      Solution

      BIS notified specifications for E22, E25, E27, and E30 fuel blends, setting specifications for petrol mixed with up to 30% ethanol, beyond the current E20 blend target. E22, E25, E27 and E30 refer to petrol blending with ethanol of 22%, 25%, 27% and 30%, respectively. The new standards are expected to reduce India’s reliance on imported crude oil which currently accounts for over 85% of the country’s total requirement.
