Yamaha First to Use Green Aluminium in Japanese Motorcycles

Adoption of low-carbon aluminium in its drive toward carbon-neutral materials

Yamaha Motor Co., Ltd. has reached an agreement with an aluminium ingot supplier for the procurement of green aluminium.  Use of the green aluminium, which is refined using renewable energy, was included in the production of some Yamaha motorcycles from February. 

This is the first time*¹ green aluminium has been used in Japanese motorcycles, and Yamaha Motor plans to gradually expand its usage into a wider range of applications.

 “Green aluminium” is aluminium that is refined using renewable energy sources to emit less CO2 in its manufacture. Aluminium parts account for 12 to 31*² percent of the total vehicle weight of a motorcycle. Adopting green aluminium is an effective approach for reducing CO₂ emissions from the raw material manufacturing part of a product’s life cycle (falls under Scope 3 Category 1 emissions for supply chains).

Through the development of its engineering and production technologies and expertise, Yamaha Motor has actively pushed the use of recycled aluminium, which now comprises some 80*³ percent of the Company’s aluminium usage. The introduction of green aluminium is meant to complement this, and will be employed for parts that still cannot be manufactured with recycled materials. As a first step, Yamaha Motor will utilise green aluminium for certain parts in its large-displacement and off-road competition motorcycles, and the company plans to expand the number of models using the material in the future as available supply volumes allow.

In line with the Yamaha Motor Group Environmental Plan 2050, the Company is aiming to achieve carbon neutrality*⁴ throughout all of its business activities—including its entire supply chain—by 2050. To realise this, the Company has set a goal of switching to 100 percent sustainable materials by 2050, such as adopting more plant-derived resin materials, developing recyclable polypropylene, and adopting green materials and other recycled materials for its motorcycles manufactured in Japan and overseas.
