Jumping a generation and switching to BS VI emission norms directly from BS IV is not feasible, said Vijay Chibber, Secretary, Ministry of Road Transport and Highways, on Wednesday.
Chibber said that the Ministry's internal consultations have revealed that technological issues make leapfrogging BS V norms not feasible.
Asked on his views about the Ministry for Petroleum and Natural Gas planning to squeeze the timeline for implementation of BS VI to 2020, Chibber said, "Oil Ministry should not be one to talk. They are the reason why we are struggling with implementation of BS IV, BS V and BS VI norms. They need to pull up their socks."
Chibber, who was speaking at the sidelines of the 6th annual conference on diesel organised by the Society of Indian Automobile Manufacturers, also said that shifting from BS IV to BS V can be done in a sequential manner but jumping to BS VI requires a different technology.
He added that over this month a decision on the implementation timelines can be taken.
