In a major decision, the Supreme Court has said that only Bharat Stage VI (or BS-VI) vehicles shall be sold across the country from April 1, 2020.
This implies that no BS-IV or BS-VI non-compliant vehicles can be sold after this deadline.
It need be mentioned that the Bharat stage emission standards (BSES) are instituted by the government to regulate output of air pollutants from motor vehicles.
It was back in year 2016 that the centre had announced that the country would skip BS-V norms and adopt BS-VI norms by 2020.
The automobile manufacturers had justified the grace period saying India was attempting to jump from BS-IV emission norms to BS-VI in a short span of time.
BS-VI grade petrol and diesel, billed as “ultra-clean” fuel, became available in Delhi from April this year. The fuel helps even current generation vehicles cut particulate emissions by 10 to 20 per cent.
The move to phase out BS-IV and promote use of clean fuel is aimed at lowering the alarming levels of air pollution in the national capital, among the world’s most-polluted megacities.>
