Cosmo Oil Marketing Co., Ltd. (hereafter, the “Company”), a subsidiary of Cosmo Energy Holdings Co., Ltd., is pleased to announce that it has been selected to receive a subsidy under the Tokyo Metropolitan Government’s “FY2026 Domestic SAF Utilization Promotion Project” (hereafter, the “Project”) for the supply of Japan's first mass-produced domestic Sustainable Aviation Fuel (SAF) at Haneda Airport.

The Project, launched by the Tokyo Metropolitan Government in FY2025, is the first of its kind in Japan to promote the utilization of domestically produced SAF. It aims not only to decarbonize aviation fuel but also to enhance Tokyo’s global competitiveness, ensure a stable SAF supply, and support the development of the SAF market by subsidizing the price difference between domestically produced and imported SAF. Following its selection in FY2025¹, the Company was once again chosen as a subsidy recipient under the Project.

Through the Project, it is expected that the use of domestically produced SAF will be further promoted among airlines operating flights out of Haneda Airport.

The SAF subsidized under the Project was commercialized following the receipt of a New Energy and Industrial Technology Development Organization (NEDO) subsidy² in 2021, aimed at establishing a supply chain model for SAF production from domestically sourced used cooking oil. It is the first SAF to be mass produced in Japan and has obtained ISCC CORSIA and ISCC EU certifications³. These certifications are part of the International Sustainability and Carbon Certification (ISCC) initiative, which recognizes compliance with international standards for sustainable products. The fuel is produced by SAFFAIRE SKY ENERGY LLC, a joint venture formed by Cosmo Oil Co., Ltd., JGC HOLDINGS CORPORATION, and REVO International Inc., and has been supplied to airlines operating out of Haneda Airport via the Cosmo Energy Group since FY2025.

The Cosmo Energy Group has worked to establish a supply chain to deliver Japan’s first domestic SAF, with the goal of achieving net zero carbon emissions by 2050. The Group is also helping build social momentum through initiatives such as an ongoing pilot program to collect used household cooking oil at service stations for repurposing into SAF feedstock.

Recognizing decarbonization and the realization of a recycling-oriented society as key priorities, the Cosmo Energy Group remains committed to addressing societal challenges and fostering sustainable corporate development. As such, the Group will continue to promote the use of SAF in air transportation and contribute to the creation of a sustainable, resource-recycling society.
