In March 2023, Japan updated its transport biofuel standards. Japan will maintain annual target volume of on-road bioethanol at 824 million liters till March 2028. Boosting domestic production of sustainable aviation fuel (SAF), including alcohol-to-jet (ATJ) SAF, is Japan’s primary focus to expand biofuel consumption. Japan is planning to develop a separate SAF target volume by the time SAF becomes commercially available.
