The Indonesian government plans to mandate the blending of 10% ethanol into gasoline fuel.
This was stated by the Minister of Energy and Mineral Resources (ESDM), Bahlil Lahadalia.
"Last night, we had a meeting with the President. The President has approved the plan for a mandatory 10 percent ethanol blend," Bahlil said, as reported by CNNIndonesia.com (October 7, 2025).
"Thus, we will blend our gasoline with ethanol. The purpose is to reduce our imports and to create cleaner, environmentally friendly fuel," he added.
Bahlil estimates that the mandatory blending of gasoline with ethanol in Indonesia will take effect in the next 2-3 years, or around 2027-2028.
"So, we need to calculate it carefully first," Bahlil said.
The use of ethanol as fuel has been implemented in various countries for many years.
According to data from the United States Department of Agriculture (USDA), this practice is most prevalent in the United States (US).
In 2018, the US consumed 14.4 billion gallons of ethanol for fuel or fuel blending.
Other countries that had implemented similar practices in 2018 include Brazil, China, Canada, India, Thailand, Germany, Argentina, France, Japan, and the United Kingdom, with ethanol consumption volumes as shown in the graph.
These countries have policies for blending ethanol with fuel in varying proportions.
In 2018, the US already blended its gasoline with 10% ethanol. Meanwhile, Brazil's ethanol blend proportion reached 50% at that time.
"In most fuel ethanol-consuming countries, ethanol policy typically serves two purposes: to reduce greenhouse gas and exhaust emissions under clean air policies and support the domestic agricultural industry," the USDA stated in its report, Global Demand for Fuel Ethanol Through 2030.
"In recent years, ethanol's use has also expanded as an economical blending feedstock to produce higher grades of finished gasoline," they said.
