The report analyses data of the pollution levels in 17 Indian cities provided by the National Air Quality Index (NAQI).

According to the report, as many as 15 of the 17 Indian cities with NAQI stations showed levels of air pollution that far exceed prescribed Indian standards. The high pollution figures recorded for well over 50% of the days that data was recorded between April and November indicate the continuing severity of air pollution, it said.

“As the political capital—and indeed, the most polluted of all cities— the bad air in Delhi gets the most attention. But scratch below the murky surface and you will find concentrations of PM2.5 in several other cities—Lucknow, Ahmedabad, Muzzafarpur and Faridabad, among others—that would justify the triggering of a ‘red alert.’ Even the government’s own, largely inadequate NAQI data reveals that 23 of the 32 stations across India have PM 2.5 levels that exceed the national standards,” said Sunil Dahiya, campaigner, Greenpeace India.
