From April 1, Delhi will be the first city in our country to have fuel that is BS VI complaint. India currently operates on Bharat Stage IV emission norms for two-, three- and four-wheelers.

In a bid to bring down pollution levels and having cleaner cars on the road, the Government has decided to skip directly to BS VI norms by 2020.

This brings India closer to the world as Euro VI emission standards have been in place since 2014 across Europe. It is a bold move, when you look at one of the world’s biggest polluters: America. Vehicular pollution is America’s biggest carbon dioxide source, even as the Environmental Protection Agency (EPA) chief has put scientific evidence aside and said it’s not a cause of global warming. In fact, the EPA governs petrol and diesel vehicles on the same parameters, while Euro and Bharat differentiate between the two.

About Bharat Emission Norms-

The Bharat emission norms that came into force in 1991 for petrol and ’92 for diesel were basic and primarily governed carbon monoxide output from vehicles. India introduced Euro I emission standards in 2000, by which time Europe was already operating at Euro III norms. We have been slower to implement change, primarily due to the costs involved and the quality of fuel available. With India moving on to Euro VI/ BS VI standards, we will finally be at par with Europe and that is quite a feat. For BS VI, the stipulated CO emissions for diesel vehicles is 0.50 g/km and for petrol is 1.0 g/km, NOx is regulated at 0.080 g/km for diesel and 0.060 g/km for petrol, while particulate matter (PM) is set at 0.005 g/km for both. We should see a substantial drop in air pollutants, especially for diesel vehicles, as current BS IV figures are 0.25 g/km NOx for and 0.025 g/km PM.

Note- 

The sulphur content in BS VI fuel is substantially lower than that of BS IV fuel. Currently the sulphur content in our fuel is at 50 parts per million (PPM) while BS VI fuel has a sulphur content of 10 ppm.
