Along with the growing interest in climate change, environmental and social issues, society has begun to attach greater importance to sustainability. Reflecting these trends, the Mitsubishi Materials Group established a Sustainability Policy in December 2021 (revised on April 1, 2024) to clarify the Group's attitude to promote sustainability more actively and positively. We also established a Human Rights Policy, Procurement Policy and Community Contribution Activity Policy while revising the Environmental Policy under the Sustainability Policy.
At the Mitsubishi Materials Group, based on our Corporate Philosophy “For People, Society and the Earth,” we have declared the vision of “Circulating resources for a sustainable future” and adopted the mission to “Create a sustainable future.” Based on the recognition that the sustainability of society as a whole will have a significant impact on our corporate activities in the future, we are committed to engaging in business activities that can earn the trust of stakeholders while fulfilling our social responsibilities.

The Mitsubishi Materials Group upholds its Corporate Philosophy, "For People, Society and the Earth" and is committed to earning the trust of our stakeholders by sincerely fulfilling our social responsibilities through our business activities.
We will further accelerate our proactive engagement with sustainability. The Mitsubishi Materials Group will pursue its journey for sustainable growth as we work to fulfill Our Commitment.

Stipulated on December 1, 2021
Revised on April 1, 2024

We recognize that tackling management issues regarding sustainability is essential for the Group to improve its corporate value in the medium- to long-term, and established the Sustainable Management Office on April 1, 2020 to promote centralized handling of such issues.
In promoting resource circulation, we integrated the Resource Circulation Strategy Meeting into the Strategy Council as of June 1, 2026, and have been moving forward with the examination of our resource circulation scheme at the Strategy Council from the perspective of long-term, company-wide optimization. Based on the above, we have established an organizational structure to promote and manage company-wide cross-sectoral initiatives, with the Human Resources Committee for the enhancement of human capital among material issues, and the Sustainability & SCQ Promotion Office Meeting and Strategy Council for other material issues. Their activities are reported to the Strategic Management Committee and the Board of Directors. The new organizational structure will enable us to strategically and efficiently address sustainability issues.
