level of 107 µg/m³. The city experienced 23 ʻVery Poorʼ days, six ʻSevereʼ days, and one ʻPoorʼ day throughout November.

Despite widespread pollution, the contribution of stubble burning was comparatively lower this year, an average of seven per cent in November, down from 20 per cent last year. Peak contributions of stubble burning reached 22 per cent, significantly lower than 38 per cent recorded in the previous year.

The analysis drew on real-time continuous ambient air quality monitoring stations (CAAQMS) PM2.5 data.

“Despite a significant reduction in stubble-burning influence, 20 out of 29 NCR cities recorded higher pollution levels than the previous year, and many still did not register a single day within NAAQS limits. This clearly indicates that the dominant drivers are year-round sources such as transport, industry, power plants, and other combustion sources. Without sector-specific emission cuts, cities will continue to breach standards,” said Manoj Kumar, analyst at CREA.

CREA's previous report has highlighted that Delhi’s air pollution almost doubled in November, with average PM2.5 levels touching 215 micrograms per cubic meter. The city recorded 23 days of very poor air, six severe days, and only one poor day. Although stubble burning played a smaller role this year, contributing an average of 7 percent, the pollution remained dangerously high.

Across India, pollution trends were equally worrying. Nine of the ten most polluted cities saw higher pollution levels than last year. Ghaziabad was the worst affected, with PM2.5 levels at 224 micrograms per cubic meter.

According to CREA analyst Manoj Kumar, declining stubble burning shows some progress, but major year round sources such as transport, industry, power plants, and other combustion activities continue to drive the crisis. Without strong emission cuts in these sectors, pollution levels will keep breaching national standards.

<h2>Doctors Warn of a Deepening Health Emergency</h2>

In an interview with ANI, doctors from AIIMS described Delhi’s air quality as a medical emergency. Prof Dr Anant Mohan and Dr Saurabh Mittal from the Department of Pulmonary, Critical Care, and Sleep Medicine said the current situation is now putting vulnerable groups at serious risk, including pregnant women, unborn babies, newborns, and adults with heart or neurological conditions.

Dr Mohan warned that the impacts may be felt for generations. Since the particles are extremely small, they can pass from a pregnant woman to the fetus and interfere with growth. Babies exposed to such conditions in the womb are more likely to be underweight and may have weaker lungs as they grow. Some complications might show up only later in life.

Dr Mittal added that the effects of toxic air go far beyond respiratory illness. Prolonged exposure is increasing cases of breathlessness, lung inflammation, asthma attacks, and chronic conditions like COPD. Fine particulate matter is also entering the bloodstream, raising the risk of heart attacks and strokes.

The growing health concerns underline the need for immediate and coordinated action, making the work of the newly formed expert group even more urgent.
