Our Approach to ESG and Sustainability

Mitsubishi Materials Group's Business Activities and the SDGs

Our Business and SDGs

Universal Long-Term Goals for the International Community

In September 2015, the UN unanimously adopted the 2030 Agenda, a plan to eliminate poverty, unfairness and injustice wherever possible, protect the environment, and create a better future. One of the key features of the agenda was the Sustainable Development Goals (SDGs), which set out a vision for how the world should be by the year 2030. Following on from the Millennium Development Goals (MDGs), which the international community had been working on for 15 years since 2001, the SDGs are positioned as universal goals applicable to all countries.
Rather than relying solely on national governments, the SDGs also require companies and members of the public to take action all over the world. The SDG Compass is a guide to show companies how they should be using the SDGs, published jointly by the Global Reporting Initiative (GRI), UN Global Compact, and the World Business Council for Sustainable Development (WBCSD). It provides the following explanation.
“Unlike their predecessor, the Millennium Development Goals, the SDGs explicitly call on all businesses to apply their creativity and innovation to solve sustainable development challenges. The SDGs have been agreed by all governments, yet their success relies heavily on action and collaboration by all actors. The SDGs present an opportunity for business-led solutions and technologies to be developed and implemented to address the world’s biggest sustainable development challenges.”


The Group’s Business Activities and the SDGs

We intend to incorporate the SDGs into our strategies from the point of view of both comprehensive efforts to increase business competitiveness, and the creation of new products and businesses. We will also be actively working with a wide range of outside partners as we strive to achieve a balance between social value and economic value.
Of the 17 goals set out under the SDGs, numbers 7 (energy), 8 (growth and employment), 9 (innovation) 11 (cities), 12 (production and consumption) and 13 (climate change) in particular tie in with areas in which we are implementing priority initiatives.
The adoption of the SDGs by the UN has reaffirmed that we are going in the right direction with our business activities as a group, and provided us with a springboard from which to assess critical long-term risks and opportunities, in terms of issues that we need to address and the path we need to take in the future.
The Mitsubishi Materials Group is a diversified material manufacturer with the corporate philosophy "for People, Society and the Earth." We are also committed to achieving our vision – “We will become the leading business group committed to creating a sustainable world through materials innovation, with use of our unique and distinctive technologies, for People, Society and the Earth.”

"MEX," a New Platform for the E-Scrap Business, Starts Operation
— Applying DX to be a Leading Company Offering High Value-Added Products and Services —
(Announced on October 26, 2021)

We have developed "MEX" (Mitsubishi Materials E-Scrap EXchange), a new platform for the E-Scrap business, and have started our operation on December 20th, 2021. This is the first achievement of the Business DX in MMDX (Mitsubishi Materials Digital Business Transformation), the digitization strategy we pursue.

By taking advantage of the Mitsubishi Process for continuous copper smelting*, a unique copper smelting technology that has achieved the industry's top environmental impact reduction performance, as our strength, we have long accepted and processed E-Scrap (such as discarded circuit boards of various electronic devices containing high concentrations of gold, silver, copper, palladium, and other valuable metals) and currently boast the world's number one E-Scrap acceptance and processing capacity of approximately 160,000 tons annually. The E-Scrap market is expected to continue to grow, and we plan to further increase the E-Scrap acceptance and processing capacity to approximately 200,000 tons annually by the end of fiscal 2031.

Against this backdrop, we have started operation of "MEX," a new platform for E-Scrap trading, starting on December 20th, 2021, to further improve our customer service. "MEX," which was developed as part of the MMDX initiative, is equipped with many features making use of the latest digital technology. First, customers are provided with around-the-clock access to all information required for E-Scrap trading. It has an inquiry feature that accepts questions anytime and allows interactive communication by dealing with frequently asked questions using e-mail or a chatbot under development capable of automatic responses. Our platform also has enhanced security by such means as adoption of two-step authentication. These various improvements will facilitate use of this platform by overseas customers and other customers who were not readily able to use our platform. In addition, we plan to make further functional additions through future updates.
We aim to be an accessible partner for all customers in Japan and overseas by offering our long-standing experience and high technological capabilities through "MEX."

  • The Mitsubishi Process for continuous copper smelting
    A copper smelting process in which, S (smelting) furnace, CL (slag cleaning) furnace, C (converting) furnace, and a refining furnace are connected by enclosed launders to make a series of batch operations. This results in a facility that is compact, conserves energy, and operates at a low cost. A non-polluting system has also been established in which sulfurous acid gas leaks are prevented and efficiently processed in an exhaust gas treatment plant.

Notice Concerning Revision of Greenhouse Gas Emissions Reduction Target
- Aiming to Achieve Carbon Neutrality Five Years Earlier than the Original Goal -
(Announced on November 26, 2021)

We have revised the greenhouse gas (GHG) emissions reduction target for the group, including direct emissions by the business operator (Scope 1) and indirect emissions resulting from the use of supplied energy (Scope 2), in pursuit of reducing GHG emissions by 47% by FY2031 (compared to FY2014) and to virtually zero, or carbon neutrality, by FY2046.

