The Indian government informed the Supreme Court that the nationwide implementation of ethanol-blended petrol (E20, containing 20% ethanol) is currently being treated as an experiment, with results expected within the next year. This response came amid concerns raised regarding the potential impact of the increased ethanol blend on engine performance and fuel efficiency. Officials stated the ongoing evaluation will determine the viability and broader rollout strategy for E20. The government emphasized a cautious approach, prioritizing comprehensive data analysis before mandating the higher ethanol content across the country. Concerns were initially raised by petitioners questioning the readiness of vehicle manufacturers and fuel infrastructure for the transition. The court was also informed about measures being taken to address potential challenges related to ethanol availability and supply chain logistics. The government assured the court it is monitoring the situation closely and will provide updates on the progress of the evaluation.
