Approach to Combatting Climate Change

Based on the action guidelines of its basic environmental policies, the UACJ Group recognizes its social responsibility as a comprehensive aluminum products manufacturer to take proactive steps to combat climate change and contribute to decarbonization. Accordingly, the Group will work to contribute to achieving the goal set by the Paris Agreement to limit the global average temperature rise to 1.5 degrees Celsius above pre-industrial levels, or at least hold this increase well below 2 degrees Celsius. Towards this end, the Group will scientifically monitor the impact of greenhouse gases (GHG) emitted from its operations on global climate change, and on that basis, carry out initiatives in line with the following action guidelines.

Information Disclosures Based on the TCFD Recommendations


The UACJ Sustainability Basic Policy stipulates the company’s basic concepts and approaches for its climate change and sustainability activities.

The Climate Change Countermeasure Steering Committee, established on April 1, 2021 was renamed the Environmental Committee in fiscal 2024. Chaired by the president, the committee organizes working groups for specific initiatives, including carbon neutral measures, recycling, conversion to aluminum, and procurement of raw materials, and in fiscal 2024 added initiatives for circular economy, nature positive, and environmental management. The committee reports important results of the working group’s examinations and activities at management meetings and the board of directors to receive the decisions of management, which conducts direct governance of its activities.


In our scenario analysis of climate change countermeasures, we considered risks and opportunities along the entire value chain from raw material procurement to disposal and recycling. We focused on the flat rolled products business of the Rolled Aluminum Products segment because it is a representative field of our business and is highly important in our business portfolio.

Following the recommendation of the Task Force on Climate-Related Financial Disclosures (TCFD) to analyze several climate change scenarios, including for a temperature increase of 2 degrees Celsius or less, we analyzed scenarios for increases of 4 degrees Celsius (2.6°C-4°C) and 1.5 degrees Celsius, which were based on projections by the International Energy Agency, the Intergovernmental Panel on Climate Change of the United Nations, and other organizations.

The 4 degrees Celsius scenario analysis indicated a negative impact even if additional response measures were implemented and new business opportunities appeared. The 1.5 degrees Celsius, which also included additional response measures and new business opportunities, indicated a significant positive impact for our business. Realizing this scenario will require speeding up decarbonation efforts, such as increasing renewable energy usage. We plan to do our part through various initiatives, including installing one of the world’s largest rooftop solar power generation systems at UATH and converting our heat treatment furnaces in Japan from LPG and heavy oil to LNG.

Action Plans and Details

Scenario Analysis Covering All Group Companies
  • The current scenario analysis focused on the flat rolled products business and the operations in Japan and Thailand. The analysis methods used will be developed to cover all Group companies.
  • The project team will be used to lead task forces and working groups to be deployed throughout the Group and at all levels of business.
Monitoring and Execution System
  • The current analysis focused on two scenarios. Given the high degree of uncertainty surrounding climate change, we will regularly monitor forecasts, conduct impact assessments, and review our strategies.
  • A special team was formed for the project to address climate change risk. We intend to give the team an official organization role to ensure the initiative remains a permanent part of our operations.
Increasing the Depth of Analysis
  • We consider the current scenario analysis to have been Level 1, and we intend to incrementally deepen the analysis to Level 2 and Level 3.

Risk Management

A TCFD Response Team that has been set up within the secretariat of the Environmental Committee is tasked with identifying risks and opportunities in line with the TCFD framework, and creating scenario road maps. As UACJ has a policy of addressing climate change as a unified Group, the TCFD Response Team includes members from broad cross-section of organizations within the Group, including sales, manufacturing, legal, risk management, public relations, sustainability promotion, and the finance division.

Voluntary Participation in the CDP

By voluntarily participating in the Carbon Disclosure Project, an international climate change initiative, we are furthering our activities to fight climate change while gaining an objective way to evaluate our greenhouse gas management. As one example, we are following the Greenhouse Gas Protocol’s definitions for scope 1 (Direct GHG emissions from the burning of fuel internally), scope 2 (Indirect emissions from the generation of purchased electricity used internally), and scope 3 (Upstream and downstream emissions throughout the supply chain) in categorizing and calculating greenhouse gas emissions, and disclosing them on our website.
