Our Approach to ESG and CSR

Mitsubishi Materials Group's Business Activities and the SDGs

Our Business and SDGs

Universal Long-Term Goals for the International Community

In September 2015, all 193 members of the UN signed up to 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.”

Setting greenhouse gas emission reduction targets and analyzing scenarios for climate-related risks and opportunities (Goal 13)

We have set a reduction target to achieve carbon neutrality with effectively zero greenhouse gas emissions across the Group by fiscal 2051. At the same time, we conducted a scenario analysis of the impact of climate-related risks and opportunities on our business and finances based on the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD).
In order to achieve our mission of contributing to building a decarbonized society, we have recently set the medium and long-term targets of reducing the Group's overall greenhouse gas emissions by at least 17% by fiscal 2031 (in comparison with fiscal 2014), and achieving carbon neutrality by fiscal 2051. In particular, in our product-type businesses (Advanced Products Business and Metalworking Solutions Business) we will work actively to reduce greenhouse gas emissions, with the goal of reducing emissions by at least 30%by fiscal 2031. As one of our reduction measures, we have set the goal of supplying at least 20% of the electric power used in the Group's businesses with renewable energy by fiscal 2031.

Medium and long-term goals regarding reduction of greenhouse gas emissions


  • *1 Scope1+Scope2
  • *2 Transition to a production process that utilizes hydrogen/electric energy
  • *3 Cement business: Does not include impact of April 2022 business integration.

• Scope 1: Direct GHG emissions by business operators

Capture and using utilization of CO2 emitted from plants —A demonstration launched in Kyushu— (Goal 13)

We are advancing the development of CCU (carbon capture and utilization) technology using carbon dioxide (CO2) emitted from the Group's plants. Having set ourselves the mission of contributing to building a decarbonized society, as one part of our vision for the future, we have established the medium and long-term targets of reducing the Group's overall greenhouse gas emissions by at least 17% by fiscal 2031 (in comparison with fiscal 2014), and achieving carbon neutrality by fiscal 2051. With these targets in mind, we are working to develop technologies for synthesis of methane and various other products by separating and recovering CO2 emitted from manufacturing processes using cement firing kilns or other high-temperature heating furnaces and reacting it with hydrogen. In July 2021, we started demonstration tests at the Kurosaki Production Section, Kyushu Plant. Moving forward, we will also work to develop technologies for reusing the methane, etc., obtained in this way as a source of thermal energy for cement manufacturing. Through these kinds of initiatives, we will recover and use CO2 emitted from manufacturing processes using cement firing kilns or other high-temperature heating furnaces, for which it is difficult to reduce emissions with conventional energy-saving measures and electrification. By using carbon-neutral thermal energy in this way, we will attempt to reduce the consumption of coal and similar energy resources to reduce CO2 emissions from our cement plants. In the future, we will advance our technology development efforts for a wide range of applications, including conversion to other valuable substances aside from methane.

Investment in a perovskite solar cells startup from Kyoto University (Goal 7)

Through the MMC Innovation Investment Limited Partnership* a corporate venture capital investing primarily in venture companies with materials technologies, we have invested in Enecoat Technologies Co., Ltd., which aims to market perovskite solar cells.
Perovskite solar cells are a type of solar cell formed by applying layers of perovskite crystals (crystals with the same structure as calcium titanate, the mineral perovskite discovered by Russian researcher Lev Perovski) etc., to a substrate. They are lighter in weight and can be formed with around 1/100th the thickness of crystalline silicon solar cells currently in typical use. They are also bendable and can be installed in a diverse range of locations, and are therefore expected to gain widespread popularity as the next generation of solar cells. In addition to working to develop perovskite solar cells with higher power generation efficiency and durability, the Kyoto University startup EneCoat Technologies is currently also advancing the development of lead-free solar cells, that will replace the lead contained in those solar cells with alternative materials.
In addition to investing in EneCoat Technologies, we collaborate with this company in researching and developing technologies that help improve the durability of perovskite solar cells and the peripheral materials needed to make them lead-free, among other things. In this way, we will continue to make uncompromising efforts to ensure manufacturing focused on reducing environmental impact.
