In a pivotal move for the aviation sector, the Indian government officially authorized the blending of ethanol and synthetic hydrocarbons into Aviation Turbine Fuel (ATF) on Wednesday, April 22, 2026.
This policy shift, enacted via an amendment to the Aviation Turbine Fuel (Regulation of Marketing) Order, 2001, aims to accelerate India’s transition toward Sustainable Aviation Fuel (SAF) and reduce its 87% dependence on imported crude oil.
1. Redefining Jet Fuel
The Ministry of Petroleum and Natural Gas (MoPNG) has fundamentally broadened the legal definition of ATF to move beyond traditional fossil-based standards.
- New Standards: ATF is now defined as a mixture of hydrocarbons conforming to IS 1571, or blends incorporating synthetic hydrocarbons compliant with the newer IS 17081 standards.
- Broad Scope: The amendment allows for “man-made” hydrocarbons derived from renewable feedstocks, including agricultural residues, waste oils, sugars, and even captured CO2.
- Engine Compatibility: This is categorized as “drop-in” fuel, meaning it is chemically similar to traditional jet fuel and can be used in existing aircraft engines without major modifications.
2. Mandatory vs. Voluntary Targets
While the legal framework for blending is now in place, the government has refrained from imposing immediate mandatory targets for domestic flights. Instead, it has set a phased roadmap aligned with global CORSIA (Carbon Offsetting and Reduction Scheme for International Aviation) standards.
| Year | Blending Target (International Flights) | Status |
| 2026 | 0% (Legal Infrastructure Ready) | Voluntary |
| 2027 | 1% SAF | Mandatory (CORSIA) |
| 2028 | 2% SAF | Mandatory (CORSIA) |
| 2030 | 5% SAF | Mandatory (CORSIA) |
3. The “Alcohol-to-Jet” (AtJ) Opportunity
A government-commissioned feasibility study presented to the ICAO in late 2025 identified the Alcohol-to-Jet (AtJ) pathway as India’s single greatest opportunity for SAF production.
- Ethanol Surplus: With India already achieving E20 (20% ethanol) in road transport this month, the aviation sector is being prioritized as the next major consumer of India’s sugarcane and grain-based ethanol surplus.
- IATA Recommendation: The International Air Transport Association (IATA) has urged the Indian government to prioritize ethanol for aviation over road transport, arguing that cars have alternatives like electrification, whereas aviation currently does not.
4. Economic and Geopolitical Drivers
The timing of this announcement is heavily influenced by the ongoing energy security crisis:
- West Asia Conflict: The US-imposed blockade on the Strait of Hormuz and strikes on Iranian infrastructure have made diversifying away from crude oil an urgent national security priority.
- Cost Factor: SAF is currently 3 to 5 times more expensive than conventional jet fuel. To bridge this gap, the government is reportedly considering production subsidies and tax incentives to prevent a sharp spike in airfares.
- Self-Reliance: Union Minister Nitin Gadkari recently stated that India should eventually “aspire to achieve 100% ethanol blending” across all transport sectors to eliminate foreign fuel dependence.
