Sinanen Oil Square Tsurumi■ Beginning with Sinanen Oil Square Tsurumi, Susteo to be sold in the Kanto region, thenacross all of Japan
Sinanen operates petroleum supply facilities, called oil squares and kerosene centers, which serve
as key regional infrastructure across Japan. Now, Sinanen Oil Square Tsurumi in Yokohama City,
Kanagawa has begun to handle Susteo in addition to its existing fuels as part of a new businessinitiative to contribute to the realization of a decarbonized society.
Biodiesel fuels like Susteo are alternative fuels to diesel that reduce CO2 emissions. These are mainly
used for vehicles such as commercial trucks and buses, as well as construction machinery. Use ofSusteo instead of traditional diesel cuts CO2 emissions from fuel combustion by about 20%*1, assistingin the movement toward carbon neutrality.

PRESS RELEASE■ Partnership structure
In providing Susteo to customers, Sinanen will utilize its own petroleum depots as sales bases, while
Hirano Sekiyu will be responsible for transportation to customers, creating a one-stop system.

■ Future outlook
In the future, Susteo is to be offered at oil squares and kerosene centers in the Kanto region, andthen gradually to the rest of the country.
In addition, Sinanen subsidiary and petroleum product transporter Synergy Transport Co., Ltd.
(Headquarters: Sapporo City, Hokkaido, Representative Director and President: Kazunori Nemoto)plans to start using Susteo in its own delivery vehicles by the end of this fiscal year. Sinanen willcontribute to further decarbonization by using Susteo not only at oil squares but also in its own fleetof delivery vehicles.

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 ofabsorb 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*2 fuel with properties equivalent to those of fossil fuel-derived diesel fuel,allowing it to be used without adjustment in existing vehicles.

PRESS RELEASE*1 The Susteo provided in this initiative is a mixture of 20% biofuel and 80% petroleum diesel.
*2 A generic term for a molecule composed only of carbon and hydrogen, and is the main componentof products such as petroleum and natural gas.
