Environmental Management


MC considers addressing sustainability challenges as one of its most important management issues. We have therefore been actively engaged in promoting a range of initiatives towards preserving the global environment through every aspect of our business. The cornerstone of these activities is our Environmental Charter, which was established in 1996. The charter clearly outlines our fundamental stance regarding environmental issues to all of our stakeholders. Based on this charter, MC conducts a variety of activities and strives to create and increase environmental value. The charter has been revised as necessary in order to reflect the fact that environmental issues and awareness are constantly evolving.
MC has established environmental management systems (EMS) that are compliant with ISO 14001, with the President & CEO serving as the chief officer in charge of EMS. In keeping with the spirit of the Environmental Charter, MC is advancing EMS activities based on its Environmental Policy.
Specifically, by having the President & CEO manage the targets set the previous fiscal year for both business and office activities, determine policies for the next year and establish systems for internal deployment, we are striving to continuously enhance and improve our EMS in harmony with our business activities. We will continue to seek out truly effective initiatives that contribute to our company’s sustainable growth.

Activity Plans and Targets

Under its environmental management systems (EMS), MC sets targets for both business activities and office activities, and works to reduce its environmental impact in each of these areas.

Business Activities

The MC Group has set a target to reduce its greenhouse gas (GHG) emissions per total assets by 25% by 2030 compared to year ended March 2017 levels. Initiatives with target subsidiaries to reduce emissions accordingly were also initiated.

Office Activities

MC is working to minimize the environmental impact of its office operations on a non-consolidated basis through reductions in electricity consumption, paper consumption, and waste production.

Reductions of Electricity and Paper Consumption
At its Head Offices, MC targets a reduction of 1% compared to the previous fiscal year. Individual targets and reduction measures are implemented at each branch and other offices in Japan. Although the impact of COVID-19 meant that it was not possible to set quantitative targets for the fiscal year ended March 2021, we made efforts to accurately measure our performance and implement reductions by extending telecommuting, achieving significant reductions.
Reduction of Waste Production
MC aims to reduce waste production at its Head Offices by 1% compared to the previous fiscal year in principle, and will revise this target based on conditions of the previous fiscal year.
Although the impact of COVID-19 meant that it was not possible to set quantitative targets for the fiscal year ended March 2021, we made efforts to accurately measure our performance and implement reductions by extending telecommuting, achieving significant reductions. Numerical targets are not set for branches and other offices in Japan due to their status as tenants, and thus waste reduction and sorting for disposal are carried out according to the requirements of each building.

Environmental Audits

MC conducts internal environmental audits every year in accordance with ISO 14001. Audits are conducted by forming audit teams comprised of members of the Corporate Sustainability Dept. The audit teams confirm whether EMS is being effectively implemented in each business group. The audit teams report their findings to the President & CEO, who serves as the chief officer in charge of EMS.

Environmental Communications

When MC is requested by customers or other external stakeholders to provide environmental information, MC discloses this information by following the processes stipulated by the ISO 14001 standards. This information includes questionnaire responses and certified copies of documentation associated with the ISO certification process. In the fiscal year ended March 2020, MC responded to 32 questionnaires and provided 12 certified copies of its ISO documentation.

Furthermore, in the fiscal year ended March 2020, MC held seminars on topics including the ISO 14001 standards. When compliance with revised environmental laws and regulations requires new measures, MC holds seminars to disseminate the information throughout MC.

Procurement of CO2-free electricity for the Head Office Building

As part of efforts to contribute to ”Transitioning to a Low-carbon Society”, one of MC’s Key Sustainability Issues, MC has switched to green power for the electricity procured for its Head Office building (the Mitsubishi Shoji Building). CO2-free electricity with environmental value (tracked non-Fossil Fuel Energy Certificates*1) is generated at a solar power plant invested in and operated by Mitsubishi Corporation Energy Solutions Ltd., which is engaged in the power generation business, and procured through MC Retail Energy Co., Ltd., which is engaged in the power retailing business. As such, electricity demand in the Mitsubishi Shoji Building is covered by renewable energy sources that also meet the requirements of RE100*2. From power generation to retail, MC Group companies work together to supply, procure and use renewable energy, creating environmental value by leveraging the MC Group’s comprehensive capabilities in the power value chain.


  1. *1 Non-Fossil Fuel Energy Certificates certify the environmental value of electricity as being generated from non-fossil fuel energy sources, such as renewable energy sources, under the Act on the Promotion of Use of Non-fossil Energy Sources and Effective Use of Fossil Energy Materials by Energy Suppliers.
  2. *2 An international initiative that aims for 100% of the energy used in business operations to be procured from renewable sources.

Relevant Data

Number of Environmental Reports and Corrective Measures

In the implementation of EMS, a system has been established for reporting and correcting matters relating to infringements of laws and ordinances as well as guidance from authorities. The incidents are shared throughout MC and measures are taken to prevent recurrences.

Number of Environmental Reports and Corrective Measures
  2019.3 2020.3 2021.3
Number of reports 1 0 2
Number of corrective measures 1 0 2
(Including matters resulting in fines, penalties, etc.) 0 0 0

A reporting system which uses a compliance hotline has been instituted to appropriately respond to accidents and disasters when they occur and to promptly implement measures to prevent recurrence. The system covers not only MC but group companies as well. Going forward, MC will continue to promote EMS as well as measures to address environmental contamination such as oil pollution. Concurrently, in the event of an environmental incident, MC will promptly report the incident to the relevant parties and investigate the causes, along with considering appropriate remedial measures and preventive measures. In doing so, MC will rigorously implement measures to prevent a recurrence of the incident.
