Organizational Framework

For important sustainability–related matters, our system consists of discussions at the business execution line, e.g., the Sustainability Promotion Committee and Executive Management Committee, and supervision by the Board of Directors and Risk Committee. Constructive discussions are held with outside directors who have experience and expertise in sustainability, as well as with external experts in attendance at Risk Committee and Sustainability Promotion Committee meetings. The resulting feedback is used in establishing policy and promoting our initiatives.

In fiscal 2021, we aimed to strengthen our framework by establishing the Sustainability Promotion Committee, and by forming and expanding specialist departments for promoting sustainable business. Moreover, based on thorough discussions by our business execution and supervisory lines and with attention to both opportunity and risk, we strengthened initiatives related to climate change responses, respect for human rights, environmentally and socially responsible financing and investment activity, and sustainable business.

In addition, in September 2022, we established the new position of Group Chief Sustainability Officer (Group CSuO) to promote sustainability initiatives throughout the Mizuho group. The Group CSuO will not be affiliated with any specific in–house company, unit, or group, but rather report directly to the Group CEO, and will plan and promote sustainability initiatives for the entire Mizuho group. Further, under the Group Chief Risk Officer (Group CRO), we strengthen our system for conducting centralized sustainability-related risk management.
