Yamaha declared today that it had attained a deal with an aluminium ingot provider for green aluminium, making use of it as a part material in its motorcycles from February 2023. This is the inaugural utilization of green aluminium in Japanese motorcycles and Yamaha intends to progress its use in forthcoming models.

“Green aluminium” is aluminium that is refined using renewable energy sources to emit around 60% less CO2 in its manufacture compared to traditionally refined aluminium. Of course, the percentage of less emission by renewable energy depends per manufacturer. Aluminium parts account for 12% to 31% of the total vehicle weight of a motorcycle, so adopting green aluminium is one 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).

Yamaha has made advances in its engineering and production techniques, leading to 80% of their aluminium use now coming from recycled materials. To further support their green efforts, green aluminium will be employed for components that are not yet able to be manufactured using recycled materials. This material will first be utilized in large-displacement and off-road competition motorcycles, with hopes of extending its use to other models when possible.

Future Yamaha models for green aluminium

In accordance with the Yamaha Group Environmental Plan 2050, Yamaha is aiming to attain carbon neutrality across its operations and supply chain by 2050. To fulfil this, the company is striving to use only sustainable materials in their production of motorcycles in Japan and overseas by then, such as implementing more plant-derived resin materials, developing recyclable polypropylene and utilising green materials and other recycled components.
