Sinanen's Logistics Subsidiary to Reduce its Annual CO2 Emissions of Approximately 566 Tons From its Fuel Transport Vehicles to Effectively Zero

- Achieved Through the Adoption of Next-Generation Biodiesel Fuel and the Use of Voluntary Credits -


Energy solutions provider Sinanen Co., Ltd. (Headquarters: Minato-ku, Tokyo, President and CEO: Naoki Shimizu), a subsidiary of Sinanen Holdings Co., Ltd. (Headquarters: Minato-ku, Tokyo, President and CEO: Masaki Yamazaki), a comprehensive energy, housing, and daily-life services provider, is pleased to announce the adoption of Susteo, a next-generation biodiesel fuel provided by Euglena Co., Ltd. (Headquarters: Minato-ku, Tokyo, Representative Director and President: Mitsuru Izumo) and the start of utilization of voluntary credits*1 for their own fuel transport vehicles operated by Sinanen's subsidiary Synergy Transport Co., Ltd. (Headquarters: Sapporo City, Hokkaido, Representative Director and President: Kazunori Nemoto), which transports petroleum products, to reduce CO2 emissions from transportation.

■Synergy Transport will reduce CO2 emissions from its own fuel transport vehicles to practically zero.
The company will supply fuel not only for its own use, but also to companies aiming to reduce CO2 emissions going forward

Efforts to reduce CO2 emissions and preserve and strengthen their absorption are accelerating in Japan in pursuit of achieving a decarbonized society with virtually zero CO2 emissions by 2050 (carbon neutrality).

In the midst of this environment, Sinanen has started handling Susteo at Sinanen Oil Square Tsurumi in Yokohama City, Kanagawa Prefecture, one of the petroleum supply facilities that support infrastructure nationwide*2, and is working on reducing CO2 emissions. To further reduce CO2 emissions, Synergy Transport has started utilizing Susteo for the fuel used in its own fuel transport vehicles from today, along with the use of voluntary credits.

This initiative enables all transport vehicles owned by Synergy Transport to transport petroleum products with virtually zero CO2 emissions, and it is expected to reduce CO2 emissions by about 566 tons annually.

Sinanen plans to provide fuels that contribute to achieving the targets, such as Susteo and fuel with carbon credits, not only for use within its Group companies but also to companies that have set CO2 emission reduction targets.

Sinanen will continue to contribute to the reduction of CO2 emissions by expanding the introduction of renewable energy toward the realization of a decarbonized society.

■About Susteo, a next-generation biodiesel fuel

Susteo is a next-generation biofuel provided by Euglena. It is made from highly sustainable biomass raw materials without hampering food supply or causing problems such as deforestation. Susteo emits CO2 at the combustion stage just like ordinary diesel fuel, but the plants and algae that it is made of absorb CO2 through photosynthesis during their growth, offering the potential to help realize carbon neutrality, a state of virtually zero CO2 emissions during fuel use. Susteo, a next-generation biodiesel fuel, is a hydrocarbon*3 fuel with properties equivalent to those of fossil fuel-derived diesel fuel, allowing it to be used without adjustment in existing vehicles.


*1. Voluntary credits are part of a mechanism for carbon offset, allowing the trading of CO2 emission reductions to offset greenhouse gas emissions that are difficult to reduce, issued by private companies, NGOs, and other organizations.
