Haryana’s Dharuhera was India’s most polluted city in October, while Delhi ranked sixth, according to a report by the Centre for Research on Energy and Clean Air (CREA). All ten of the most polluted cities were in the Delhi-NCR region, with Dharuhera recording a PM2.5 level of 123 µg/m³ and Delhi 107 µg/m³. The report said stubble burning caused less than 6% of the pollution, pointing to year-round sources. In contrast, Shillong, Gangtok, and Mysuru were among the cleanest cities. CREA said India’s pollution problem is constant and that reactive, seasonal policies fail to address long-term emission sources. (PC: AFP)
