Kotaro Chiba and associates, the joint-owners of the HondaJet Elite used in this flight,
endorse Euglena’s “GREEN OIL JAPAN” philosophy and this has led to their use of Euglena’s
SUSTEO biofuel as a means to reduce the amount of CO2emissions when traveling by jetaircraft. This is the first time in the world that the SUSTEO jet fuel has been used in acommercial aircraft.
SUSTEO used in this flight is a biofuel created with a blendstock of existing petroleumbased jet fuel and renewable jet fuel manufactured using the BIC process at Euglena’s biofuel
manufacturing demonstration plant, and has passed compliance testing for ASTM D7566
Annex 6 standards conducted by an external inspection agency*2. Lipids derived from usedcooking oil and microalgae Euglena are used for the raw material to create this renewable jetfuel.

Technology Development Organization (NEDO), selected Euglena’s renewable jet fuelproduction technology development project, which involves the development of microalgaebased technology and the building of a supply chain model through demonstration, as apublic-offering model project*3. In response to this, Euglena has been promoting
technological development in the production of microalgae as a raw material for fuel as well
as developing a complete supply chain from raw material procurement to fuel manufacturing
technology and the supply of fuel, with the intent of operating a biofuel manufacturingcommercial plant by 2025.
