The Swachh Vayu Survekshan 2026 has ranked cities on their efforts to improve air quality, giving residents a way to compare their city’s performance with others. Here is how to check the ranking, understand the categories and interpret what the result actually means.
What is the 2026 Clean Air Survey?
The 2026 Clean Air Survey, officially called Swachh Vayu Survekshan 2026, is an annual assessment conducted under the National Clean Air Programme, or NCAP. The Ministry of Environment, Forest and Climate Change uses the survey to assess the work being done by cities to tackle major sources of air pollution.
The 2026 assessment covered 130 cities across three population categories. These categories are cities with populations above 10 lakh, cities with populations between 3 lakh and 10 lakh, and cities with populations below 3 lakh. The assessment looks at pollution-control measures and the implementation of city-specific clean-air action plans rather than simply ranking cities by their daily AQI.
The results were announced on September 7, 2026, during Swachh Vayu Diwas. Lucknow topped the largest-city category, while Rourkela and Kalinganagar led the two smaller-city categories.
How to check your city’s 2026 clean-air ranking
If you want to find your city’s position, first identify which population category it belongs to. This is important because a city is not necessarily competing against every other city in the country.
For example, a city with more than 10 lakh residents is assessed in Category 1. A city between 3 lakh and 10 lakh falls into Category 2, while a city below 3 lakh is placed in Category 3.
Next, look for the 2026 Swachh Vayu Survekshan results published by the Ministry of Environment and the Central Pollution Control Board. The official government material confirms that all 130 participating cities were assessed and ranked across the three groups.
You can then search the official results using your city’s name. Local news reports are also useful for confirming individual city rankings, particularly for Tier-2 and Tier-3 cities.
Check the correct category before comparing cities
Population category is one of the most important details when reading the ranking.
In the 2026 survey, Category 1 covers cities with populations above 10 lakh. Lucknow finished first in this group, followed by Indore and Jabalpur.
Category 2 covers cities with populations between 3 lakh and 10 lakh. Rourkela in Odisha was the top performer in this group.
Category 3 covers cities with populations below 3 lakh. Kalinganagar in Odisha ranked first in this category.
This means a resident should not simply search for one nationwide ranking and assume that it represents all participating cities. The survey is structured around population groups.
What does your city’s ranking actually measure?
The Swachh Vayu Survekshan ranking is not the same thing as today’s Air Quality Index, or AQI.
This distinction matters.
The survey assesses how effectively cities are implementing measures to address air pollution. The official assessment includes city-specific clean-air action plans and measures aimed at major pollution sources. These include road and soil dust, vehicle emissions, waste burning, construction and demolition activity, industrial pollution and greening measures.
The assessment process involves several stages, including self-assessment by cities, scrutiny by state-level monitoring committees, evaluation by the CPCB, field verification by independent committees and selection of the best-performing cities.
Therefore, a city can receive a strong Swachh Vayu Survekshan ranking even if residents experience poor air on particular days.
Why Nagpur, Indore and other cities can move up or down
The 2026 results show why it is useful to look beyond the final rank.
Nagpur retained 10th position among the large cities, although its score slipped marginally to 183.8. The result means the city continued to perform strongly in the overall assessment despite the slight change in its score.
Indore, which topped the large-city category in the previous survey, moved to second place in 2026. Lucknow took the top position, while Jabalpur secured third place.
The changes show that clean-air rankings can shift from one year to another as cities improve their pollution-control measures and other cities strengthen their own programmes.
Your city’s rank does not tell the whole pollution story
A high position in the clean-air survey should not automatically be interpreted as meaning that the city has completely clean air.
The 2026 results themselves provide an important example. The government said 108 of the 130 NCAP cities recorded lower annual PM10 concentrations in 2025-26 compared with their 2017-18 levels. However, the survey evaluates a broader set of actions and performance indicators rather than relying exclusively on one pollutant measurement.
A Times of India report on the 2026 results also noted that none of the major metropolitan cities met the acceptable PM10 limit during 2025-26, even though some of them performed well in the Swachh Vayu Survekshan because of their scores on other parameters.
This is why residents should use the survey ranking alongside actual AQI and pollutant data when assessing their city’s air.
How to check your city’s current AQI separately
If your goal is to know what the air is like today, check the city’s current AQI rather than relying on the annual Swachh Vayu Survekshan rank.
AQI can change significantly during the day because of weather conditions, traffic, construction activity, dust, industrial emissions and other local factors.
For example, the national pollution picture on September 10, 2026 showed considerable differences between cities. Current AQI listings included cities such as Kaithal and Fatehgarh Sahib among locations reporting higher readings, while Ooty, Kodaikanal and Aizawl were among locations with much lower readings.
So, for everyday decisions such as outdoor exercise, travel or activities involving children and older adults, today’s AQI is more immediately useful than an annual ranking.
What Tier-2 and Tier-3 residents should look for
The 2026 survey is particularly relevant to residents of smaller cities because it does not restrict recognition to major metros.
Rourkela’s first-place finish in the 3 lakh to 10 lakh category and Kalinganagar’s first-place position among cities below 3 lakh show that smaller urban centres are being assessed separately.
The survey also introduced a stronger ward-level focus in 2026. More than 7,400 wards were assessed across the country. At the national level, Ward 70 in Lucknow topped the largest ward category, Wards 30 and 36 in Bhubaneswar topped the middle category, and Ward 13 in Rourkela led the smallest ward category.
For residents, this makes the results more useful because pollution-control work can vary considerably between different parts of the same city.
Takeaways
- Swachh Vayu Survekshan 2026 assessed 130 cities under the National Clean Air Programme.
- Cities were divided into three population groups, so your city should be compared with others in the same category.
- Lucknow topped the above-10-lakh category, Rourkela topped the 3-lakh-to-10-lakh category and Kalinganagar topped the below-3-lakh category.
- The annual clean-air ranking measures pollution-control efforts and implementation, so it should not be confused with your city’s daily AQI.
FAQs
How can I check my city’s Swachh Vayu Survekshan 2026 rank?
Check the 2026 Swachh Vayu Survekshan results released by the Ministry of Environment and CPCB, then search for your city within its applicable population category. Local reports can also help confirm the ranking.
Which city ranked first in India’s 2026 Clean Air Survey?
Lucknow ranked first among cities with populations above 10 lakh. Rourkela topped the 3 lakh to 10 lakh category, while Kalinganagar ranked first among cities with populations below 3 lakh.
Is Swachh Vayu Survekshan the same as AQI?
No. Swachh Vayu Survekshan is an annual assessment of city-level pollution-control measures and implementation. AQI reflects current air pollution conditions based on monitored pollutants and can change from day to day.
Does a high clean-air ranking mean my city has completely clean air?
No. A high ranking indicates stronger performance under the survey’s assessment framework. Residents should also check current AQI and pollutant measurements because annual rankings do not describe the air quality at every location or on every day.
