In April 2025, I was appointed as Chief Strategy Officer (CSO), and Sustainability is one of my key responsibilities. The Sustainability Committee is responsible for planning, drafting, and proposing basic management policies, business activities, and corporate policies relating to sustainability. This aligns with our core mission of creating new value for society through our business activities, while working towards a sustainable future for both society and the company.

As one of our key management issues, we have identified material issues crucial to the sustainable growth of the company and society. We call these material issues Mitsui’s Materiality. We have aligned each Materiality to the United Nations Sustainable Development Goals (SDGs) to guide our business activities and contribute to achieving the 17 SDGs. Furthermore, we have formulated Materiality Action Plans which connect each Materiality to specific policies and initiatives to be implemented by organizations within Mitsui, and constantly monitor our progress to support the development of a sustainable society. Our Materiality was first established in 2015, was reviewed in 2019, and is currently undergoing another review, incorporating insights from our stakeholders and considering changes in the external environment.

In the Medium-Term Management Plan 2026, which ends this fiscal year, we have defined “Creating Sustainable Futures” as our future vision for integrating business and sustainability. As part of our sustainability management, we have identified climate change, natural capital, and business and human rights as key themes.
In response to climate change, we are working to achieve our goal of net-zero emissions by 2050. This includes launching renewable energy and next-generation fuel businesses, along with natural gas and LNG businesses to support the transition period. Additionally, we are contributing to the realization of a decarbonized society by restructuring our portfolio, including divesting from two coal-fired power generation projects in 2024.
Regarding natural capital, in March 2025, we endorsed the TNFD disclosure recommendations and conducted LEAP analysis based on the TNFD in three of our business fields—copper mining, seawater desalination, and crop production—where the impact and dependence on natural capital is high. We are also focusing on efforts to increase economic value through businesses that leverage natural capital.
In the area of business and human rights, we are advancing company-wide initiatives to respect human rights by providing training for both our own employees and officers as well as our suppliers, expanding the scope of human rights due diligence investigations, and strengthening our monitoring system to eliminate human rights issues.

We will continue to deepen our dialogue with diverse stakeholders, and under “Challenge and Innovation” which has been part of our DNA, we will strive to solve various social issues in the world through our business, aiming to enhance our corporate value from a long-term perspective and contribute to the realization of a sustainable society.
