Environmental Management System (Safety & Environmental Protection Headquarters)

We have positioned “Safety, Health and the Environment” as the foundation of management and have established the Safety & Environmental Protection Headquarters to promote initiatives to secure and preserve this foundation. Members of the headquarters consist of the General Manager and co-head of the Safety & Environmental Protection Headquarters, general managers related HSE, the presidents of major affiliated companies and other managers who are appointed by the General Manager, in addition to the secretariat. The executive in charge of safety and environment (a director) is appointed by the President and Representative Director to serve as the General Manager of the Safety & Environmental Protection Headquarters, overseeing the headquarters as the individual bearing the highest responsibility for safety, health, and the environment. The Safety, Environment & Quality Assurance Department serves as the secretariat.

The role of the headquarters is (1) to determine the medium-term management plan, the annual basic policies, and priority issues associated with health, safety and the environment, (2) to assess and evaluate performance through audits, (3) to maintain, review, and improve the Health, Safety and Environmental Management System*, and (4) to instruct all departments and major affiliated companies on how to secure the management resources necessary to establish, implement, maintain, and continually improve these Management Systems. Progress is checked and the basic policies for the Idemitsu Group for the next fiscal year are determined in the Safety & Environmental Protection Headquarters meeting, once a year in December, in principle.

When establishing and reviewing the Medium-term Management Plan, the annual basic policies, and priority issues regarding the Health and Safety Environment (HSE), the secretariat of the headquarters creates a draft proposal in a way that reflects on outcomes of HSE activities undertaken in the preceding fiscal year and takes into consideration the social conditions surrounding HSE issues. The draft is examined at the Safety and Environmental Managers Meeting attended by managers in charge of safety and the environment from each department and then approved at the Headquarters Meeting. After the draft is ruled on by the General Manager of the headquarters, it is finally reported on to the Management Committee. If the Management Committee has instructions or opinions that should be reflected in the draft, the General Manager of the headquarters once again reviews and approves the final version.

The Board of Directors receives reports from the business executives and provides oversight on environmental issues, including climate change.

Environmental Management System

Our Environmental Management System is presented in the diagram below. It is based on a combination of the groupwide PDCA cycle, utilized by the Safety & Environmental Protection Headquarters, and the individual PDCA cycles utilized by each business department.

The Safety & Environmental Protection Headquarters formulates a medium-term management plan for the entire Company and identifies annual basic policies and priority issues based on that plan.

In line with these annual basic policies, each business department develops its own action plan. Each business department operates a PDCA cycle in which it executes business activities based on its action plan, periodically evaluates and reviews these activities, and identifies matters that must be improved and reflected in the action plan for the next fiscal year. Meanwhile, the secretariat for the Safety & Environmental Protection Headquarters carries out an annual evaluation and review of group-wide operations of the Environmental Management System. Matters requiring improvement are discussed at Headquarters Meetings in conjunction with reviews carried out by each business department to ensure continuous improvement. Furthermore, a total of 32 business departments and affiliated companies within the Group (19 in Japan, 13 overseas) acquired ISO 14001 certification as of June 30, 2022.

Safety and Environmental Audits

In order to confirm and promote the HSE activities of each business department and affiliated company, the secretariat of the Safety & Environmental Protection Headquarters conducts Safety and Environmental audits at our refineries and complexes on an annual basis. At business sites other than those named above, Safety and Environmental audits are carried out at a frequency decided in consideration of the worksite’s safety and environmental risks and safety and environmental management status. Should Safety and Environment related issues requiring improvement be discovered by audits, the secretariat will conduct follow-up monitoring on each case and oversee the entire process from the planning of countermeasures to the completion of their implementation. Furthermore, the General Manager of the Safety & Environmental Protection Headquarters conducts Safety and Environment related instructions or safety patrols by visiting business sites. In particular, we have made it a rule for the General Manager of the Safety & Environmental Protection Headquarters to visit our refineries and complexes once a year to undertake these activities.
