Initiatives to Reduce Environmental Impact
CO2 Reduction and Energy-Saving Initiatives
Our Group promotes energy-saving initiatives to reduce GHG emissions. We are working to improve the efficiency of energy use and reduce CO2emissions through more efficient and optimized operation of production equipment and utility facilities.
We will continue our energy-saving initiatives to further reduce GHG emissions.
Air leak improvement case study (Head office Plant)
We are continuing our efforts to improve air leaks and strengthening the energy management of our compressed air equipment. To reduce energy loss due to the aging of compressed air piping and connected equipment we have introduced electrically operated pipe switching valves to suppress the supply of unnecessary compressed air when the equipment is not in operation. We are working to conserve energy and reduce CO2 emissions through both continuous improvement activities and the implementation of energy-efficient equipment and systems. The results of this initiative are being shared at information-sharing meetings with Group companies, and the introduction of similar initiatives is being considered.
Furthermore, we analyzed the operational status and power demand within our facilities and optimized the operation of transformers at our Hiroshima plant. By consolidating equipment loads, we reduced the number of transformers in operation and lowered fixed losses, resulting in energy savings and a reduction in CO2 emissions (-15%). We are working to improve power usage efficiency while making effective use of existing equipment.
Utility Improvement Case Study (Head Office Plant)
As part of our energy-saving efforts to achieve carbon neutrality, we are working to improve the efficiency of our compressed air supply equipment. The amount of air required by compressed air equipment varies significantly depending on production conditions. Previously, however, the air supply could not be sufficiently adjusted to changes in demand, resulting in energy loss from supplying more air than necessary. Therefore, we have introduced inverter-controlled compressors that enable optimal operation in response to demand fluctuations, achieving efficient air supply tailored to usage conditions. This has improved the energy efficiency of the entire compressed air system and reduced electricity consumption, while also contributing to the reduction of CO 2 emissions.

Energy saving through relocation to the Kameyama Plant (Kameyama Division PP Plant)
In July 2023, we transferred the manufacturing of pressure plates (PP), a key component of our clutch covers, from our Ueno Division to our Kameyama Division. At the Kameyama Division, in addition to introducing state-of-the-art equipment, we eliminated the pressurized holding furnace in the casting process and instead poured molten metal directly from the melting furnace into the ladle and then into the sand mold, resulting in a 12% reduction in electricity consumption compared to the old plant. Furthermore, while kerosene burners were previously used in the sand mold pouring process, the new plant has eliminated kerosene use through improvements in the dust collector's capacity.
(Reduction equivalent to 226 t-CO2 /year)

Installation of insulation jackets for heat treatment furnaces (Ueno Division, TC North Plant)
In AT Manufacturing Group, we are implementing the installation of insulating jackets on heat treatment furnaces in the heat treatment (brazing) process of torque converters, our main product, in order to reduce energy loss. By effectively suppressing the heat emitted from the equipment, we are reducing electricity consumption, and by fiscal year 2025, we have achieved annual energy savings of approximately 157,000 kWh and an annual reduction of approximately 78.2 t-CO2 emissions.
We will continue to contribute to the realization of a decarbonized society through the introduction and improvement of energy-saving equipment.

After the jacket is insulated, the temperature is 20°C higher than when it is not worn, demonstrating its insulation and heat-retention effects.
Energy-saving activities for production equipment (MT Manufacturing Group)
We are promoting energy conservation in pumps used in production equipment. Pumps are used in many manufacturing facilities, including hydraulic presses and cleaning equipment, but they continue to operate even when the equipment is idle, resulting in power loss. Therefore, we introduced inverter-based speed control to optimize pump capacity according to the operating conditions of the equipment. As a result, we are reducing power consumption during standby while maintaining equipment performance and productivity, thereby contributing to improved energy efficiency and reduced CO2 emissions.

Other CO2 reduction and energy saving activities
Implementation of internal carbon pricing (EXEDY)
We use internal carbon pricing (ICP) in investment decisions to promote investment in energy-efficient equipment. Our Group companies are also working to utilize renewable energy, including solar power generation systems.
We will continue to reduce GHG emissions through energy-saving initiatives and the use of renewable energy.
- Unit price: 14,000 yen/t-CO2 (FY2025)
- Unit price setting: Calculate and set the present value based on the IEA WEO2021 SDS scenario
- How to use ICP: CO 2 Used in investment decisions for investment projects that have cost-saving effects.
(The ICP amount corresponding to the reduction effect is added to the investment return, thereby shortening the payback period.)
Utilization of renewable energy (Dynax)
Dynax Corporation is actively working to utilize renewable energy sources, including by installing solar panels, introducing solar carports, and introducing biomass boilers.

Waste Reduction Initiatives
To promote a circular economy, EXEDY Group is working to make effective use of resources and reduce waste. Each Group company aims to reduce the amount of waste disposed of by an average of 1% annually compared with the previous fiscal year, either on a per-unit basis or in total volume, and continues to implement waste reduction initiatives. Through these efforts, we aim to promote resource circularity and minimize our environmental impact.
Improvement Examples at the Head Office Plant
Packaging Improvement Example - Replacing wooden pallets with plastic pallets
At our company, we are continuously working to reduce the environmental impact of our logistics processes by promoting the reuse of wooden pallets and improving packaging. By extending the lifespan of pallets and promoting repeated use, the amount of wooden pallet waste in fiscal year 2025 is projected to be 58.7 tons, a reduction of approximately 24 tons (approximately 29%) compared to fiscal year 2019. These efforts not only reduce waste generation but also contribute to the effective use of wood resources and the promotion of resource recycling.
We will continue to review our logistics materials and improve transportation efficiency, working to reduce the environmental impact throughout the entire supply chain.
Review of shipping materials (Head Office TM Plant)
For the fastening materials used when shipping products, we use environmentally friendly materials that make effective use of recycled plastics. This material has the same workability as wood, while possessing high durability and corrosion resistance. While conventional wooden fastening materials needed to be replaced approximately every three years, these materials have been in use without any problems as of July 2026, 3 years after their introduction. This reduces the frequency of material replacement, leading to a reduction in material usage and waste. Furthermore, by utilizing materials m English
