Hiroshima and Tokyo, Japan, June 3, 2026 - (JCN Newswire) - Mazda Motor Corporation (Mazda) and Nippon Express Co., Ltd., a group company of NIPPON EXPRESS HOLDINGS, INC., have launched a demonstration trial using biodiesel fuel (HVO*1) for finished vehicle transport trailers, starting in May 2026.

Mazda is aiming to achieve carbon neutrality (CN) across its entire supply chain by 2050, while the NX Group is working toward the realization of a carbon-neutral society by 2050 and contributing to environmental conservation. Through this demonstration trial, the two companies seek to explore the potential contribution to decarbonization in the logistics for finished vehicles and parts, while also promoting the social implementation of alternative fuels.

This demonstration trial is conducted between Hofu’s Nishinoura district plant and Nakanoseki finished vehicle yard (approximately 12 km round trip) through the end of fiscal year 2026. It will evaluate fuel efficiency, performance, and operational challenges, while accumulating insights for future expansion. The biodiesel fuel will be procured by NX Shoji Co., Ltd., and the two trailers used in the demonstration trial will be operated under conditions equivalent to those of conventional diesel fuel, including maintenance and inspection practices, with the cooperation of Isuzu Motors Limited.

Going forward, in addition to logistics companies and vehicle manufacturers, Mazda will collaborate with fuel suppliers and regionally rooted businesses to expand demand, enhance supply systems and infrastructure, and build a sustainable environment for the long-term use of HVO.

Leveraging our expertise in finished vehicle logistics, we will carefully evaluate the impact of fuel switching on transport quality and operations, and contribute to the realization of sustainable logistics and decarbonization of the entire supply chain.

Building on this demonstration trial, the two companies will expand the circle of like-minded partners and advance decarbonization across the supply chain.
