According to a recent report by Greenpeace India, ten cities, including Bengaluru, Mangaluru, and Mysore, have seen significant levels of pollution despite the implementation of covid restrictions. Greenpeace India reached this conclusion based on data from the Central Pollution Control Board from November 2020 to November 2021. According to the report, pollution levels in these cities are far higher than the World Health Organization’s standards.
Air quality (PM 2.5) levels in Coimbatore, Bengaluru, Mangaluru, and Amravati are six to seven times higher than WHO limits. Particulate matter levels are four to five times higher in Mysuru, Kochi, Chennai, and Puducherry. Air pollution has worsened not only in north but also in south India. When lockdown was implemented, air pollution was supposed to decrease. The ten cities chosen for the study, however, had substantially higher levels of PM 2.5 and PM 10 than the national average, according to the paper. Mangaluru, Amravati, Chennai, and Kochi have three to four times higher pollution levels than the national average, while Mysuru, Coimbatore, Puducherry, and other cities have two to three times higher pollution levels.
