Why in News?
The Karnataka government has said that petrol samples collected from outlets of major oil marketing companies (OMCs) in six districts contained ethanol well above the prescribed 20% limit, with one sample recording as high as 31.2%. The State has also alleged that in-house laboratories of the oil companies did not disclose ethanol content in their test reports, raising questions of transparency in the sale of ethanol-blended petrol across the country.
What did the Karnataka Tests Find?
Samples were drawn by the State’s Department of Legal Metrology from Bengaluru Urban, Bengaluru Rural, Kolar, Chikkaballapura, Tumakuru and Dakshina Kannada districts and later re-tested at NABL-accredited laboratories.
| Oil company | Ethanol content reported in sample | Deviation from E20 norm |
|---|---|---|
| Indian Oil Corporation Ltd (IOCL) | 31.2% | +11.2 percentage points |
| Hindustan Petroleum Corporation Ltd (HPCL) | 30.5% | +10.5 percentage points |
| Bharat Petroleum Corporation Ltd (BPCL) | 26.5% | +6.5 percentage points |
| Nayara Energy | 26.1% | +6.1 percentage points |
| Shell | 25.5% | +5.5 percentage points |
Note: Figures as claimed by the Karnataka government; the oil companies’ response and independent verification are awaited.
What is the Ethanol Blended Petrol (EBP) Programme?
- About: Launched in 2003, the EBP Programme mandates OMCs to sell petrol blended with ethanol, an alcohol produced mainly from sugarcane and grain-based feedstocks.
- Nodal ministry: Ministry of Petroleum and Natural Gas (MoPNG).
- E20: Petrol containing 20% ethanol and 80% petrol. India achieved the 20% blending milestone in July 2025, ahead of the original 2030 timeline.
- Ethanol Supply Year (ESY): Ethanol procurement by OMCs is tracked over a supply year running from November to October.
- Feedstocks: C-heavy and B-heavy molasses, sugarcane juice/syrup, damaged food grains, maize and surplus rice; second-generation (2G) ethanol can use crop residue such as rice straw.
Policy Framework
| Policy / Scheme | Key provisions |
|---|---|
| National Policy on Biofuels, 2018 | Expanded permissible feedstocks for ethanol; set an indicative 20% blending target by 2030. |
| Amendment to the Biofuel Policy, 2022 | Advanced the E20 target from 2030 to ESY 2025-26. |
| Pradhan Mantri JI-VAN Yojana, 2019 | Viability gap funding for second-generation (2G) bio-ethanol projects using lignocellulosic biomass. |
| Roadmap for Ethanol Blending in India 2020-25 (NITI Aayog) | Laid out the pathway for E20, including vehicle compatibility, fuel efficiency and supply-side measures. |
| Interest subvention schemes for distilleries | Support for new and expanded grain- and molasses-based ethanol capacity. |
Why is Ethanol Blending Important?
| Dimension | Benefit |
|---|---|
| Energy security | India imports over 85% of its crude oil requirement; ethanol substitutes part of the petrol demand with a domestic fuel. |
| Foreign exchange | Government estimates put forex savings since 2014-15 at over ₹1.3 lakh crore. |
| Farmers’ income | Payments by OMCs to distillers support timely clearance of sugarcane dues and create demand for maize and surplus grain. |
| Emissions | Ethanol burns cleaner, cutting carbon monoxide and hydrocarbon emissions; it supports India’s net-zero 2070 pathway. |
| Waste to wealth | 2G ethanol from crop residue can reduce stubble burning in north India. |
What are the Concerns?
- Quality and transparency: Blends far above 20% suggest weak quality control at depots and inadequate disclosure of ethanol content in test reports.
- Vehicle compatibility: Many older vehicles were designed for E5 or E10. Ethanol is hygroscopic and can corrode rubber seals, fuel lines and some metal parts if materials are not compatible.
- Fuel efficiency: Ethanol has lower energy density than petrol. NITI Aayog’s roadmap estimated a mileage drop of about 6–7% for four-wheelers designed for E0 and calibrated for E10, when run on E20.
- Consumer pricing: Consumers have questioned why E20 is not priced lower despite lower energy content and cheaper ethanol procurement.
- Food vs fuel: Diversion of sugarcane, maize and rice for ethanol may affect food and feed availability and prices.
- Water stress: Sugarcane is water-intensive; heavy reliance on it can worsen groundwater depletion in States like Maharashtra and Karnataka.
Way Forward
- Mandatory labelling: Display the exact ethanol percentage at fuel pumps and on bills, and publish test results of OMC labs.
- Independent testing: Periodic third-party sampling by NABL-accredited labs, with penalties for deviation from BIS fuel standards.
- Protect consumers: Offer an E10/premium option for older vehicles and issue clear advisories on compatibility and warranties.
- Diversify feedstock: Scale up 2G ethanol from agricultural residue and promote less water-intensive crops such as maize and millets.
- Flex-fuel transition: Encourage flex-fuel and E20-compliant vehicles before considering blends beyond 20%.
Conclusion
The early achievement of E20 is a major step towards energy self-reliance, but the Karnataka findings show that the next phase must focus on quality, transparency and consumer trust. A credible testing and labelling regime is essential before India moves towards higher blends.
