Ethanol Blended Petrol Programme: Comprehensive Q&A

The Ministry of Petroleum & Natural Gas has issued this detailed clarification to address ongoing concerns and misinformation regarding India's Ethanol Blended Petrol Programme. The document provides factual and evidence-based responses to frequently raised questions, tracing the programme's 20-year evolution and demonstrating its significant national benefits.

Programme History and Implementation Timeline

India's ethanol blending programme began with a pilot in 2001, was formally announced in 2004, and achieved E5 (5% blending) across several states by 2006. The policy framework was officially notified in the Gazette of India in January 2013 during the UPA government. Despite an initial target of 5% blending across 10 States and Union Territories, blending remained stuck at around 1.5% until 2014 due to production constraints. The programme gained significant momentum with the launch of the National Policy on Biofuels in May 2018, which created a whole-of-government mission involving multiple ministries. A landmark step came in August 2021 when Oil Marketing Companies (IOCL, BPCL, HPCL) issued Expressions of Interest for establishing Dedicated Ethanol Plants in ethanol-deficit regions, offering assured long-term purchase agreements and tripartite financing arrangements.

The blending progression has been deliberate and phased: ESY 2020-21 achieved ~8.1%, ESY 2021-22 reached 10.0%, ESY 2022-23 achieved 12.1%, ESY 2023-24 reached 14.60%, ESY 2024-25 achieved 19.20%, and ESY 2025-26 (November-June 2026) has reached 20% blending. India achieved its 10% blending target in June 2022, five months ahead of schedule, and ultimately achieved the 20% target in 2025—five years ahead of the original 2030 deadline set under the National Policy on Biofuels, 2018.

Economic and Environmental Benefits

The Ethanol Blended Petrol Programme has delivered substantial economic and environmental benefits since ESY 2014-15. The programme has saved over ₹1.97 lakh crore in foreign exchange, substituted nearly 316 lakh metric tonnes of crude oil, reduced approximately 952 lakh metric tonnes of CO₂ emissions, and transferred more than ₹1.66 lakh crore directly to Indian farmers. By June 2025, ethanol production had grown from 38 crore litres in 2014 to 661.1 crore litres, with current production capacity reaching nearly 20 billion litres—well above the approximately 11 billion litres required to sustain the E20 mandate.

The programme has significantly moderated fuel price increases in India compared to other countries. Between June 2022 and June 2026, petrol prices in India increased by only 5.58% (from ₹96.72 to ₹102.12 per liter in Delhi), while diesel prices increased by 6.23% (from ₹89.62 to ₹95.20). This compares favorably to neighboring countries: Pakistan saw petrol prices increase by 39.77% and diesel by 63.18%; Sri Lanka saw increases of 36.66% for petrol and 34.57% for diesel; Nepal saw increases of 20.35% for petrol and 37.81% for diesel; and Bangladesh saw increases of 42.69% for petrol and 26% for diesel.

Vehicle Compatibility and Technical Validation

Extensive testing and stakeholder consultations preceded the E20 rollout. Before finalizing the roadmap, the Government constituted expert committees involving automobile manufacturers, ARAI, SIAM, oil companies, and technical institutions. NITI Aayog published a comprehensive roadmap in June 2021 after extensive consultations with all stakeholders. Every aspect was examined including material compatibility, engine calibration, fuel systems, drivability, durability, emissions, and fuel efficiency.

Real-world evidence confirms vehicle compatibility: Maruti Suzuki serviced 2.84 crore vehicles during FY 2025-26, including 1.5 crore older, non-E20-certified vehicles, and reported no E20-linked corrosion, abnormal wear, or component-life damage. Hero MotoCorp reported similar field experience. While some vehicles may experience a 3-5% reduction in fuel economy, E20 offers a significantly higher-octane rating, superior anti-knock characteristics, faster combustion, better pickup, smoother acceleration, cleaner engine operation, negligible particulate emissions, and approximately 40% reduction in lifecycle carbon emissions compared to pure petrol.

Pricing Structure and Procurement Economics

The Government purchases ethanol at remunerative prices to ensure fair compensation for Indian farmers. The procurement prices for ESY 2025-26 (provisional) are: C-Molasses at ₹57.97/liter, B-Molasses at ₹60.73/liter, Sugarcane Juice/Sugar/Syrup at ₹65.61/liter, Damaged Food Grains at ₹64.00/liter, FCI Rice at ₹60.32/liter, and Maize at ₹71.86/liter. These prices do not include GST, transportation, storage, and depot handling costs. At current international crude oil prices around US$70 per barrel, E20 is actually costlier to produce than pure petrol, but the domestic ethanol component provides insulation from international oil volatility.

Regulatory Framework and Future Direction

From April 2026, all Bharat Stage-VI (BS-VI) vehicles are required to fully meet E20 emission standards, and all petrol sold across India is mandated to contain 20% ethanol meeting a minimum Research Octane Number (RON) of 95. The Government is examining goals beyond the 20% target and considering a phased move towards E25, E27, and E30 blends. On World Environment Day (5 June 2026), the Minister launched E85 flex-fuel promotion, positioning flex-fuel vehicles alongside EVs in India's low-carbon mobility mix. The Global Biofuels Alliance (GBA) was launched on 9 September 2023 on the sidelines of the G20 Summit to foster international cooperation on sustainable biofuels.
