The UACJ Group is thankful for the Earth’s abundance and life-supporting environment. Recognizing that the Earth is irreplaceable for all living things, we strive to protect the environment and create nature. We evaluate the environmental impact of current and future business activities across our supply chain, set concrete targets based on those evaluations, and take voluntary, proactive action to meet all laws and regulations and to minimize our impact and maximize our contribution to protecting the environment.

Goals

UACJ Environmental Management Activity Policy

Slogan : We are grateful for the lush blue earth, and we will pursue aluminum to contribute to the formation of a sustainable society.

System

Environmental management system

Our company stipulates in its "Sustainability Policy" the basic philosophy and approach for promoting sustainability activities, including climate change measures. The "UACJ Group Basic Environmental Policies" (revised March 2025) also stipulates our environmental "Philosophy" and "Action Guidelines" (including circular economy, climate change measures, and Nature Positive).

As our system for environmental initiatives, we have established an Environmental Committee chaired by the president. Under this committee, six working groups—a controlling organization, a carbon neutral WG, a circular economy WG, a Nature Positive WG, a Green Technology Project (GTPJ), and general environmental management—collaborate to advance initiatives. The results of WG deliberations and activities are reported from the Environmental Committee to the Board of Directors as necessary and receive approval.

Environmental management framework

Environmental Manager Meetings

Environmental managers from UACJ’s three manufacturing bases (located in Nagoya, Fukui and Fukuya), three works (two located in Nagoya and Oyama as well as the Foundry & Forging Works), the extrusion & metal components business, and foil 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.

ISO14001:2015 Certifications (as of June 30, 2025)

• Note Companies and sites as of September 30, 2025.

Eco-Action 21 (as of June 30, 2025)

• Note Companies and sites as of September 30, 2025.

Initiatives

On-site Inspections

On-site inspections are conducted 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.

Status of Compliance with Environmental Laws and Regulations

In fiscal 2024, one accident occurred in which wastewater slightly exceeded the regulatory environmental standard. On September 30, 2024, a regular on-site inspection by Kusatsu City was conducted at UACJ Foil Corporation's Shiga Works. At that time, the mass of n-hexane extracts in the sampled sewer (domestic) wastewater slightly exceeded the standard value. We reported that the main cause was a reduction in wastewater volume due to water-saving measures, which concentrated oil components derived from hand-washing detergent. As recurrence prevention measures, we are implementing detergent improvement, wastewater volume management, and establishment of an inspection system.

Environmental Investment

The UACJ Group’s environment-related investment in fiscal 2024 amounted to approximately ¥320 million. Investments included replacement of DX gas generators (Nagoya Works), renewal of rolling mill coolant piping (Fukui Works), renewal of air-conditioning equipment (all sites), renewal of PCB-containing electrical equipment (all sites), and conversion of ceiling lighting to LED (all 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.
