Swachh Vayu Survekshan 2025 has once again brought to light India’s ongoing battle against air pollution, ranking cities based on their efforts to improve air quality under the National Clean Air Programme (NCAP). The 2025 survey marks a significant step towards understanding how Indian cities are translating clean air policies into measurable actions. Indore, widely celebrated as India’s cleanest city, has once again emerged at the top of the million-plus population category, reaffirming its commitment to cleaner skies despite marginal fluctuations in particulate pollution.

Swachh Vayu Survekshan 2025 and Its Objective

The Swachh Vayu Survekshan 2025 survey focuses on evaluating real actions taken by cities to combat air pollution rather than merely relying on pollutant concentration levels. Conducted under the NCAP, the initiative assesses performance based on how effectively cities implement pollution control measures, introduce green mobility, enhance waste management, and strengthen public participation in air quality improvement efforts.

In the 2025 rankings, Indore reclaimed its top position after slipping to sixth place in 2024, showing consistent improvement in environmental governance and implementation. Jabalpur secured second place, while Agra and Surat shared the third spot. Cities such as Navi Mumbai, Kanpur, Bhopal, and Prayagraj (Allahabad) also found positions within the top ten, demonstrating commendable efforts in reducing pollution levels and enhancing green infrastructure.

Interestingly, major metro cities like Delhi, Mumbai, Bengaluru, and Chennai ranked lower despite reporting certain declines in particulate matter concentrations. This indicates that while metros have begun addressing emissions from vehicles and industries, smaller cities are leading the way in integrated clean air management.

Focus on PM10 Pollution Trends

A central parameter in the Swachh Vayu Survekshan 2025 is PM10 pollution, a significant indicator of air quality that affects public health. PM10 particles, which are tiny dust and smoke particles, can penetrate deep into the respiratory system, posing severe health risks.

Data from the survey revealed that Indore’s PM10 levels rose slightly by 1.2%, from 82 μg/m³ in 2017–18 to 83 μg/m³ in 2024–25. Despite this minor increase, the city’s comprehensive pollution mitigation actions and sustainable waste management practices earned it the highest overall score.

Other cities showed stronger improvements. Chennai, Varanasi, and Bengaluru reported declines in PM10 levels, highlighting effective air pollution management measures. Mumbai recorded the sharpest decline at 44%, followed by Kolkata with 37% and Hyderabad/Bengaluru at 26%. Importantly, 22 cities achieved the National Ambient Air Quality Standards (NAAQS) with PM10 concentrations below 60 μg/m³, with Chennai being the only major metro to meet this benchmark.

Swachh Vayu Survekshan 2025: Rankings Based on Population Categories

The Swachh Vayu Survekshan 2025 classified cities into three distinct population categories to ensure fair comparison and targeted planning.

In the 3–10 lakh population category, Amravati topped the list, followed by Jhansi and Moradabad. Each of these cities demonstrated impressive pollution reduction through enhanced monitoring, improved solid waste management, and citizen engagement.

Among cities with populations below 3 lakh, Dewas took the first position, followed by Parwanoo and Angul. These smaller cities excelled due to localised strategies such as dust suppression drives, better industrial emission control, and increased green cover.

This classification approach allows policymakers to design region-specific clean air strategies, aligning resources and capacity-building efforts with each city’s demographic and industrial context.

Swachh Vayu Survekshan 2025: Government Recognition and Key Initiatives

The Ministry of Environment, Forest and Climate Change (MoEFCC) highlighted that out of 130 NCAP cities, 103 cities recorded a reduction in PM10 levels. Sixty-four cities achieved at least a 20% reduction, while 25 cities managed to reach 40% reductions since the launch of NCAP.

Adding to its clean air credentials, Indore and Udaipur received international recognition under the Ramsar Convention as certified ‘Wetland Cities’ for conserving urban wetlands and promoting eco-friendly development.

To complement the Swachh Vayu Survekshan initiative, the government launched several nationwide campaigns. Among them, the “Ek Ped Maa Ke Naam” initiative aims to plant 75 crore trees during the ‘Seva Parv’ (September 17–October 2) period, enhancing green cover and offsetting emissions across cities. These parallel campaigns not only boost environmental awareness but also foster citizen participation in India’s clean air movement.

Swachh Vayu Survekshan 2025: Ongoing Challenges and Future Outlook

Despite encouraging results, Swachh Vayu Survekshan 2025 also exposed challenges that continue to hinder India’s air quality goals. Many metropolitan cities still record PM10 levels exceeding safe limits, mainly due to vehicular congestion, industrial emissions, and construction dust.

Moreover, experts have raised concerns that the survey’s reduced weighting on actual PM10 reduction allows cities with higher pollution but strong policy frameworks to rank higher. This methodology, while encouraging proactive governance, may not fully capture the true picture of air quality experienced by residents.

To ensure that the survey remains credible and impactful, future editions of Swachh Vayu Survekshan may need to place stronger emphasis on quantifiable air quality improvements alongside implementation scores. Strengthening local air quality monitoring networks, adopting low-emission technologies, and enforcing stricter industrial emission standards are essential to sustain progress.

Nevertheless, Swachh Vayu Survekshan 2025 has successfully created a competitive yet collaborative environment among Indian cities. The recognition motivates urban administrations to pursue cleaner air, greener cities, and a healthier future for citizens. With growing public awareness and government support, India’s clean air mission under NCAP is steadily transforming from vision to action.
