Environment Minister Prakash Javadekar has informed the Lok Sabha that the government's decision to implement BS-VI norms by 2020 will lead to an overall drop of 50 percent in the emissions of particulate matter by heavy diesel vehicles.
Javadekar stated that in terms of emission benefits, by skipping BS-V and going to BS-VI norms, the estimated drop in pollution by diesel-based heavy duty vehicles is expected to be an 88.5 percent reduction in the oxides of nitrogen (NOx) and a 50 percent reduction in total particulate matter.
The minister has also stated that the cost of the infrastructure needed for the prduction of BS-VI compatible fuels would be Rs. 20,000 crore for petrol and Rs. 60,000 crore for diesel.
