Supreme Court Upholds Rollout of 20% Ethanol-Blended Petrol

1 September, 2025

The Supreme Court has dismissed a Public Interest Litigation (PIL) that challenged the nationwide rollout of 20% ethanol-blended petrol (EBP-20). The petitioner argued that the fuel was incompatible with many vehicles manufactured before 2023. However, the court rejected the plea after the Attorney General argued that the policy is a sovereign decision that benefits sugarcane farmers. The PIL had sought to make ethanol-free petrol available and mandate clear labeling of ethanol content at fuel pumps.

Unpacked:

Why did the government implement the E20 ethanol-blended petrol policy?

The E20 policy aims to reduce India's dependence on crude oil imports, save foreign exchange, support sugarcane farmers by boosting ethanol demand, and lower carbon emissions through cleaner fuel alternatives.

What concerns have been raised about using E20 petrol in older vehicles?

Concerns include potential mechanical degradation, reduced fuel efficiency, engine corrosion, and higher repair costs for vehicles manufactured before 2023, which might not be fully compatible with E20 fuel.

How has the government addressed concerns about E20 compatibility and vehicle performance?

The government conducted studies through research bodies and committees, concluding that E20 fuel generally does not significantly impact fuel efficiency or insurance validity, and may even improve acceleration and reduce emissions in compatible vehicles.

Are consumers able to access ethanol-free petrol or clearly labeled fuel options?

The dismissed PIL sought mandatory availability of ethanol-free petrol and clear labeling, but the court did not mandate these changes. As a result, such consumer options are not currently guaranteed nationwide.
