Swachh Vayu Survekshan 2025: Chennai’s Struggle To Clear The Air Exposed

The latest Swachh Vayu Survekshan 2025 report by the Ministry of Environment, Forest and Climate Change (MoEF&CC) has placed Chennai at the bottom among all million-plus cities in India for air quality management. This annual ranking assesses cities based on their efforts and effectiveness in controlling air pollution and implementing sustainable clean air measures under the National Clean Air Programme (NCAP).

 

Key Highlights Of Chennai’s Ranking

Chennai ranked 41st out of 41 cities with a score of 115.3, far behind the top city Indore, which secured a perfect score of 200

 

The survey evaluated 130 cities in total, analyzing parameters like road dust control, vehicular and industrial emissions, construction dust, solid waste burning, and public awareness

 

While parts of Tamil Nadu showed mixed results, Tiruchirappalli stood out with a 9th position in the million-plus category, making Chennai’s position even more stark

 

Madurai fared only slightly better, ranking 40th with 116.1 points, while smaller cities like Thoothukudi ranked low among their peers as well

 

Report points to persistent challenges in managing vehicular emissions, construction dust, and solid waste in Chennai despite substantial funds allocated under NCAP

 

The city received Rs 474.65 crore under NCAP funding and utilized Rs 384.76 crore, mainly on solid waste collection with limited progress on road dust control

 

Metro construction and urban development have contributed to increased dust levels; manual sweeping practices still create pollution rather than mitigate it

 

Underpinning Causes And Expert Views

Rapid urbanization, high dependence on private vehicles, poor public transport integration, and ineffective enforcement of environmental regulations have exacerbated pollution. Experts from IIT Madras emphasize the urgent need for rapid electrification of vehicles, strict dust control at construction sites, investment in mechanized road cleaning, and incentivizing green public transport use to reverse the deteriorating air quality trend.

 

Government And Administrative Response

Chennai Municipal Corporation and related agencies have pledged ongoing efforts including expanding green belts, stricter monitoring of industries, and public awareness campaigns. However, activists argue that these measures need accelerated execution combined with stronger policy reforms and technological interventions to bring meaningful improvement in air quality.

 

Implications For Residents And Businesses

Poor air quality severely impacts public health, with rising respiratory diseases and decreased life quality for residents. Business operations are also affected due to worker health issues and regulatory risks. Enhancing air quality management is vital not only for health but also for economic productivity and sustainable urban living.

 

Way Forward: Strategic Priorities For Chennai

Conclusion

Chennai’s last-place finish in the Swachh Vayu Survekshan 2025 ranking serves as a wake-up call for policymakers, civic agencies, and citizens alike. The path to cleaner air demands urgent collaborative action, blending regulatory enforcement, cutting-edge technology, public participation, and sustainable urban planning. As one of India’s largest metropolitan cities, Chennai must strive to reclaim its position as a healthy and environmentally responsible urban center to ensure a better quality of life for millions.
