India will get world's cleanest fuel from April 1 by switching to BS VI fuel

India will switch to the world’s cleanest fuel from April 1, 2020. When it moves to Bharat Stage VI-compliant petrol and diesel. India will be among countries where sulphur in fuel Is capped at 10 parts per million (PPM). The country in 2010 adopted to BS III fuel with Sulphur contents of 150 ppm (petrol) & 350 ppm (diesel). BS-IV, introduced 7 years later, cut it down to 50 ppm for both. Adopting BS-VI will help in curbing particulate matter in the air. Most refineries started producing BS-VI fuel in April 2019: Indian Oil Corp. State-owned refineries spent ~Rs 35,000 crore to upgrade to produce ultra-low sulphur fuel. The new fuel will cut nitric oxides in BS VI-compliant vehicles by 25% in petrol engines and 70% in diesel ones.
