India's Ethanol Blending Programme: Achievement and Impact

The Ministry of Petroleum & Natural Gas has published a detailed Q&A document defending India's ethanol blending programme and celebrating the achievement of its 20% blending target (E20) five years ahead of the original 2030 schedule. The document outlines the historical context, economic benefits, and technical validation behind the programme.

Programme History and Gradual Implementation

The ethanol blending initiative has a long institutional history, beginning with a pilot programme launched in 2001 and a formal announcement in 2004. E5 (5% ethanol blending) was rolled out across several states by 2006, and the policy framework was notified in the Gazette of India in January 2013 during the UPA government. Despite an initial target of achieving 5% blending across 10 States and Union Territories, blending remained stuck at around 1.5% until 2014 due to production constraints. The fundamental shift came with the launch of the National Policy on Biofuels in May 2018, which created a whole-of-government mission involving multiple ministries to expand feedstocks, build infrastructure, and encourage investment.

A landmark step came in August 2021 when Oil Marketing Companies (IOCL, BPCL, HPCL) issued Expressions of Interest for establishing Dedicated Ethanol Plants (DEPs) in ethanol-deficit regions. These projects offered assured long-term purchase agreements, tripartite financing arrangements with public sector banks, and mandatory supply for the Ethanol Blended Petrol Programme. The progression to E20 was deliberate and staggered: ESY 2020-21 achieved ~8.1% blending, ESY 2021-22 reached 10.0%, ESY 2022-23 reached 12.1%, ESY 2023-24 reached 14.60%, ESY 2024-25 reached 19.20%, and ESY 2025-26 (Nov-June 2026) achieved the 20% target.

Economic and Strategic Benefits

The programme has delivered substantial economic benefits. Since ESY 2014-15, it has saved over ₹1.97 lakh crore in foreign exchange, substituted nearly 316 lakh metric tonnes of crude oil, reduced around 952 lakh metric tonnes of CO₂ emissions, and transferred more than ₹1.66 lakh crore directly to Indian farmers. The government purchases ethanol at remunerative prices to ensure fair compensation for farmers. The procurement price for ethanol has risen steadily across feedstocks: C-Molasses increased from ₹46.66/litre in ESY 2021-22 to ₹57.97/litre in ESY 2025-26; B-Molasses is at ₹60.73/litre; Sugarcane Juice/Sugar/Syrup is at ₹65.61/litre; Damaged Food Grains are at ₹64.00/litre; FCI Rice increased from ₹56.87/litre to ₹60.32/litre; and Maize increased significantly from ₹52.92/litre to ₹71.86/litre (including an incentive of ₹5.79).

This domestic procurement insulates consumers from global crude oil volatility. Nearly 20% of every litre of petrol sold is domestically produced ethanol, procured at a stable price. This has resulted in India witnessing one of the most moderated increases in retail fuel prices globally. Data shows that between June 2022 and June 2026, petrol prices in Delhi rose only 5.58% (from ₹96.72 to ₹102.12), compared to increases of 39.77% in Pakistan, 36.66% in Sri Lanka, and over 18% in European nations like Italy and Germany.

Vehicle Compatibility and Technical Validation

The document strongly counters concerns that E20 damages older vehicles. Before finalizing the roadmap, the Government constituted expert committees involving automobile manufacturers, the Automotive Research Association of India (ARAI), the Society of Indian Automobile Manufacturers (SIAM), oil companies, and technical institutions. E20 underwent over 40,000 kilometres of scientific testing followed by extensive field validation. Real-world evidence is cited: 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. The government asserts that vehicle manuals stating "E10 compatible" reflect the fuel specification at the time of homologation and do not imply incompatibility with newer, scientifically validated fuels like E20.

Future Roadmap and Global Leadership

India's ethanol production capacity has scaled to nearly 20 billion litres, well above the approximately 11 billion litres required to sustain the E20 mandate. The government is now examining goals beyond the 20% target, with a phased move towards E25, E27, and E30. On World Environment Day (5 June 2026), the Minister led the launch event for E85 flex-fuel promotion, positioning flex-fuel vehicles alongside EVs in India's low-carbon mobility mix. India has also taken a global leadership role by launching the Global Biofuels Alliance (GBA) on 9 September 2023 on the sidelines of the G20 Summit in New Delhi to foster international cooperation on sustainable biofuels.
