GHG Net-zero in the plant*
Basic approach
In pursuit of the GHG Net-zero in the plant, as described in our 2050 Environmental Vision, we are promoting various environmental activities with the aim of reducing CO2 emissions by 50% by the year 2030 (compared to FY2020 levels), and reducing CO2 emissions by 100% by the year 2035.
- achieving net zero greenhouse gas emissions
Efforts to Achieve Carbon Neutrality
1. Promotion of initiatives to ensure completion of Toyota Boshoku’s 40 initiatives for energy conservation
Energy conservation is important to Toyota Boshoku, with many energy saving initiatives being discussed, shared, and carried out across all areas of our business. However, when looking at the situation on the ground, it’s clear that more still needs to be done in certain areas.
To address this, we have selected 40 specific energy conservation initiatives to be prioritized globally. These initiatives can be divided into two categories: E-JIT* initiatives, which can be implemented through behavioral and workflow changes without additional financial cost, and equipment efficiency improvements, which involve either adoption of highly efficient equipment, or retrofitting of pre-existing facilities.
Additionally, we are working on developing and distributing both a manual for how to approach such improvements, and a mid-term activities plan to guide our future energy savings activities.
- E-JIT: Energy Just-In-Time (generating only the amount of energy that is required at that point in time to produce the necessary quantity of products)

2. Active introduction of renewable energy
The Toyota Boshoku group is proactively introducing renewable energy. Since October 2022, 100% of the electricity purchased in Japan from Chubu Electric Power has zero CO2 emissions. Additionally, from January 2023, electricity use at all European sites (excluding sites in Africa) has been successfully converted to 100% renewable energy.
Moving forward, our entire group will continue to systematically introduce renewable energy and respond to the need for carbon neutrality.

The size of avoided CO2 emissions through the introduction solar power generation equipment
- We calculate the size of avoided CO2 emissions by multiplying the PV power generation which we have introduced by the “CO2 conversion coefficient” of purchased electricity on the below.
Calculation of greenhouse gas emissions
CO2 conversion coefficients for electric power in Japan are calculated with reference to emissions coefficients from each domestic electric utility company (based on emissions survey results), and included in Electric Utility Companies’ Emissions Coefficients (for use in calculating greenhouse gas emissions of companies emitting above a certain set level)-Results from Fiscal 2022, published by Japan’s Ministry of the Environment, whereas for electric power in other regions they are calculated with reference to the IEA’s Emissions Factors 2022.
CO2 conversion coefficients for gas and other fuels are calculated with reference to A Summary of Calculation Methods and Emission Intensities for Systems of Calculating, Reporting and Publishing Environmental Data published by Japan’s Ministry of the Environment.
