The Japanese government plans to require oil wholesalers to make sustainable aviation fuel, or SAF, account for at least 10 percent of their supply to domestic airports in 2030.
A council formed by government officials, oil refiners and major airlines adopted the proposal on Friday.
SAF is made from biomass or waste oil. Its output of carbon dioxide is up to 80 percent less than conventional jet fuels.
The government has already targeted increasing the ratio of SAF used at all airports to 10 percent by the end of the decade. The regulations on oil wholesalers are a way to help achieve the goal.
Global production of SAF is limited at this time. The government plans to step up support for domestic companies willing to invest in equipment to secure a stable supply.
