India's biofuel drive is saving billions but also sparking worries

India's push for biofuel integration has reduced carbon emissions by millions of tonnes and saved billions of dollars in foreign exchange reserves. However, concerns have arisen over the impact on fuel efficiency and food security. While the government sees ethanol blending as vital for emissions reduction, some worry about potential mileage decreases and engine damage. Manufacturers like Maruti Suzuki are offering solutions to mitigate these concerns, but skepticism remains among some vehicle owners in India.
