Indian Govt Approves Ethanol Blending in Jet Fuel: What This Actually Means
.The Ministry of Petroleum and Natural Gas has issued a gazette notification permitting ethanol and other synthetic hydrocarbons to be blended into Aviation Turbine Fuel (ATF), the jet fuel used by all commercial aircraft. The change amends the Aviation Turbine Fuel (Regulation of Marketing) Order of 2001 under the Essential Commodities Act, broadening the legal definition of ATF to include blends with synthetic hydrocarbons. No mandatory blending targets for domestic flights have been set.
This matters to car and bike buyers for a specific reason: the ethanol blending push that has already changed petrol composition on the road is now expanding into a second, larger fuel category.
The same policy logic, reduce crude oil imports, support domestic ethanol production, cut carbon emissions, is driving both moves. Understanding how far this goes in aviation gives a useful read on where ground transport fuel policy may head next.
Sustainable Aviation Fuel, referred to as SAF, is the aviation equivalent of ethanol-blended petrol. It is produced from renewable feedstocks: waste cooking oils and animal fats, sugarcane and grain-based ethanol, municipal solid waste, agricultural residue, or even from captured CO2 combined with green hydrogen. The end product, when blended with standard kerosene-based jet fuel, performs functionally the same way in aircraft engines but produces fewer net carbon emissions over its full lifecycle compared to pure fossil fuel.
The terminology used in the government notification is "synthetic hydrocarbons," which is the category under which SAF sits. ATF is now formally defined as a mixture conforming to IS 1571 specifications or a blend under IS 17081 standards.
That IS 17081 standard is what governs synthetic aviation fuels. By updating the definition, the ministry has removed the regulatory barrier that previously prevented airlines or fuel suppliers from marketing blended ATF legally.
The targets are tied to CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation run by the International Civil Aviation Organisation. Under CORSIA, airlines are required to offset the CO2 from international flights that exceed 2020 emission levels. The scheme was voluntary from 2021 to 2026 and becomes mandatory for most member states from 2027 through 2035.
In line with that timeline, India has set SAF blending targets specifically for international flights: 1 percent by 2027, rising to 2 percent by 2028, and 5 percent by 2030. No equivalent targets have been established for domestic flights. Domestic aviation accounts for the majority of flight cycles in the country, and leaving it outside the mandate means the SAF requirement affects only a fraction of total jet fuel consumed here for now.
E20 petrol, which contains 20 percent ethanol, is now the standard across the country. A push toward E22 and higher blends is underway. Flex-fuel motorcycle and car platforms are being readied by manufacturers. Now aviation gets the same regulatory enabling framework, with international flights targeted first and domestic flights left open-ended.
What this tells the road transport buyer is that ethanol as a fuel additive is now firmly embedded across multiple categories, not just petrol for two-wheelers and cars. The infrastructure investment in ethanol production, which includes dedicated distilleries, storage facilities, and blending terminals, will grow with each new mandate. That deepening supply chain makes higher ethanol blends on the road more feasible and more likely, even without a formal announcement today.
