Kolkata - Post Report Question and Answers
Pollution index (Good, Moderate, Unhealthy, or Very Unhealthy)?
Unhealthy to very unhealthy. This city is huge, has tons of cars, and all the cars are old -- as are the busses and auto rickshaws. Kolkata is the last city to phase out the really polluting vehicles for CNG (natural gas) and can't enforce the laws, so we have all the old vehicles from the other cities. - Jun 2009
Very, very, very unhealthy. - Mar 2009
Very unhealthy -- Calcutta has the worst pollution index of all the major cities in India. - May 2008
