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 FY2024, we achieved a 30.9% reduction in total CO₂ emissions, surpassing our 26% 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 aim to achieve net-zero greenhouse gas emissions from our business operations by FY2045.
This means achieving carbon neutrality in both Scope 1 (direct emissions) and Scope 2 (indirect emissions). Each plant has formulated a reduction roadmap through FY2045, clearly outlining what actions will be taken when, and is steadily implementing each action step by step.
In addition, with a CO₂ Reduction Master Plan, we organize the reduction volume, responsible personnel, costs, and schedule for each improvement point, enabling systematic progress toward our goals. Looking further ahead, we aim to achieve carbon neutrality that includes Scope 3 emissions across our supply chain by FY2050.
To realize this goal, we work together with our suppliers and support their specific reduction initiatives. While it is difficult to completely eliminate the use of electricity and fuel, we continue to minimize our environmental impact by adopting alternative energy sources such as solar power generation and purchasing non-fossil certificates.
Through these efforts, we are committed to minimizing our environmental footprint and passing on a rich and sustainable natural environment to future generations.
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
