Approach to Environmental Management

To advance environmental activities and raise the environmental awareness of employees, the UACJ Group has established the Environmental Committee as a body that represents the entirety of the Group.

The Environmental Committee, chaired by the President, has a membership consisting of UACJ executives, chief executives, plant managers, and presidents of principal Group companies. Beginning in fiscal 2024, the committee working groups, including the newly created circular economy, nature positive, and environmental management groups, meet three times a year to provide updates on the status of environmental activities, and discuss aims and objectives for the following fiscal year’s environmental activities.

To link environmental activity objectives with business activities and reliably work for their achievement, we have established the Safety & Environment Department as a unit responsible for implementation. The Safety & Environment Department holds meetings for Environmental Managers, conducts environmental inspections, and organizes subcommittees on topics such as reducing greenhouse gases and industrial waste in performing the function of implementing and refining environmental activities.

Environmental Manager Meetings

Environmental managers from UACJ’s three manufacturing plants, the extrusion & metal components business, foil business, and casting and forging business participate in Environmental Manager Meetings to confirm the Group’s progress toward its environmental targets and to exchange information on revisions to laws and regulations.

Environmental Management System

Environmental management systems are in place at each of the UACJ Group’s business locations, and nearly all of our plants have obtained the ISO14001 certification. Some of our smaller business locations have obtained the Eco-Action 21 certification by following the guidelines formulated by Japan’s Ministry of the Environment.

Following the September 2015 issuance of the updated ISO14001 standard, each business location worked to achieve compliance with the new standard. All locations successfully updated their certifications by the July 2018 deadline for doing so.

On-site Inspections

On-site inspections are conducted by officers at Group business sites in Japan to prevent environmental troubles, formulate and promote execution of measures to reduce and eliminate risks, and to ensure full compliance with environmental laws and regulations.

Inspection teams consisting of environmental officers and members of the Safety & Environment Department visit the business sites and utilize a site’s environmental reports and on-site verification to inspect the status of compliance with laws and regulations and the progress of improvement measures. The Safety & Environment Department provides guidance and support for issues that need to be addressed. The inspections are part of our efforts to raise the Group’s level of environmental management.

In fiscal 2022, on-site verifications were conducted at 24 business sites in Japan and inspections were conducted via online meetings at 7 business sites overseas.

Status of Compliance with Environmental Laws and Regulations

In fiscal 2022, we recorded 1 incident of wastewater discharge exceeding environmental regulatory standards.

On July 15, 2022, the oil concentration in wastewater discharged from the wastewater treatment facility at the employee cafeteria of the UACJ Nagoya Works increased above the regulatory standard. The incident occurred when the restaurant operator cleaned oil stains on a kitchen ventilation fan filter with cleanser in a sink. The oil and water were then allowed to flow down the drain, and the amount of oil exceed the treatment capacity of the wastewater treatment facility. To prevent recurrence, we changed the standard process to have ventilation fan filters cleaned by an external cleaning company with the ability to properly treat the wastewater from the process.

Status of Compliance with Product Safety Laws and Regulations

In fiscal 2022, there were no cases of noncompliance with laws, regulations, or voluntary controls related to product quality, safety, or information labeling.

Environmental Investment

The UACJ Group invested approximately ¥800 million in environmental projects in fiscal 2022. Projects included updating the deodorization units (UACJ Aluminum Center Corporation, Utsunomiya Color Aluminum), installing new air conditioning equipment (all business sites), replacing parts of furnaces and converting fuel sources (all business sites), updating water supply and fire hydrant piping (UACJ Foil Corporation, Nogi), and updating electrical equipment that use PCB (all business sites).

Environmental Education

We conduct environmental education for all employees as another measure for fulfilling our social responsibility to protect the global environment.

The Safety & Environment Department and the environment units of individual business locations lead environmental education initiatives. The Safety & Environment Department conducts fundamental environmental education activities, the purposes of which are to enlighten and raise awareness of environmental protection, and promote understanding of the UACJ Group’s Basic Environmental Policies. Meanwhile, the environment units of individual business locations carry out environmental education initiatives to foster the skills and numbers of internal auditors needed to ensure that each business location conducts its daily activities with sensitivity toward the environment.

We encourage employees to obtain public qualifications in environmental fields and are developing a workforce that is capable of appropriately responding to trends in environmental regulation. Individual business locations conduct general environmental education programs and special education programs for employees engaged in work that could have significant environmental impacts.
