Paying special attention to the health of countrymen and drawing a strong line on environmental issues the supreme court of India has banned the sale and registration of Bharat Stage III vehicles from 1st of april. It is a major setback to the Indian automotive industry as it has an unsold BS-III vehicles stock of 8.24 lakh units. The decision has been termed as “decision of shock and awe” by the automobile industry. It is clearly stated by supreme court that “on and from April 1,2017 such vehicles that are not BS IV compliant shall not be sold in india by any manufacturer or dealer, that is to say that such vehicles, whether two wheeler, three wheeler, four wheeler or commercial vehicles will not be sold.” Automakers plead to allow them to dispose their existing stock of 8.24 lakh BS III vehicles which was overlooked by the SC stating that the health of millions of people is more important than the commercial interests of the automobile industry.
It further said the manufacturers were fully aware way back in 2010 that BS-IV norms would be enforced from April 1 but they chose to sit back and not take sufficient pro-active steps.
The vehicles compliant with BS III emission norms varies to a great extent from their BS IV compliant engines, depending on the size of the car and whether they are petrol or diesel versions. The difference is majorly in the electronics sensor system, the engine’s ability to process low sulphur fuel and their “after exhaust” system that determines emissions. The center for sciences and environment said that the transition can lead to substantial reductions in particulate matter emissions. For instance, from new trucks, the emission can dip by 80% and from cars by half.
