Policy action

First generation action has taken roots but the city has yet to meet the clean air standards. Kolkata is making efforts to reduce air pollution – its decision to phase out 15-year-old commercial vehicles from plying within the Kolkata Metropolitan Area and to make a transition from old polluting two-stroke engines to cleaner four-stroke engines running on LPG are steps in the right direction. But much more will have to be done. Policy decisions and action so far in the city
