Yanmar Group Green Procurement Guidelines

Yanmar Logo

January 2023 (8th Edition)


Environmentally-aware conscious corporations are calling the 21st century the “Century of the Environment” because civilization cannot grow without harmonizing with the natural world. Businesses are strongly urged to point their business activities in a direction which will lead to the formation of a “recycling-oriented socio-economic system”.

Yanmar Group, in full recognition that it handles products which can impose environmental load, undertakes to contribute to the growth of a sustainable society as a pioneer in energy technology. We have Yanmar’s Global Environmental Charter, and environmental considerations are also shown in our business activities. Our group action policy is:

  • “We implement Group-wide environment management”,
  • “We establish voluntary environmental regulations in order to achieve superior levels of environmental conservation”,
  • “We promote environmental conservation throughout Yanmar Group”,
  • “We actively share information about environmental conservation both internally and externally” and
  • We promote effective measures for environmental management systematically and on a continuous basis”.

We also have established a code for suppliers, under the basic procurement policy.

In accordance with these policies, our products are made with parts and materials provided by many suppliers. In view of that, our efforts alone do not suffice towards reducing environmental load, such as the impact of environmentally hazardous substances on people and the environment, and the impact of greenhouse gases (GHG) across all stages of production. It is absolutely essential that our suppliers from whom we purchase items, parts and materials also cooperate in our environmental efforts.

Based on this belief and foundation, this Guideline summaries our green procurement standards for our suppliers and our request for the suppliers’ cooperation to further enhance our environmental performance.
This is the eighth edition of our “Green Procurement Guidelines”.
We ask for your continued cooperation in connection with this important subject.
