Solution
The Indian government has made it a requirement to mix 5% ethanol with petrol as a measure to decrease vehicle exhaust emissions and to alleviate the dependence on imported crude petroleum, which is the source of petrol production. This blending of ethanol with petrol was initiated in 2001 and is facilitated by the fact that ethanol is a by-product of the sugar industry and can be obtained at cost-effective rates. Additionally, this practice helps in reducing the consumption of petroleum in the transportation sector, thereby contributing to the reduction of greenhouse gas emissions.
