SAF (Sustainable Aviation Fuel) is a fuel that is produced through the treatment of raw materials such as biomass, used cooking oil (UCO), and municipal solid waste (MSW). The life cycle of the fuel, from production to combustion, is much more efficient than conventional aviation fuels in terms of greenhouse gas emissions. It is an aviation fuel that can be used with existing infrastructure without modification. With the global demand for reductions in CO₂ emissions, the aviation industry is also working to reduce CO₂ emissions, mainly in overseas countries. The introduction of SAF has already begun, and there is a critical need to accelerate the development, manufacture, distribution, and use of SAF technology in Japan as well.

In this context, JGC Group established “SAFFAIRE SKY ENERGY LLC” in 2022, jointly with REVO International Inc. and Cosmo Oil Co., Ltd., with the aim of achieving the first large-scale commercial production of SAF in Japan. In December 2024, construction of a SAF production facility using used cooking oil as feedstock was completed. In March 2025, a completion ceremony for the SAF production plant was held, and in April 2025, the company commenced the production of domestically produced SAF certified as CORSIA-eligible fuel—the first of its kind in Japan. While the CO₂ reduction performance of SAF varies depending on feedstock and production technology, SAF derived from used cooking oil offers particularly high carbon reduction performance, achieving an 84% reduction in greenhouse gas (GHG) emissions compared to conventional jet fuel. Through these efforts, a comprehensive supply chain has been established, covering everything from the collection of used cooking oil as feedstock to the supply of domestically produced SAF.

Furthermore, in March 2022, JGC Group established “ACT FOR SKY,” an all-japan voluntary organization committed to realizing a carbon-neutral sky through the development of a domestic supply chain and the promotion of SAF, in collaboration with REVO International Inc., All Nippon Airways Co., Ltd., Japan Airlines Co., Ltd., and other partners. The initiative aims to drive behavioral change among both citizens and businesses by encouraging coordinated action among companies, local governments, and other stakeholders, while raising awareness of the importance of SAF, carbon neutrality, and resource circulation.

In addition, in April 2023, JGC Group launched the “Fry to Fly Project,” an initiative aimed at realizing a world where aircraft are powered by SAF derived from domestically sourced used cooking oil, in order to expand the collection of used cooking oil. In collaboration with participating organizations, various initiatives—such as event exhibitions and PR campaigns—are being carried out to promote the collection of used cooking oil and raise public awareness.
A large number of companies, local governments, and organizations are participating in this project, each undertaking unique initiatives. For further details, please visit the dedicated website below.
