Leif rating: Likely Fair

Headquartered in Japan

Yamaha Corp. is a large diversified corporation with published environmental and labor commitments, particularly through its supplier code of conduct and human rights policy prohibiting child and forced labor. The company has committed to net-zero emissions by 2050 with specific interim targets to reduce Scope 1, 2, and 3 emissions, and appears on the CDP Climate Change A List. However, product-level material transparency is limited, and the company lacks major third-party sustainability certifications such as B Corp or Fair Trade.
