MITSUBA Group disclosed information regarding climate change in November 2023 based on the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD*1).
In order for MITSUBA Group to develop sustainably into the future, we believe that it is necessary to further promote management that incorporates a climate change perspective. Therefore, we established a TCFD Response Team under the ESG Committee, which analyzed the risks and opportunities related to climate change, and disclosed information on a four-item framework consisting of “Governance,” “Strategy,” “Risk Management,” and “Indicators and targets.”
Furthermore, we have declared our support for the TCFD recommendations and joined the TCFD Consortium (*2).
Going forward, we will continue to be aware of the business environment surrounding Mitsuba and group companies, deepen the analysis of risks and opportunities, utilize such analysis in the management strategies, and further promote measures to realize a carbon-neutral society.
*1 : TCFD refers to the Task Force on Climate-related Financial Disclosures, which was established by the Financial Stability Board at the request of the G20. The TCFD published its final report in June 2017, encouraging companies to disclose information about climate change-related risks and opportunities.
Currenty, the International Sustainability Standards Board (ISSB) has formulated the IFRS Sustainability Disclosure Standards, which incorporate the TCFD disclosure framework, and these standards are being used as the international standard for sustainability information disclosure.
*2 : The consortium was formed on May 27, 2019, to serve as a platform for discussing effective corporate information disclosure and linking this disclosed information to appropriate investment decisions by financial institutions and other organizations. The Ministry of Economy, Trade and Industry, the Financial Services Agency, and the Ministry of the Environment participate as observers.
At MITSUBA group, the ESG Committee (chaired by the Representative Director, Executive Vice President), which is a business execution committee for CSR, sets social issues that the group should particularly focus on solving as priority issues, clarifies targets, and monitors progress four times a year. The matters discussed at the ESG Committee are reported to the Management meeting twice a year, and to the Board of Directors as necessary.
Regarding risk management, MITSUBA group regularly (once a year) identifies company-wide business risks, including climate change, at the ESG Committee and evaluates them based on frequency of occurrence and various degrees of impact. Furthermore, MITSUBA has established committees under the ESG Committee to resolve issues in each area.
In response to climate change, MITSUBA has established the Carbon Neutrality Committee (Chairperson: Representative Director, President) in FY2021 to establish the Mitsuba Group Carbon Neutrality Policy, and monitorCO2 emissions per product throughout its life cycle, and strive to understand and reduce total CO2 emissions throughout the supply chain.
Regarding environmental management, the EMS committee plays a central role in implementing environmental management and environmental conservation activities. Once a year, a review is conducted by the Executive Vice president and Executive Officer, who is the general environmental manager for the entire company, confirming the effectiveness and appropriateness of initiatives, and resolutions are made at the ESG Committee for projects that have a significant impact on management.
Regarding BCM (Business Continuity Management), MITSUBA has established an appropriate management system centered on the BCP Committee to fulfill the company's product supply obligations.

The TCFD recommendations set multiple climate change scenarios, analyze the actual and potential impacts of climate-related risks and opportunities on an organization's businesses, strategies, and financial plans, and provide countermeasures for each scenario to encourage demonstrating the resilience of their strategies. Mitsuba and group companies conducted an analysis presuming two scenarios as shown in the table below. The overview of each scenario and world view, as well as reference scenarios are as follows.
| Name | 1.5℃/2℃ scenario | 4℃ scenario |
|---|---|---|
| Overview of the scenario | ・A scenario in which temperature increase is limited to 1.5 °C / 2 °C above pre-industrial levels due to an accelerated transition towards a carbon-neutral society. ・Mainly the risk of transitioning to a carbon-neutral society emerges |
・A scenario in which global warming progresses and temperatures increase by 4 °C above pre-industrial levels if no measures are taken to achieve a carbon-neutral society that exceeds the current level. ・Mainly the physical risk due to climate change |
| Overview of the world view | ・Due to changes in policies, laws, and regulations aimed at transitioning to a carbon-neutral society, such as the introduction of carbon tax and the expansion of renewable energy, the response costs and additional investments from companies will increase. ・Electrification of the automobile and motorcycle markets is progressing rapidly, and customer preferences regarding mobility are also changing. |
・The introduction of policies, laws, and regulations aimed at transitioning to a carbon-neutral society is limited. ・Electrification of the automobile and motorcycle markets progressing to a certain extent, but progress is limited. ・As climate change progresses, changes in climate patterns and the intensification and frequency of abnormal weather conditions impact operations, increasing the importance of supply chain risk management and BCP reviews. |
