Environmental Considerations for Value Chain Management

The Mitsubishi Electric Group promotes various countermeasures that are connected to the realization of a sustainable society. Examples include initiatives to reduce greenhouse gas emissions, efficiently use resources, prevent environmental pollution, and work in tune with nature in each process of the value chain, from procurement, manufacturing and packaging/transportation to use and disposal/recycling.

Initiatives Implemented in Each Process Common Initiatives
Design/Development Implementing Design for the Environment from the perspective shown below

  • Manufacturing process
  • Lifecycle assessments
  • Energy Conservation
  • Packaging
  • Product crushing
  • Service life
  • Logistics
  • Information disclosure
  • Weight reduction
  • Product safety
  • Resource reuse
  • Reusability
  • Recovery/Transport
  • Ease of dismantling/separation of materials
  • Managing Chemical Substances and Emissions Control
  • Coexistence with Nature and Preservation of Biodiversity
Procurement Reducing Environmental Risk through Operation of the Green Accreditation System

The Mitsubishi Electric Group issues Green Accreditation certifications to those suppliers that satisfy its accreditation standards. Certification criteria includes passing evaluations of each supplier’s environmental management system initiatives, compliance with environmental regulations, and management of chemical substances contained in products supplied to the Group. This system has been helping to reduce environmental risk within the Group.
  • Managing Chemical Substances and Emissions Control
  • Coexistence with Nature and Preservation of Biodiversity
Production Promoting Emission Reduction of Four Greenhouse Gases

Mainly four greenhouse gases are emitted during Mitsubishi Electric Group business operations; namely, CO2, SF6, HFC and PFC. Regarding initiatives to reduce CO2 emissions, the focus remains on energy savings at production facilities and utilities. We have been working to reduce other gases by introducing gas abatement systems and switching to refrigerants with a low Global Warming Potential (GWP).
  • Managing Chemical Substances and Emissions Control
  • Coexistence with Nature and Preservation of Biodiversity
Pursuing Reduction in Resource Inputs and Improvement in Waste Materials Final Disposal Rate

We have been reducing the use of resources necessary for manufacturing products by reducing the size and weight of products. Additionally, efforts are being made to recycle waste materials generated during the production processes. This is being accomplished by applying various methods, including conversion to valuable resources through analysis and the thorough separation of waste materials.
Focusing on Reduction of Water Usage at All Business Sites in Japan and Overseas

We are monitoring the use and reuse of water at all of our business sites and implementing measures when necessary. Each site is working to reduce water usage and improve reuse rates, with useful case examples being shared with other sites.
Packaging/Transportation Reducing Use of Disposable Packaging Materials by Practicing the 3Rs: Reduce, Reuse and Recycle

On the basis of our policy to reduce the volume of materials used to ship products, we have been working to simplify packaging (reduce), use more returnable containers and packaging materials (reuse), and recycle used packaging materials (recycle).
  • Coexistence with Nature and Preservation of Biodiversity
Promoting Strain-free, Waste-free, Seamless Product Transportation

We are working to minimize CO2 emissions during product transportation. Our initiatives include switching from trucking to railway and marine transportation (i.e., modal shift), reducing the number of vehicles used through improving load factors, and changing to more efficient logistic routes.
Usage Reducing CO2 Emissions from Product Usage by Improving Product Energy Efficiency

Several tens of times more CO2 is emitted from product usage than production. If power consumption during usage can be reduced, CO2 emissions during product use would also decrease accordingly. Based on this belief, we have been pushing forward with technological innovations in development with the aim of providing highly energy-efficient products.
  • Coexistence with Nature and Preservation of Biodiversity
Providing Information and Solutions in Support of Customers’ Initiatives to Reduce Environmental Load

The Mitsubishi Electric Group is offering information via the Internet and other media as to how to make most of its products use less electricity. In addition, we introducing successful examples products and services that contribute to reducing environmental load, and offering seminars on energy efficient solutions at various locations.
Disposal/Recycling Recovering and Recycling Used Home Appliances at Specialized Recycling Plants

Japan's Home Appliance Recycling Law requires retailers and manufacturers to recover air conditioners, televisions, refrigerators, freezers, washing machines and tumble dryers. These products are recovered and recycled at the home appliance recycling plants of our affiliated companies.
  • Managing Chemical Substances and Emissions Control
  • Coexistence with Nature and Preservation of Biodiversity
Promoting Self-contained Plastic Recycling System

We continue to promote increased use of our self-contained plastic recycling system, in which raw materials recovered from end-of-life home electric appliances are reused in new products. Highly precise separation of different types of plastic fragments after crushing the used products has resulted in our plastic recycling rate rising from around 6% to 70%.
