Centre waives excise duty on 22% to 30% ethanol-blended petrol

📌 Summary:

• Centre has exempted central excise duty on petrol blends containing 22%, 25%, 27% and 30% ethanol (E22, E25, E27, E30) — nil excise rate for blends conforming to BIS standards
• First major fiscal incentive to push adoption beyond the existing E20 mandate
• Bureau of Indian Standards (BIS) notified fuel-quality specs for E22–E30 (ethanol concentration, octane, sulphur, testing, safety) effective May 15, 2026
• Objectives: cut crude oil import bill (India imports most of its crude), boost domestic biofuel use, strengthen energy security amid global supply uncertainty (West Asia conflict, Hormuz risks)
• Consumer concerns: lower mileage, possible engine wear, higher maintenance for older (pre-2023) vehicles, and lack of clarity on blend % at pumps; demand for cheaper pricing of blended fuel
• Ministry of Petroleum & Natural Gas (MoPNG) calls such concerns largely unsupported by scientific/technical evidence; admits minor fuel-economy reduction in E20
• Vehicles from 2023 onward generally E20-compatible; flex-fuel push — 5,000 flex-fuel pumps targeted by 2027-end

🎯 UPSC Relevance: GS3 Economy (government fiscal incentives, energy security, import substitution) and Environment (biofuels). Links fiscal policy, energy transition and trade balance.

📝 Prelims Facts:

• E20 = 20% ethanol + 80% petrol; new blends standardised: E22, E25, E27, E30
• BIS specifications effective May 15, 2026
• Exemption is on central excise duty; conditional on BIS conformity
• India is a net crude importer; ethanol blending part of energy-security strategy

🔑 Key Term: Ethanol Blended Petrol (EBP) Programme — blending of ethanol (mainly from sugarcane/grains) with petrol to reduce fossil-fuel imports, carbon footprint and support farmers.
