Although the authority of the Indian government to set vehicle emissions standards was codified in 1988, it was in 2003 that India implemented the Bharat standards, which parallel the Euro standards. India currently applies the equivalent of Euro 4/IV to new light-duty, heavy-duty, and two- and three-wheeled vehicles, and will introduce the equivalent of Euro VI for all new on-road vehicles in 2020. Previous Bharat standards were introduced earlier in select major cities. India has also adopted nationwide fuel efficiency standards for light-duty vehicles.
