The Supreme Court on Monday (September 1, 2025) dismissed a petition challenging the nationwide rollout of 20% ethanol-blended petrol (E20), which alleged that millions of motorists were being compelled to use fuel unsuited to their vehicles without the option of availing ethanol-free petrol.

A Bench of Chief Justice of India (CJI) B.R. Gavai and Justice K. Vinod Chandran refused to entertain the petition after the Union government defended the ethanol-blending programme as a measure to bolster the income of sugarcane farmers and conserve foreign exchange.
