Byrnihat and Begusarai are the most polluted cities in India in 2023, according to a report released by an independent think tank. The report also reveals that Greater Noida is among the top three polluted cities. The data shows that 78 out of 85 cities included under the National Clean Air Programme have exceeded the prescribed air quality standards. The government aims to achieve a 40 percent reduction in particulate matter concentration in these cities by 2026. Only 37 NCAP-covered cities have achieved PM10 levels below the annual targets.
