BS VI Fuel Current Affairs
Delhi became the first city in India to supply ultra-clean Bharat Stage (BS) VI grade fuel (both petrol and diesel) with an aim to combat the rising levels of air pollution in Delhi-NCR region. State-owned oil firms have started supplying the BS-VI fuel (equivalent to fuel meeting Euro-VI emission norm) at all their 391 petrol pumps in NCT.
Other cities in NCR like Noida, Gurugram, Ghaziabad and Faridabad as well as other 13 major cities, including Mumbai, Chennai, Bengaluru, Hyderabad and Pune will roll-out cleaner BS-VI grade fuel from January 1 2019. However, BS-VI fuel will be rolled out in rest of the country by April 2020. By switching to BS-VI, India will join league of US, Japan and European Union, which follow Euro Stage VI emission norms.
The Union Government in October 2016 had decided to skip one stage and migrate to BS-VI directly from BS-IV from April 2020 to fight the growing pollution. The deadline for it in Delhi was brought forward to 2018 due to higher level of pollution i.e. thick toxic smog faced in winter season. It was part of concerted efforts of Government to reduce vehicular emissions and improve fuel efficiency with an aim to reduce carbon footprints and keep environment healthy.
Benefits of BS-IV fuel
The major difference in standards between the existing BS-IV and new BS-VI auto fuel norms is presence of sulphur. BS-IV fuels contain 50 parts per million (ppm) sulphur, while BS-V and BS-VI grade fuel will have 10 ppm sulphur. Thus, newly introduced BS VI fuel is estimated to reduce amount of sulphur released by 80%. It will also bring down the emission of NOx (nitrogen oxides) from diesel cars by nearly 70 % and 25% from cars with petrol engines. It will also bring down cancer causing particulate matter emissions from diesel engine cars by phenomenal 80%.
