ANSWER: Euro-VI
Explanation:
India is shifting to Euro VI emission compliant diesel and petrol by 2020 to lower carbon pollution. BS-III equivalent to Euro-III specifications is already being followed throughout the country and BSIV will be extended to the entire country. Revised auto fuel policy is also on the cards which will lead to introduction of BS-VI fuels by the year 2020. Oil refineries make investments of up to INR 80,000 crore in upgradation of petrol and diesel quality to get access to cleaner fuel specifications by 2020. Fuels meeting Euro IV or Bharat Stage IV specifications will be supplied by the nation by April 2017 and BS-V or Euro-V grade fuel will be supplied by April 1, 2020 as part of the earlier plan. Now, the government is planning to switch directly from BS-IV to BS-VI. While BS-IV fuels have 50 ppm sulphur, BS-V and BS-VI grade fuel will have 10 ppm sulphur. Oil refineries have upgraded technology and made investments of over INR 55,000 crore for production as well as supply of BS-III/IV fuels. Additional INR 80,000 crore investment is needed for further upgradation.
