In order to support the introduction of sustainable aviation fuel (SAF), the Ministry of Economy, Trade and Industry (METI) is going to hold expert committee meetings to discuss the framework of upcoming SAF regulations. Japan is likely to rely on ASTM D7566 as SAF definition. Japan is likely to set to reduce aviation greenhouse gas emissions by 5 percent or more through SAF by 2030. METI hopes to start drafting SAF legislation from as early as autumn 2024.
