The Supreme Court on Aug 31 hears a plea for mandatory ethanol percentage disclosure at petrol pumps, a case that could reshape E20 blending rules and hit auto, oil stocks.
The Supreme Court will hear a petition on August 31 that seeks mandatory disclosure of ethanol content in petrol at every dispensing nozzle. The plea, filed by Narendra Kumar Goswami, asks the court to direct the Centre and others to ensure uniform labelling at petrol pumps showing the exact ethanol percentage. The case will come before a bench of Justices M M Sundresh and Prasanna B Varale, according to the apex court's causelist.
The petition also demands that every fuel invoice should state the ethanol percentage legibly. It calls for a public database searchable by manufacturer, model, engine type, and year of manufacture to indicate vehicle compatibility with various ethanol blends. The plea seeks an independent expert committee to examine real-world compatibility of E20 across the existing fleet. That committee, the petition says, should also study fuel efficiency, engine longevity, maintenance costs, warranty and insurance implications, and the net environmental footprint of ethanol production, including water consumption and food-security concerns.
The petition asks the court to direct authorities to frame a national consumer disclosure protocol for ethanol-blended petrol in consultation with the Central Consumer Protection Authority and the Bureau of Indian Standards. It also seeks all policy files, technical studies, compatibility reports, safety standards, and consumer advisories that support the compulsory roll-out of E20. The plea calls for a transparent transition framework for legacy and non-compatible vehicles, including designated availability of lower ethanol petrol where feasible.
The hearing could determine whether the government's E20 blending programme faces additional consumer-disclosure obligations. Oil marketing companies and auto manufacturers that have already invested in E20-compatible engines may need to adjust their labelling and communications if the court mandates uniform disclosure. The bench is scheduled to take up the matter on August 31.
