Carbon Neutrality Initiatives

JATCO aims to achieve carbon neutrality across its entire value chain by 2050, focusing on initiatives in the four areas of entire life cycle, production, product development, and environmental activities.

Carbon Neutral Steering Committee

In order to formulate strategies and assess progress towards realizing carbon neutrality, the Committee, with the participation of the responsible executives in four areas and the CEO as the chairman, aims to quickly solve problems and invigorate companywide activities through support and decision-making.

FY2024 CO₂ emissions results (Global)Unit：t-CO₂

Supply chain area (Logistics)

With the aim of reducing CO₂ emissions, JATCO utilizes green logistics when transporting parts. From 2013 to 2024, we achieved an 11% reduction in CO₂ emissions. In order to reduce the CO₂ emissions resulting from the transportation of our parts, we have been implementing a modal shift in our logistics, while working to obtain the acceptance of our customers in Japan.
Specifically, starting from FY2009, we switched from trucks to railcars for transporting procured parts for the route from Hiroshima(approximately 780 km away) to Shizuoka, where JATCO’s production bases are located. As a result, we were able to reduce our CO₂ emissions by 83.3%.
Additionally, since September 2019, we have introduced double trailer trucks to transport JATCO production parts from the JATCO Fuji area to the Kyoto Yagi plant, and transporting at a high load factor led to a reduction in CO₂ emissions.
We will continue to pursue this modal shift and work to improve load efficiency to achieve environmentally friendly parts transportation.

CO₂ emissions per unit in transportation

Production area efforts

Consolidation and shutdown
of heat treatment furnacesApprox.
1,659 t-CO₂/year

In the plant's heat treatment process, we are managing the load factor of each furnace for quenching and tempering treatments, while also shutting down conventional gas carburizing furnaces with poor efficiency and consolidating operations into vacuum carburizing furnaces.
We are working to reduce CO₂ emissions through effcient furnace operation.

Consolidation of molten
metal transportation
at Fuji Area 3 foundryApprox.
820 t-CO₂/year

At Fuji Area 3 Plant, each foundry (No. 2 Foundry and No. 3 Foundry) had its own melting furnace, and the molten aluminum was used only within each respective foundry.
By introducing necessary equipment such as pots, we have made it possible to transport molten metal from the No. 2 Foundry to the No. 3 Foundry, achieving improved efficiency through consolidation.

Power consumption visualization dashboard

With the aim of raising carbon neutrality awareness, we set up apower consumption visualization system that shows the status of plant power consumption and a CO₂ emissions visualization systemon our internal portal site.
All of our employees can easily check the amount of electricity used in each area, thereby leading to self-initiated energy saving.

Optimized steam supply for
Fuji Areas 2, 3, 4, and A PlantsApprox.
1,081 t-CO₂/year

In the plant's heat treatment process, we are managing the load factor of each furnace for quenching and tempering treatments, while also shutting down conventional gas carburizing furnaces with poor efficiency and consolidating operations into vacuum carburizing furnaces.
We are working to reduce CO₂ emissions through efficient furnace operation.

Solar carport at Yagi Area
parking lotApprox.
1,659 t-CO₂/year

As part of efforts to introduce renewable energy, JATCO has installed a solar carport at the Kyoto Yagi Area parking lot under a solar power purchase agreement (PPA) model.
It is expected to cover approximately 2.8% of the electricity consumed at the facility.

Airless model line

In the new line at Fuji Area 4 Plant, the airless concept was incorporated into the line concept at the project stage and integrated into the equipment design. Some model lines have achieved all-electric operation, with an expected 70% reduction in CO₂ emissions. While we have only achieved all-electric operation on some lines at present, we are also adopting the airless concept partially in other lines.

Co-development and production launch of electricpowertrain X-in-1

JATCO is co-developing and producing the electric powertrain X-in-1 for electric vehicles (EVs) with Nissan Motor Co., Ltd., contributing to decarbonization.

Comprehensive efforts

Reuse of Nissan LEAF batteries, solar powered outdoor lighting

JATCO has changed its Fuji Area 1 Plant and HQ Area outdoor lighting equipment to solar power specifications, achieving zero CO₂ through zero commercial power.
The CO₂ reduction effect is 0.8t-CO₂/year/unit and the storage batteries reuse Nissan LEAF batteries, also contributing to the circular economy.
In an emergency, the batteries can be removed and used as a portable power source for disasters (capacity of 40.000 mA).

Partnership agreement for realizing Fuji City Zero Carbon City

In October 2023, JATCO concluded a Partnership Agreement with Fuji City to realize the Fuji City Zero Carbon City initiative, which aims to achieve net-zero greenhouse gas emissions in Fuji City by2050. We report our greenhouse gas emission reduction targets and results to Fuji City. Additionally, JATCO’s activities are featured in Children’s Zero Carbon Challenge, an environmental awareness booklet distributed to fourth-grade elementary school students in the city.

Implementing a green curtain project

At our Yagi Area in Kyoto we are implementing a green curtain project by growing vines around the plant building to block direct sunlight. By using plants to block the sunlight, we are reducing the generation and penetration of radiant heat.

Use of energy-efficient equipment and visualizationof power consumption

At the Fuji Area office building, we have implemented measures to make it possible to see conference rooms’ CO₂ emissions at a glance, thereby promoting activities to enhance energy conservation awareness.
