The “Environmental Policy of the Mitsubishi Materials Group” was established based on the Sustainability Policy and is considered to be the foundation for the business activities of the Mitsubishi Materials Group.

1. Promote Recycling and Provide Environmentally Friendly Products
   We leverage our advanced recycling technologies to promote recycling of waste. At the same time, we provide environmentally friendly materials and products across our business activities starting from raw material procurement to the development, production, distribution, consumption, disposal and recycling of raw materials and products.
    
2. Advance Decarbonization
   We work towards the decarbonization of our business activities by reducing energy consumption. We will also tap into geothermal and other renewable energy sources to decarbonize our entire value chain.
    
3. Respect Biodiversity
   We engage in business activities that take ecosystems into account throughout our value chain, including the development of natural resources.
    
4. Effectively Use and Conserve Water Resources
   We work to reduce water consumption through circular water management and reuse of cooling water, cleaning water and all other water used across our business activities.
    
5. Sustainably Manage Company-Owned Forests
   We make effective use of timber and other forest resources as well as ensure appropriate management of company-owned forests that contribute to decarbonization, biodiversity and water conservation and recreational activities of the local communities.
    
6. Encourage Environmental Education and Harmonious Coexistence with Society
   We strive to reduce the environmental impact from our business activities and prevent pollution by educating all our employees on relevant laws, regulations, and agreements on an on-going basis. We communicate proactively with our stakeholders and engage in environmental conservation initiatives.

1. Significance of Efforts to Conserve Biodiversity
   Based on the Corporate Philosophy "For People, Society and the Earth," we as the Mitsubishi Materials Group have the vision of "Circulating resources for a sustainable future" and, with the mission to "Create a sustainable future (a prosperous, recycling-oriented and decarbonized society)," we have established the following in our Code of Conduct as a rule to observe: "We will work to manage our environmental impact and promote decarbonization, make efficient use of natural resources and accelerate recycling." We also consider the addressing global environmental issues as a Materiality in sustainable growth.
    
2. Basic Principles
   We recognize that our business activities benefit from natural resources such as minerals and water, and we will conduct business activities that minimize the impact on the natural environment in order to pass on these limited resources to future generations.
   In addition, we will conserve forests and closed mines, which are our roots, and the natural environment owned by facilities including renewable energy power plants, which will be the mainstream in the future, as important assets and also raise awareness about biodiversity conservation through community activities.
   Through these activities, we will promote biodiversity conservation activities to contribute to a nature-positive society.
    
3. Focused Areas
   • Assessment of the impact of business activities and raw material procurement on biodiversity
   • Demonstration of the biodiversity conservation functions through maintenance of company-owned forests and management of closed mines
   • Provision of opportunities to interact with nature
   • Effective use of resources and reduction of the impact on the ecosystem through metal resource recycling
   • Ecosystem conservation through climate change measures
   • Compliance with environment-related laws and regulations in operations, etc.
      
4. Approaches
   We will monitor the status of ecosystems and biodiversity at each business site, company-owned forests, closed mines, etc. In addition, we will ascertain the dependence and impact of our business (operations), including the supply chain, on the ecosystem, prioritize them and take appropriate measures.
   To take measures, we will establish action targets to "avoid," "reduce" and "recover and regenerate" concerning substances that have an impact on nature and build an appropriate monitoring system in cooperation with local residents and experts.
