On June 10, 2025, Japan’s Ministry of Economy, Trade and Industry (METI) introduced an action plan to introduce E10 and E20 gasoline. As part of this plan, Japan aims to introduce a nationwide E10 gasoline option by 2030. To prepare for this transition, METI plans to conduct a smaller-scale introduction of E10 gasoline in 2028. Additionally, METI has proposed a revised gasoline base-line greenhouse gas (GHG) emission value for gasoline and is planning to incorporate GHG default values for ethanol derived from Brazilian corn, Thai sugarcane, and Thai cassava.
