The government has decided to advance the implementation of BS-VI emission norms to 2020. The decision was unanimously taken at an Official meeting consisting the ministers of Transport, Petroleum, Environment, and Heavy Industries.
In India, we currently follow the BS-III norms, which is same as the euro-III regulations. By April 2016, the government is planning to implement BS-IV norms across all the major cities in India, and throughout the country by April 2017.
If these norms are implemented, the oil refineries will have to spend an estimated cost of Rs. 80,000 crore to upgrade the current petrol and diesel quality for meeting the BS-VI emission norms. Previously, oil refineries invested over Rs 55,000 crore to supply BS-III/ IV fuels throughout the country.
