Materiality of MHI Group

To enhance corporate value and grow in the medium to long term through solutions to social issues, in fiscal 2020, MHI Group has identified materiality it should be addressing.

In response to the increasing importance of sustainability in international standards and guidelines, as seen in recent years in the Sustainable Development Goals (SDGs) adopted by the United Nations, growing ESG Investment, and the EU taxonomy and subsequent changes in megatrends influencing the MHI Group, in 2020 we reviewed the materiality identified in 2015 and added five new items as noted below. In fiscal 2022 we set progress monitoring indicators (KPIs) for each materiality category (see below). Going forward, we will manage progress using the KPIs and implement a PDCA cycle.
Activities relating to materiality embody our sustainability management from the business aspect. To make them effective, we have appointed individuals in charge of each materiality category and created a subcommittee to oversee this work. We considered specific measures and a roadmap. In October 2021, we established the Materiality Council, chaired by the President, to follow up on business activities aimed at realizing materiality goals and to instruct business divisions to take necessary measures. These activities are important themes in sustainability management and are regularly reported to the Board of Directors.

Processes Defining Materiality

In redefining materiality, we first took an inventory of the Group’s businesses, then linked them to a list of social issues prioritized in line with international frameworks, including the SDGs, the Global Reporting Initiatives (GRI) Standards, ISO 26000, the SASB Standards, and the EU taxonomy.
We then mapped the issues with consideration both to their level of impact on society and from the viewpoint of their importance to the Company.
Additionally, a series of reviews were conducted, primarily by the CSR Committee, and opinions obtained through dialogue with outside experts were also reflected in the selection, which was finalized upon approval of the Executive Committee and the Board of Directors.
Going forward, we will promote sustainability management by promoting activities in cooperation with business divisions and related divisions centered on the responsible managers and supervising divisions, monitoring progress on the Materiality Council and implementing PDCA.

Discussion of the Materiality Determination with Outside Directors

Step 5 of the materiality determination process involves setting company-wide objectives and selecting KPIs for monitoring progress. This step was performed mainly by a task force comprising young and mid-level employees who will shoulder MHI Group’s future. In May 2021, the task force met with outside directors and discussed the objectives and metrics, and had wanting the activity of materiality to develop than an outside director more, a powerful yell.
