Reduce CO2 Emissions (Output Level)
Effort Status
- As part of our medium- to long-term environmental policy goals, our CO₂ reduction target—CO₂ being one of the greenhouse gases (GHG)—had been set at a 30% reduction per unit by FY2030 compared to FY2013, up to FY2021. However, in light of the government’s upward revision of its reduction targets in 2021 and changes in the social environment, we established the Carbon Neutrality Promotion Meeting in the second half of FY2021 to review our objectives.
- Beginning with the FY2022 Environmental Policy, we revised our target to: “Achieve carbon neutrality by FY2045, with an interim goal of a 50% reduction in total emission volume by FY2030 compared to FY2013.”
- While our previous target focused solely on unit emissions, the inclusion of total emission volume now calls for more tangible and verifiable improvement results. The results up to FY2023 are shown in the graph below.
- In FY2025, we achieved a 30.5% reduction in total CO₂ emissions, surpassing our 29% reduction target. This was driven by enhanced energy-saving initiatives, installation and operation of solar power systems, purchase of non-fossil certificates, and reduced demand for certain products.
- Each plant holds Environmental Conservation Meetings to identify specific improvement points related to electricity and fuel use in plant infrastructure, products, and production equipment in order to reduce CO₂ emissions.
- These points are then shared at the Company-wide Environmental Conservation Meeting to promote and accelerate improvement initiatives across the entire Group.
Carbon neutrality efforts
We have been advancing our efforts toward carbon neutrality with the goal of achieving net-zero greenhouse gas emissions by formulating reduction roadmaps for each plant, implementing improvements based on our “CO₂ Reduction Master Plan,” adopting solar power, and purchasing non-fossil certificates.
Building on our SBTi certification acquired in April 2026, we will further accelerate emissions reduction across all our business activities while clarifying our greenhouse gas reduction targets in accordance with the SBTi methodology. With FY2030 as our near-term target year and FY2024 as the base year, we have set reduction targets of 42% for Scopes 1 and 2, and 25% for Scope 3, and are working systematically toward our goal of achieving carbon neutrality by FY2050.
To reduce Scope 3 emissions, we will deepen our collaboration with suppliers and work together to reduce emissions throughout the entire supply chain. Furthermore, we will continue to utilize renewable and alternative energy sources to further minimize our environmental impact.
Building on our past initiatives, we remain committed to pursuing activities aligned with SBTi standards and contributing to the realization of a sustainable society.
Specific examples
Example 1 CO2 reduction through fuel improvement
Taking advantage of natural gas pipeline installation near the plant, we switched to natural gas—which has a lower CO₂ emission factor—as fuel for winter heating and surface treatment boilers.
CO2 reduction effect… 27% reduction
Example 2 CO2 Reduction through Melting Power Cost Reduction in Casting Process
We replaced coils used in high-frequency melting furnaces with coils with higher current-carrying efficiency, successfully reducing power consumption.
CO2 reduction effect… 81 tons annually
Example 3 Electricity and CO₂ Reduction through Conversion to LED Lighting
CO2 reduction effect… 55 tons annually
Example 4 Solar power generation effort
- Solar power generation business is ongoing at our group company TPR Total Service Co., Ltd.
- Solar power generation for self-consumption, using factory roof space.
Example 5 Purchase of Non-Fossil Certificates (Value) and Green Electricity (FY2024 Results)
- Nagano Plant: Purchased certificates equivalent to 30% of its FY2013 electricity consumption
- TPR Industry: Purchased certificates equivalent to 8% of its total electricity consumption
- Gifu Plant: Purchased certificates equivalent to 60% of its total electricity
