Collaboration to Make Engine-Equipped Vehicles Carbon Neutral Using Synthetic Fuel

Press Release: ENEOS Corporation (hereinafter “ENEOS”), Suzuki Motor Corporation (hereinafter “Suzuki”), Subaru Corporation (hereinafter “Subaru”), DAIHATSU MOTOR CO., LTD. (hereinafter “Daihatsu”), Toyota Motor Corporation (hereinafter “Toyota”), and Mazda Motor Corporation (hereinafter “Mazda”) are pleased to announce they will provide passenger vehicles that use a fuel mixture containing synthetic fuel during the Expo 2025 Osaka, Kansai, Japan (hereinafter “the Expo”) event period^*1 for transporting guests and related parties within the venue.

With support^*2 from the Green Innovation Fund of the New Energy and Industrial Technology Development Organization (NEDO), ENEOS will provide synthetic fuel produced at a demonstration plant^*3 completed in September 2024 within its Central Technical Research Laboratory. This fuel will be supplied to vehicles for transporting guests provided by Toyota and Mazda, as well as vehicles for transporting related parties provided by Suzuki, Subaru, and Daihatsu. The synthetic fuel to be used has been confirmed in advance by Suzuki, Subaru, Daihatsu, Toyota, and Mazda to be able to operate similarly to gasoline.

Synthetic fuels are clean energy sources made from hydrogen derived from renewable energy sources and CO₂ that can reduce CO₂ emissions throughout their product lifecycle. As liquid fuels, they can utilize existing infrastructure and therefore contribute to reducing internal combustion engine CO₂ emissions.

By operating the vehicles for transporting guests and related parties at the Expo, ENEOS, Suzuki, SUBARU, Daihatsu, Toyota, and Mazda will promote the idea that engine-equipped vehicles running on synthetic fuel are a key mobility option on the path toward carbon neutrality. In addition, it will contribute to achieving the Expo’s sustainability mission as laid out in the EXPO 2025 Green Vision^*4 .
