The Supreme Court E20 ruling has brought India’s ethanol-blended petrol policy into sharp focus, raising questions about its impact on vehicles, consumers, and the environment. India’s journey toward E20 fuel—a petrol blend of 20% ethanol and 80% petrol—has long been debated in the automotive sector, but now it carries legal and policy weight. The judgment comes at a time when India is aggressively pursuing its goal of cutting carbon emissions and reducing dependence on imported crude oil, while also boosting the incomes of sugarcane farmers through increased ethanol demand. Supreme Court E20 Ruling – What Was Decided? The PIL argued that E20 fuel rollout posed risks to older vehicles and consumers who were not given an option to purchase ethanol-free petrol. The petitioner demanded: However, the bench led by Chief Justice B.R. Gavai and Justice K. Vinod Chandran dismissed the petition, siding with the government’s policy. The Attorney General R. Venkataramani defended the rollout, highlighting how it was part of a carefully planned national strategy and pointing out its benefits to farmers, the environment, and energy security. This verdict effectively removes legal obstacles to E20 becoming the standard petrol blend across India. Timeline — How We Got Here Advantages of E20 Fuel After Supreme Court Ruling The court highlighted several advantages of the rollout: Concerns Raised in the PIL While the court dismissed the petition, it did acknowledge the issues raised: The Supreme Court accepted these as challenges but ultimately held that policy benefits outweighed risks.
