Cosmo Oil Marketing Co., Ltd. (hereafter, "the Company"), a subsidiary of Cosmo Energy Holdings Co., Ltd., and Chita Driving School LLC (hereafter, "Chita Driving School"), a member of the Meitetsu Group, announced that they officially began supplying domestically produced biodiesel fuel, "Cosmo CF-51"—which meets the national standards for diesel fuel—for training trucks and other vehicles used at Chita Driving School from February 17, following trial runs.
Cosmo CF-5 is refined and produced from, in part, used cooking oil2 collected from the Meitetsu Group. By adopting Cosmo CF-5 as fuel for its training vehicles, Chita Driving School will contribute to boosting the value of circular communities.

Notably, the use of biofuel in training vehicles marks the first such initiative in Aichi Prefecture3.
