India buys most of its crude oil from abroad. The Ethanol Blended Petrol (EBP) Programme cuts that dependence by mixing home-grown ethanol into ordinary petrol. It began as a small pilot two decades ago. Today, one-fifth of every litre of petrol sold in India is ethanol.
Timeline
- 2001: A pilot programme introduces 5% ethanol-blended petrol on a trial basis.
- January 2003: The EBP Programme is formally launched under the National Auto Fuel Policy. It mandates 5% blending in 9 states and 4 Union Territories.
- 2006: The 5% blending mandate is extended to more states. Blending still stays below 1.5% for years, capped by sugarcane-only supply.
- May 2018: The National Policy on Biofuels lets ethanol makers use maize and surplus foodgrains too, not just sugarcane. It targets 20% blending by 2030.
- June 2021: NITI Aayog publishes its Roadmap for Ethanol Blending in India 2020-25. Weeks later, Oil Marketing Companies invite bids for new Dedicated Ethanol Plants.
- June 2022: India hits its 10% (E10) blending target, five months early. A 2022 amendment advances the 20% target from 2030 to ESY 2025-26.
- April 2023: A phased E20 rollout begins in select cities.
- November 2025 – April 2026: India crosses 20% blending nationally. E20 becomes mandatory across all states and Union Territories from 1 April 2026.
🏛️ Must Know
EBP Programme Basics and the Road to E20
- The Ethanol Blended Petrol (EBP) Programme mixes ethanol, made from crops like sugarcane and maize, into regular petrol. It aims to cut crude oil imports, support farmer incomes, and lower emissions.
- India formally launched the EBP Programme in January 2003, under the National Auto Fuel Policy. It mandated 5% ethanol blending in 9 states and 4 Union Territories.
- India hit its 20% ethanol blending target in Ethanol Supply Year (ESY) 2025-26. This was five years ahead of the original 2030 deadline set by the National Policy on Biofuels, 2018.
- Blending was stuck below 1.5% for over a decade. It only accelerated after 2018, when reforms let ethanol makers use maize and surplus foodgrains, not just sugarcane, as feedstock.
- E20 fuel became mandatory across all Indian states and Union Territories from 1 April 2026. Petrol pumps no longer sell a separate, ethanol-free option.

Policy Timeline, Octane Science, and Global Comparison
- The National Policy on Biofuels, 2018, opened the door to grain-based ethanol. A 2022 amendment then advanced the 20% blending target from 2030 to ESY 2025-26.
- NITI Aayog published its Roadmap for Ethanol Blending in India 2020-25 in June 2021. Weeks later, in August 2021, Oil Marketing Companies invited bids for Dedicated Ethanol Plants (DEPs) in ethanol-deficit regions.
- Ethanol has a research octane number of about 108.5, well above petrol’s 84.4. Blending it into petrol at 20% raises the fuel’s effective octane rating to around 95, improving combustion in modern engines.
- India isn’t alone in this shift. Brazil mandates E27 nationwide, the world’s highest standard blend, and is raising it further. The United States runs mainly on E10, with E15 expanding. Japan uses a phased E10 blend.
- Government-cited tests found no major fuel-economy or engine-damage pattern from E20, including in older, non-E20-certified vehicles. Maruti Suzuki reported no E20-linked damage across 1.5 crore older vehicles it serviced in FY 2025-26.
- Globally, the United States is the world’s largest ethanol producer, with Brazil second. The US uses corn as its principal feedstock, while Brazil relies on sugarcane — a common point of confusion, since Brazil’s high blending mandate doesn’t mean it produces more ethanol overall.
