Challenge of achieving zero CO2 emissions

Basic approach

The Toyota Boshoku group takes on the challenge of 'achieving zero CO2 emissions from all of our plants by 2050'. We will strive to reduce CO2 emissions significantly through the development of innovative production engineering, the technological development of products and materials, the improvement of plants and the utilisation of renewable / next generation energy.

Global deployment of the 2030 CO2 reduction scenarios

In order to achieve the 2030 target that we formulated in fiscal 2019, we visited two bases in the Americas, Asia & Oceania, China, and Europe & Africa regions. During these visits, we promoted the creation of CO2 reduction scenarios while cooperating with local members to examine improvement items which can or should be implemented globally. Going forward, the entire Toyota Boshoku group will promote activities for reducing CO2 emissions.

1 Daily improvements at plants
Mould ejection equipment with a conveyor using Karakuri mechanisms

At the Oguchi Plant, we made improvements by using Karakuri mechanisms to enable ejection of punch scraps from moulded ceiling trim dies. As a result, we reduced the amount of air used by 100%.

3 Renewable energy [environmental performance]
Active introduction of renewable energy

The Toyota Boshoku group has systematically introduced renewable energy. In fiscal 2020, we utilised the PPA*1 system to further accelerate the introduction of solar power generation.
Moving forward, the entire Toyota Boshoku group will continue to systematically introduce renewable energy and respond to climate change.

The size of contribution in reducing the amount of CO2 emission through the introduction of renewable energy

*2 We calculate the size of contribution in reducing the amount of CO2 emission 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

The CO2 conversion coefficients have been fixed so that voluntary improvements can be evaluated. Japanese group companies use the values provided in the following table, while the power coefficient for regions outside Japan is calculated using country data from 2000 released by the International Energy Agency (IEA) in 2013.*3

Greenhouse gas emissions reflect efforts to reduce CO2 through co-generation (calculated by multiplying the amount after deducting the CO2 emission factor for all power sources from the CO2 emission factor for thermal power generation by the amount of power generated through co-generation).

[SCOPE 3*4 (Supply Chain Management)]

Toyota Boshoku has commenced to calculate the CO2 emission of whole Toyota Boshoku's supply chain in order to reduce the CO2 emission from our whole business activities since FY2013.

Next, we will improve the precision of calculating method, and proceed to reduce CO2 emission after we evaluate the CO2 emission of each category in our whole business activities.

Reducing CO2 emissions in logistics

As part of our Logistic Session, we regularly convene logistics promotion meetings and through connection between plants and logistics companies work to reduce CO2 emissions in logistics and reduce pollution caused by vehicles used in distribution. In addition, the cross-organisational deployment of best practices from each plant aids in efforts to vitalise activities between plants.
Further, we continue to participate in Toyota Group logistics and environmental liaison meetings to share the latest information and information on best practices from other companies.
