BIS Approves New Fuel Standards for Higher Ethanol-Blended Petrol

Bureau of Indian Standards has officially notified fuel specifications for higher ethanol-blended petrol variants, including E22, E25, E27, and E30 fuels, marking a major advancement in India’s ambitious ethanol blending and clean energy programme.

According to a government notification dated May 15, 2026, the Bureau of Indian Standards (BIS) introduced standard IS 19850:2026 for “E22, E25, E27 and E30 Fuel, Admixture of Anhydrous Ethanol and Motor Gasoline for Usage in Positive Ignition Engine Powered Vehicles.”

The notification establishes formal technical specifications for higher ethanol fuel blends and is expected to provide much-needed regulatory clarity for automakers, oil marketing companies, and biofuel producers as India intensifies efforts to reduce dependence on imported crude oil and transition toward cleaner transportation solutions.

India Accelerates Ethanol Blending Roadmap

Push for Cleaner and More Sustainable Fuels

India has been aggressively promoting ethanol blending as part of its broader strategy to improve energy security, reduce carbon emissions, and support domestic agriculture and biofuel industries.

Ethanol, which is primarily produced from sugarcane, maize, and other agricultural feedstocks, is considered a cleaner-burning alternative to fossil fuels. Blending ethanol with petrol helps lower greenhouse gas emissions while reducing the country’s reliance on imported crude oil.

The latest Bureau of Indian Standards (BIS) notification comes at a time when India is rapidly scaling up its ethanol blending programme after achieving significant progress under the Ethanol Blended Petrol (EBP) initiative. The government has consistently highlighted ethanol adoption as a key component of its green mobility and climate strategy.

Understanding E22 to E30 Fuel Blends

The newly notified standards cover:

• E22 petrol containing 22% ethanol
• E25 petrol containing 25% ethanol
• E27 petrol containing 27% ethanol
• E30 petrol containing 30% ethanol

These higher blends represent the next stage beyond India’s current ethanol blending targets and could pave the way for even more advanced biofuel adoption in the future.

Industry Welcomes BIS Notification

AIDA Calls the Move “Significant and Timely”

The All India Distillers' Association (AIDA) welcomed the government’s decision, calling it an important milestone for India’s ethanol ecosystem.

Reacting to the notification, Vijendra Singh, President of AIDA, described the move as a major boost for the country’s long-term energy and sustainability goals.

“The publication of BIS standards for E22 to E30 fuels is not just a technical notification but a progressive and forward-looking step that reinforces the Government’s long-term commitment towards higher ethanol adoption, reduced crude oil dependence, and a cleaner mobility ecosystem,” said Vijendra Singh, President of AIDA.

The industry body believes the formal introduction of higher ethanol fuel standards will encourage investments across the biofuel value chain while supporting domestic ethanol producers.

E25 Fuel Standards Could Help Sugar and Ethanol Industries

Addressing Surplus Production Challenges

AIDA particularly welcomed the introduction of E25 fuel standards, stating that the move could help absorb excess sugar and ethanol production capacities currently available in the Indian market.

India’s sugar industry has often faced challenges related to surplus production, fluctuating global prices, and inventory management. Increased ethanol blending is viewed as an effective solution to channel surplus sugarcane production into fuel manufacturing, thereby stabilizing farmer incomes and improving industry profitability.

Industry experts believe that higher ethanol blending could create long-term demand stability for domestic ethanol producers while reducing the financial stress faced by sugar mills.

Focus Shifts Toward E85 and E100 Fuels

Flex-Fuel Vehicles Expected to Play a Key Role

While welcoming the new standards, AIDA also emphasized that India’s long-term ethanol strategy should eventually move toward even higher ethanol blends such as E85 and E100 fuels.

The association highlighted the importance of flex-fuel vehicles (FFVs), which are specifically designed to operate on multiple ethanol-petrol blend combinations.

“FFVs can play a transformational role in enabling higher ethanol consumption, strengthening energy security, reducing emissions, and creating a sustainable long-term market for domestic biofuels,” Singh added.

Flex-fuel technology has already seen large-scale adoption in countries such as Brazil, where ethanol-powered transportation has significantly reduced dependence on conventional fossil fuels.

Automakers Preparing for Future Ethanol Standards

The BIS notification is expected to help automakers align future vehicle designs with higher ethanol compatibility standards. Industry analysts believe the regulatory clarity provided by the government could encourage automobile manufacturers to accelerate the development of ethanol-compatible engines and FFV models in India.

Oil marketing companies are also likely to begin upgrading fuel infrastructure and supply chains to accommodate higher ethanol blends in the coming years.

India’s Broader Green Mobility Vision

Reducing Crude Oil Dependence

India remains one of the world’s largest crude oil importers, making energy security a critical national priority. By increasing ethanol blending levels, the government aims to reduce import dependence while lowering the country’s fuel import bill.

Higher ethanol adoption also aligns with India’s climate commitments and efforts to achieve cleaner transportation systems under various sustainability initiatives.

The expansion of ethanol-based fuels is expected to complement India’s parallel push toward electric mobility, biofuels, compressed biogas, and hydrogen-powered transportation technologies.

Conclusion

The BIS notification introducing standards for E22, E25, E27, and E30 petrol blends marks a major milestone in India’s evolving biofuel and clean mobility strategy. By formally establishing specifications for higher ethanol blends, the government has laid the groundwork for the next phase of ethanol adoption in the country.

The move is expected to benefit multiple sectors, including agriculture, sugar production, biofuel manufacturing, and automobile industries, while also helping India reduce crude oil imports and lower emissions. Industry bodies such as AIDA view the development as a strong signal of the government’s long-term commitment to sustainable fuel alternatives.

As India continues expanding its ethanol blending programme, the focus may increasingly shift toward higher blends like E85 and E100, supported by the growth of flex-fuel vehicles and advanced biofuel infrastructure. The latest BIS standards could therefore become a crucial foundation for India’s transition toward cleaner, more energy-secure transportation systems.
