An official notification has been issued by Ministry of Road Transport and Highways (MORTH) for the implementation of Bharat Stage VI emission norms from April 1, 2020. In February, the government had invited suggestions about the new emission norms and the automotive companies had requested to delay the timeline as more time would be needed to implement the change. According to Society of Indian Automotive Manufacturers (SIAM) an investment of Rs. 1.5 lakh crore will have to be made by the automotive industry for meeting the requirements within the stated deadline. But the government has still not postponed the plans.
According to the Delhi-based green body, Centre for Science and Environment (CSE), if BSVI norms are implemented then there would be reduction of 89% in the particulate matter emissions and 76% Nox from two-wheelers and a reduction of 82% in PM emissions and 68% in NOx emissions from cars. PEMS (portable emissions monitoring systems) are being implemented for real time monitoring of the on-road vehicles.
