From the 10th rank on the 2019 list of the most polluted cities as far as PM2.5 and PM10 are concerned, Kolkata stood at 29 last year. Howrah's rank, on the other hand, has improved from seventh in 2019 to 20. However, both the cities have a long way to go to achieve a 40% reduction in particulate pollution by 2026, which is the revised target set by the Centre recently.
