Involvement of Management in the Creation of the Sustainability Site

The Sustainability site features information about our Group's materiality, human rights, procurement, and environmental policies, as well as about Group initiatives pertaining to sustainability, ESG goals, such as decarbonization, and progress reports on all initiatives. These matters are discussed and resolved within the Group Sustainability Committee, which is chaired by the President and CEO, and all resolutions are reported to the Board of Directors.
The remaining content featured on the Sustainability site is primarily developed by our Sustainability Promotion Department.
We conduct meetings with PR and IR personnel and external advisors whenever needed, then engage in discussions on planning, structure, and content. The materials are created after a careful examination of the content.
The content to be included must be approved by the Sustainability Promotion Officer.
