Environmental Targets and Results

Long-term environment targets

In the interest of protecting the global environment, the Group will work to reduce the environmental impact of all aspects of its corporate activities. Our efforts to build a sustainable world are guided by our vision statement of being “A company dedicated to realizing people’s potential” and “A company sincerely appreciated by all.” We aim to strike a balance between achieving further business growth and contributing to the resolution of social issues, including the creation of a recycling-oriented society and conservation of water resources, in addition to responding to climate change, which is becoming more serious by the year. Accordingly, we have set long-term targets for such environmental issues. The whole Group will work to achieve these goals by promoting environmental conservation activities.

  • CO2 emissions reduction rate (Scope 1 and 2) resulting from the Group’s business activities
  • Rate of reduction of waste (excluding residue, sludge, etc.) resulting from the Group’s manufacturing activities
  • Reduction rate in water intake (amount used) at the Group’s production facilities and reduction rate in wastewater resulting from manufacturing activities
  • Environmental impact of wastewater resulting from the Group’s manufacturing activities

Carbon Neutrality Initiatives

To achieve carbon neutrality in our business activities by 2050, we aim to significantly reduce our Scope 2 emissions, while working on energy conservation activities and the adoption of renewable energy. As part of our energy conservation activities, we will strive to improve the efficiency of our production equipment by developing new production technologies, by switching to the latest equipment, and by installing inverters. Moreover, we will adopt renewable energy technology, such as solar power systems, purchase renewable electricity based on regional characteristics, and utilize green electricity certificates.

To reduce Scope 1 emissions, we plan to electrify Group facilities starting around 2030, when various environmental technologies are expected to become widespread. We aim to achieve carbon neutrality by electrifying our facilities that use fossil fuels such as natural gas, by replacing conventional company vehicles with EVs, and adopting ZEB* standards when constructing or renovating factories.

  • The aim of a Zero-Energy Building (ZEB) is to reduce the building’s CO2 emissions from energy consumption to zero. This is done by adopting renewable energy technology, while realizing significant energy savings and maintaining the quality of the indoor environment
