Topic:GS-3: Energy Security | Biofuels | Environment | Agriculture , GS-2: Governance | Policy Implementation | International Cooperation
Context
- India has achieved the target of 20% ethanol blending (E20) in petrol during Ethanol Supply Year (ESY) 2025–26, five years ahead of the original 2030 target under the National Policy on Biofuels, 2018.
- From April 2026, E20 petrol (minimum RON 95) has become the standard petrol supplied across the country.
Key Data at a Glance
- Ethanol blending: <1.5% (ESY 2013–14) → 20% (ESY 2025–26)
- Target achieved: 5 years ahead of schedule
- Ethanol procurement: 38 crore litres → 1,200+ crore litres
- Production capacity: 421 crore litres (2014) → ~2,000 crore litres (2026)
- Foreign exchange saved: ₹1.97 lakh crore
- Farmer payments: ₹1.66 lakh crore
- CO₂ emissions reduced: 952 lakh MT
- Crude oil substituted: 316 lakh MT
- Minimum fuel standard: RON 95 for E20 petrol
Issue in Brief
- The Ethanol Blended Petrol (EBP) Programme has transformed India from a low-blending country into one of the world’s leading ethanol economies.
- The programme aims to improve energy security, reduce crude oil imports, enhance farmer income and lower greenhouse gas emissions.
Static Background
What is Ethanol?
- Ethanol (C₂H₅OH) is a renewable biofuel produced mainly through fermentation of sugar- and starch-based feedstocks.
- Major feedstocks:
- Sugarcane juice
- B-heavy molasses
- Sugar syrup
- Maize
- Surplus rice
- Damaged food grains
- Agricultural residues (2G ethanol)
Blending Levels
- E10 = 10% Ethanol + 90% Petrol
- E20 = 20% Ethanol + 80% Petrol
- E85/E100 require Flex Fuel Vehicles (FFVs).
Evolution of India’s EBP Programme
- 2001: Pilot programme launched.
- 2004–06: E5 introduced in selected states.
- 2013: Gazette notification for nationwide expansion.
- 2018:
- National Policy on Biofuels notified.
- Feedstocks diversified beyond sugarcane.
- GST reduced to 5%.
- Interest Subvention Scheme introduced.
- 2021:
- NITI Aayog released Ethanol Blending Roadmap.
- 2022:
- E10 achieved ahead of schedule.
- 2023:
- PM launched E20 fuel.
- India launched the Global Biofuels Alliance during the G20 Summit.
- 2025–26:
- E20 target achieved.
- April 2026:
- Nationwide E20 mandate implemented.

Critical Analysis
Strengths
- Significant reduction in oil import dependence.
- Simultaneous gains in farmer income and environmental sustainability.
- Strong inter-ministerial coordination.
- Diversified feedstock base after 2018 reforms.
- India emerging as a global leader through the Global Biofuels Alliance.
Limitations
- Food-versus-fuel concerns with maize and rice diversion.
- Sugarcane remains highly water intensive.
- Commercial viability of second-generation ethanol is still limited.
- Consumers currently have no alternative to E20 petrol.
- Maintaining quality standards across the supply chain remains challenging.
Way Forward
- Accelerate commercial deployment of second-generation ethanol plants.
- Promote water-efficient feedstocks such as maize and agricultural residues.
- Strengthen BIS-based quality monitoring through digital surveillance.
- Develop a comprehensive national policy for Flex Fuel Vehicles.
- Publish independent data on mileage, emissions and vehicle performance.
- Announce a phased roadmap for E25 and E30 after stakeholder consultation.
- Expand biofuel use into aviation, heavy transport and industrial sectors.
