GHG Net-zero in the product life cycle
Basic approach
Instead of focusing only on the reduction of CO2 emissions during our auto parts production process, the Toyota Boshoku group takes on the challenge of “achieving GHG Net-zero” in all stages of the product life cycle from production to use, disposal and recycling of products.
Continuing our efforts to reduce the environmental impact of technology R&D
Future vision of Toyota Boshoku
Carbon Neutrality Strategy Roadmap
The Carbon Neutrality Strategy Roadmap is an action implementation plan designed to help us achieve our target of reducing plant GHG emissions by 50% (compared to FY2020 levels) by the year 2030. It was designed with consideration of the actual conditions on the ground across our five global regions of Japan, the Americas, China, Asia, and Europe & Africa. Working together with each region, we are working to examine which improvement items can, or should be implemented globally, and are promoting activities that contribute to the realization of our GHG target.
Going forward, the entire Toyota Boshoku group will continue to take action, and engage in activities that help reduce GHG emissions.
Reduce GHG emissions in the life cycle of Toyota Boshoku products by reducing weights
Toyota Boshoku ascertains GHG emissions in the life cycle of core products, from their manufacture and sale to their usage and eventual disposal, and then takes action to reduce these emissions as a means to promote more environmentally friendly products. Out of all the stages in the life cycle mentioned above, the majority of CO2 emissions arise during a product’s usage. Thus, we put great effort into actions that can improve fuel efficiency and reduce emissions, such as promotion of reductions to the size or weight of products.

Reducing CO2 emissions through lightweighting
It is said that the majority of GHG emissions throughout the life cycle of a vehicle are accounted for when driving. Therefore, we conduct development and design based on the conviction that reducing weight and creating compact designs will contribute to increasing the fuel efficiency of cars and reducing CO2 emissions. In fiscal 2022, lower-profile, comfort-enhancing third-row seats were installed in Toyota’s new NOAH and VOXY models. The conventional metal springs and wires in the third-row seat cushioning have been replaced with fiber cloth springs, which allows improved comfort while riding, as well as thinner overall seating, leading to weight reduction.
Our Decarbonization School, run by Sunshine (a supplier group member of Toyota Boshoku)
Our Decarbonization School has been operating since 2022, with the aim of reducing GHG emissions throughout our entire supply chain.
The school holds lectures by both external consultants and staff from our Carbon Neutral Environment Center on energy saving techniques, and other topics related to decarbonization. It also assists member companies in creating GHG emission reduction targets, and in developing plans to meet their targets, as well as supporting employee development with an eye to cultivating employees with the skills and vision needed for long-term carbon neutral efforts.
As well as classroom lectures, on-site study sessions were also held at the Kariya Plant in fiscal 2023 and at Toyota Boshoku Shiga in fiscal 2024. At the plant, we introduced suppliers to an energy-saving technique related to steam and compressed air used to operate equipment, and to case studies of energy conservation including wrapping pipes with insulation to prevent heat dissipation.
We will continue to work closely with our suppliers to promote carbon neutral initiatives throughout the supply chain.
Scope 3* (Supply Chain Management)
Toyota Boshoku has commenced to calculate the GHG emission of whole Toyota Boshoku’s supply chain in order to reduce the GHG emission from our whole business activities since FY2013.
Next, we will improve the precision of calculating method, and proceed to reduce GHG emission after we evaluate the GHG emission of each category in our whole business activities.
- Scope 3:GHG in both Upstream and Downstream in business
[Upstream] GHG by supply of material, transportation and employees’ transfer
[Downstream] GHG by using and end-of-life treatment of sold products
GHG Emissions Produced by Toyota Boshoku group’s Value Chain
Calculation Criteria
Category | Explanation of each category | Calculating method |
---|---|---|
1. Purchased goods & services | Emissions from production of purchased raw materials, components, etc. | For raw materials, components, etc. purchased at Toyota Boshoku group production sites, figures are calculated by multiplying the costs (in million yen) of each type of raw material, component, etc. by GHG emission coefficient (t-CO2e/millions yen) by raw material type. GHG emission coefficient by raw material type values are taken from the separate emission factor database for corporate GHG emissions accounting over the supply chain (Ver. 3.4, March 2024) published by the Ministry of the Environment (MoE) and the Ministry of Economy, Trade and Industry (METI). |

4. Upstream transportation and distribution | Emissions from procurement logistics and shipping logistics of our shipments | CO2 of procurement logistics from suppliers to Toyota Boshoku group and shipping logistics of our shipments are calculated based on the “Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain” (Ver. 2.6, March 2024), published by MoE and METI, ISO 14083:2023 (“Quantification and reporting of greenhouse gas emissions arising from transport chain operations”), the “Global Logistics Emissions Council (GLEC) Framework V3.0,” and “LCI Database IDEA version 3.3.” |
5. Waste generated in operations | Emissions from the disposal of waste generated in-house | Calculated by multiplying the amount of waste (t) discharged from Toyota Boshoku group offices and plants by the CO2 emission coefficient for each waste type (t-CO2/t). Values for CO2 emission coefficient by waste type (t-CO2/t) are from the “Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain” (Ver. 2.6, March 2024) and the separate emission factor database for corporate GHG emissions accounting over the supply chain (Ver. 3.4, March 2024), both published by MoE and METI, the U.S. EPA “Emission Factors for Greenhouse Gas Inventories 2023,” “Thailand’s Emission Factor,” the “Indonesia_climate-change-roadmap-waste-sector” and the “UK Government GHG Conversion Factors for Company Reporting Ver.1.1.” |

Basic units calculated in-house are calculated based on fiscal 2020 disposal figures for the categories of seats, interior and exterior parts, and unit components. |
15.

Reducing CO2 emissions in logistics
We carry out logistics kaizen activities as part of our daily administrative tasks, and work together with plants to promote CO2 reductions by way of responding flexibly to daily changes in production. Within Japan, we are planning future expansion of joint logistics, as well as an associated reorganization of logistics transfer points, and are proceeding with both logistics optimization and further reductions in CO2 emissions.
In line with this work across Japan, we are also continuing to carry out change globally via implementation of logistics kaizen, and CO2 reduction activities across the world.
In the future we will actively investigate and consider the use of vehicles such as FCEV (fuel cell vehicles) and BEV (battery electric vehicles), as well as industrial machinery that does not rely on fossil fuels, and contribute towards realizing a carbon neutral future.
