The survey was done by Central Pollution Control Board (CPCB) covering 131 cities under the National Clean Air Programme (NCAP).
The ranking is based on key parameters such as reduction in particulate matter (PM10), road dust control, waste management, monitoring infrastructure, public awareness, and institutional capacity.
A senior official from district administration attributed the Swacch rank ti interventions such as improved waste segregation and door-to-door collection, mechanised road sweeping, among others.
The city also enforced stricter control on open waste burning, he said. Expansion of green spaces and stronger community participation further supported the government’s clean air initiatives, bringing down PM10 level from 88 in 2017-18 to 53 in 2025-26.
