Gasoline

The Indian government introduced vehicles exhaust emission regulations in 1991. They were tightened in 1996, indirectly mandating the use of catalytic converters.

On April 1, 2020, the Bharat Stage (BS) VI emission standards (equivalent to the Euro 6/VI emission standards) were implemented nationwide. The switch from BS IV to BS VI was started in the National Capital Territory of Delhi from April 1, 2018, then followed by the National Capital Region1) from April 1, 2019. The table below shows the current emission limits under BS VI for light-duty gasoline vehicles in India.