In March 2021, we set a mid to long-term target for our group to reduce GHG emissions by 17% by FY2031 (compared to FY2014) and to become carbon neutral by FY2051. A month later, the Japanese government announced a GHG emissions reduction target of 46% by FY2031 compared to FY2014, and actions on climate change are becoming increasingly important. Under the circumstances, we revised the reduction targets for our group and decided to take on new initiatives as follows to reinforce our actions on climate change.

  • We aim to achieve carbon neutrality by FY2046 (five years earlier than FY2051, which we announced in March 2021).
  • The intermediate target announced in March 2021, which is the GHG emissions reduction target (Scopes 1 and 2) by FY2031, was also increased to 47% compared to FY2014. Specifically for Metalworking Solutions business, ahead of other businesses, we set a target to switch all power used in manufacturing to practically CO2 emission-free electricity by FY2031, and to promote manufacturing activities to contribute to our customers as their "Global Craftsman Studio".
  • As for Scope 3 that includes business partners' GHG emissions, which is the emissions of the entire supply chain excluding Scopes 1 and 2, we started to collect actual data from FY2021. While working to improve calculation accuracy by sharing information with our business partners, we will project long-term reduction in consideration of their GHG reduction plans, etc.
  • We will begin to evaluate and utilize the carbon footprint of products (CFP)* and work to estimate GHG emissions of the products using recycled materials such as tungsten and copper scrap.

*Please note that the targets published above do not include the cement business, for which business integration with UBE Corporation was conducted in April 2022. Specific effective GHG reduction measures for the same business will be established by the new company after the business integration.

Setting of New Greenhouse Gas Emission Reduction Targets

  • ※ Regarding greenhouse gas emission reduction targets due to the organizational change on April 1, 2022, we have announced new targets that exclude the aluminum business as well as the cement business.


  • * Carbon footprint of products (CFP) are the evaluation items related to GHG emissions extracted from LCA (Life Cycle Assessment), a method to quantitatively evaluate input resources, environmental load, and their environmental impact within a product life cycle.
Mitsubishi Materials Group Sustainability Policy Established
- Actively and Positively Promote Initiatives for Realizing a Sustainable Society -
(Announced on December 1, 2021)

As of December 1, 2021, we have established a fundamental policy regarding sustainability.

To clarify our attitude for actively and positively promoting sustainability as a Group based on our Corporate Philosophy and Vision, we have newly established a Sustainability Policy. This policy is positioned as a superordinate policy governing rules and policies relating to sustainability.

Based on this policy, we have also established a Human Rights Policy and a Procurement Policy. We consider respect for human rights to be the foundation of the business activities of the Mitsubishi Materials Group, and we will work to expand and deepen our initiatives by respecting the principles enshrined in international human rights instruments. We will also strive for sound procurements.

Furthermore, we have established provisions in the Sustainability Policy and Human Rights Policy regarding the promotion of diversity and inclusion. We embrace diversity and acknowledge its importance in creating new value by promoting it as a source of sustainable growth within the Group. To that end, we will renew existing targets or set new ones concerning the ratio of women, non-Japanese, and mid-career employees etc. in managerial positions and strengthen our initiatives through various measures.

Participation in NEDO's Green Innovation Fund Project/Development of Next-Generation Solar Cells
- Towards Developing Peripheral Materials to Reduce Costs and Improve Performance of Perovskite Solar Cells -
(Announced on January 20, 2022)

We are pleased to announce our participation in the Green Innovation Fund Project/Development of Next-Generation Solar Cells (the Project) by the New Energy and Industrial Technology Development Organization (NEDO) as a company commissioned by EneCoat Technologies Co., Ltd. (EneCoat Technologies), which it finances through the MMC Innovation Investment Limited Partnership (our CVC).

A perovskite solar cell is a type of solar cell formed by applying a layer of perovskite crystal* on a substrate, and it is expected to become widely used as the next-generation solar cell because it is lighter than the crystalline silicon solar cells commonly used at present, enables the thickness to be reduced to about 1/100, and can be folded or bent for installation in various places. EneCoat Technologies, a startup originating from Kyoto University, is working on its development. EneCoat Technologies is also developing a low-lead solar cell by replacing the lead contained in perovskite solar cells with an alternative material.
We financed EneCoat Technologies in May 2020 through our CVC and we are examining collaboration with them regarding technologies that will contribute to improving the durability of perovskite solar cells and development of the peripheral materials required for eliminating lead.

In the course of these developments, EneCoat Technologies has recently been selected for the Project based on the theme "development of technology for the practical application of perovskite solar cells featuring a high degree of installation freedom." Towards adopting solar power generation in places where installation of the existing types of solar cells has not been possible, such as for example on the roof of a small factory or a wall of a building with low load capacity, the Project aims to achieve the practical application of perovskite solar cells, which not only realize weight reduction and provide sufficient flexibility for installation on curved surfaces of buildings but also compare favorably with existing types of solar cells in terms of performance including conversion efficiency and durability. We participate in the Project as a company commissioned by EneCoat Technologies and work on the development of peripheral materials to reduce costs and improve performance for the purpose of facilitating the wide use of perovskite solar cells.