📰 Current Affairs
Current Affairs
- On 6 August 2026, the Commerce Ministry denied media claims that India was importing large volumes of ethanol from the US, for fuel blending. It called the claims “baseless and factually incorrect.” (Source: PIB)
- The Ministry said all ethanol under the Ethanol Blended Petrol Programme comes from domestic producers. No US ethanol imports exist for fuel blending. (Source: PIB)
- It also confirmed that India-US trade talks include no concessions, or commitments, on ethanol imports for fuel blending. (Source: PIB)
- On 7 August 2026, Oil Marketing Companies (OMCs) ran nationwide tests, after media reports claimed E20 petrol had high chloride and moisture contamination. The claims were not validated. (Source: ANI)
- Reports had alleged chloride levels as high as 500 ppm. Actual samples, tested across refineries, distilleries, and depots, showed chloride at just 0-3 ppm. (Source: ANI)
- OMCs tested petrol at refineries, in over 100 samples, all at or below 1 ppm. Ethanol from 80 distilleries, and E20 from depots, also stayed below 3 ppm in over 80 samples each. (Source: ANI)
- Under an intensified drive covering over 1,000 samples, only 4 isolated instances of elevated chloride turned up. These were suspended immediately, pending root-cause analysis. (Source: ANI)
- About 90,000 retail outlets began inspecting underground storage tanks 8-12 times a day. No water ingress has been found so far. (Source: ANI)
- Separately, Maruti Suzuki reviewed 2.84 crore vehicles serviced in FY 2025-26, including over 1.5 crore older vehicles. It found no E20-related corrosion, wear, or reduced component life. (Source: ETV Bharat)
- 31 July 2026: The Petroleum Ministry rebutted claims that ethanol comes at the cost of food security. FCI rice’s share of ethanol feedstock rose from 0.02% (ESY 2023-24) to 24.64% (ESY 2025-26), paid at ₹60.32/litre — but only surplus rice, left over after all food-security needs are met. (Source: PIB)
- Over the same period, maize’s feedstock share fell from 42.6% to 35.96%. Producers simply switch between approved feedstocks, based on availability. (Source: PIB)
- Without ethanol blending, petrol would have cost around ₹125/litre when crude oil spiked to $135 a barrel. Blending held the actual price at ₹94.77/litre — nearly ₹30/litre saved. (Source: PIB)
- 23 July 2026: In a Lok Sabha reply, the Government reaffirmed E20’s safety, and clarified its blending plans. E85 fuel, at 85% ethanol, has been launched for certified Flex Fuel Vehicles — it doesn’t raise the nationwide base blend. (Source: PIB)
- About 8 crore vehicles visit fuel retail outlets every day, roughly 80% of them petrol vehicles. (Source: PIB)
- The Government has no plan to revert to E0 or E10 petrol. Running three parallel fuel grades nationwide would raise logistics costs, and complexity, substantially. (Source: PIB)
- 21 July 2026: In a Rajya Sabha reply, MoS Petroleum & Natural Gas Suresh Gopi detailed PSU OMCs’ own in-house ethanol production, alongside procurement.
- OMCs spent ₹48,757 crore (ESY 2023-24), ₹73,996 crore (ESY 2024-25), and ₹49,577 crore (ESY 2025-26, till 30 June) on ethanol procurement — over ₹1.72 lakh crore across the 3 years. 501 ethanol manufacturing units are registered as OMC suppliers.
- BPCL itself has an installed ethanol production capacity of 200 KLPD, producing 76 KL in ESY 2025-26 up to 30 June. By comparison, IOCL (228 KLPD capacity) produced 712 KL, and HPCL Biofuels (120 KLPD) produced 9,373 KL, in the same period.
- Uttar Pradesh led ethanol-blended petrol sales in ESY 2024-25, at 124.98 crore litres, followed by Maharashtra, Tamil Nadu, Karnataka, and Gujarat.

Feedstock Pricing and What Comes After E20
- This article covers the EBP Programme itself — its policy, targets, and results. For the agronomy of its two main feedstock crops, see IndEco0099 — Sugarcane Cultivation in India and IndEco0101 — Maize Cultivation in India.
- The government pays different procurement prices depending on feedstock. In ESY 2025-26, maize-based ethanol earned about ₹71.86 per litre, more than sugarcane-molasses-based ethanol at roughly ₹58-66 per litre — a deliberate incentive to diversify beyond sugarcane.
- E20 is very likely not India’s final stop. Brazil’s flex-fuel vehicles (FFVs), which run on any blend from pure petrol to pure ethanol, are being watched as a possible model for what comes after E20.
- For India’s other major biofuel and energy-transition programmes, see IndEco0118 — GOBARdhan: National Circular Bioenergy Scheme and IndEco0119 — Electric Vehicles in India. For the fossil-fuel sector ethanol is displacing, see IndEco0117 — Petroleum and Natural Gas Sector in India.
