Marubeni official website. This page offers you information about our Environmental Management.
In full awareness of its responsibilities as a good corporate citizen, recognizing the environmental problems as material issues, the Marubeni Group will make every effort to simultaneously pursue both a prosperous society and environmental conservation, while aiming to achieve the sustainable development of society.
As a global corporate entity that engages in diverse business activities across a broad range of sectors, the Marubeni Group will apply the Environmental Management System to all the activities, services and products of the Marubeni Group, and observe the following principles it has established for environmental conservation.
The Marubeni Group pursues the five objectives below in accordance with the Marubeni Group Environmental Policy in order to help to protect the environment and to reduce the environmental impact caused by its business activities.
The Marubeni Group understands the importance of reducing the impact on the environment and surrounding communities when closing down mines. We use a local business entity to communicate with local communities and other stakeholders from the project planning stage, formulate a mine closure plan, conduct an environmental impact assessment, obtain environment-related authorizations from regulatory agencies, carry out various types of monitoring necessary for maintaining those authorizations, and strive to minimize the social and environmental impact when the mine is decommissioned. We also start the necessary rehabilitation before mine closure to lessen the environmental impact after the mine closes.
At the beginning of each fiscal year, Marubeni uses an Environmental Plan / Check Sheet to identify the issues specific to each Business Division regarding environmental risk management, Group company administration, promotion of environmental business, conservation of energy and resources, prevention of pollution, and other such matters. Marubeni then establishes environmental targets for each Business Division and works towards achieving them.
The Marubeni Group Environmental Policy was established in 1998 as the embodiment of the Marubeni Group’s firm commitment to environmental conservation.The Marubeni Group promotes environmental considerations in its own business operations under the leadership of the Environment Committee chaired by the Chief Sustainability Officer, who is Director, Member of the Board, and Representative Executive Officer.
The environmental management system (EMS) based on ISO 14001 is to promote continuous improvement through planning, implementation, operation, inspection, and management review of our environmental initiatives, using the PDCA cycle. Marubeni (Tokyo Head Office, Hokkaido Branch, Chubu Branch, Osaka Branch, Kyushu Branch, and Kawasaki Clean-Power) has introduced ISO 14001 environmental management system (EMS) as a tool to assist all employees in addressing environmental issues based on a common understanding. Based on the survey for FYE 3/2026 (as of October 2025), the status of Marubeni Group’s acquisition of environmental management systems based on ISO 14001 is as follows:
The Marubeni Group in Marubeni Group Environmental Policy includes Marubeni Corporation and the subsidiaries listed below:
Each Business Division at Marubeni formulates environmental targets and action plans at the beginning of each fiscal year and self-checks its progress against the plan in September and February using the Environmental Plan/Check Sheet.
Our performance for ISO 14001 is subject to audits every year by LRQA Limited. Marubeni has continuously been certified in FYE 3/2026. We undergo ISO certificate renewal once every three years and periodic surveillance audits in the other two years.
Internal environmental audits are conducted every year based on ISO 14001. In FYE 3/2026, audits were conducted on all Business Divisions, General Affairs Dept. (Current: Human Resources & General Affairs Department), and four branches (Osaka, Chubu, Hokkaido, and Kyushu). The Stakeholder Engagement Department formed an internal audit team, and personnel who had an internal auditor qualification verified whether the Company’s environmental management system was properly operated through interviews and other appropriate means with personnel in each Business Divisions, department, or branch. In addition to legal compliance with environment-related laws and regulations, we strive to prevent environmental risks by multifaceted analysis on various aspects, such as the management at the point of change in each business.
Each department at Marubeni and subsidiaries list applicable environmental laws, regulations, standards, and rules, and perform periodic reviews to ensure compliance with the regulatory requirements. During FYE 3/2026, Marubeni conducted an assessment to determine whether its 77 departments and 126 Marubeni Group companies were in compliance with the Waste Management and Public Cleansing Act. Marubeni also conducted an e-learning training program on the Waste Management and Public Cleansing Act for all domestic employees, including temporary employees. At the same time, training programs were held on the same topic at the Tokyo Head Office and major domestic branches (Osaka, Chubu, Hokkaido, and Kyushu), where external experts provided pertinent guidelines and information. A total of 884 people, including those from Marubeni Group companies, participated in the training programs.As a result of these and other initiatives, Marubeni had no serious incidents involving violations of environmental laws or regulations in FYE 3/2026.
Marubeni provides environmental education to its employees to help raise their awareness of relevant issues. In FYE 3/2026, Marubeni organized the Environmental Representatives e-learning Training Program and the ISO 14001 Internal Environmental Auditors Training Program, in addition to training for new employees that includes addressing environmental issues, such as EMS.
From FYE 3/2021, we introduced a sustainability assessment tool to identify and assess different kinds of sustainability risks, not only environmental risks but also social risks such as occupational health and safety and human rights.
