Establishment of Low-Carbon Society (Climate Change, CO2)
The Toyota Boshoku group works to combat climate change in all areas, from development and design to production and logistics, in order to help create a low-carbon society and prevent global warming.
Production and Logistics
Reducing CO2 emissions in production
Toyota Boshoku has been pushing ahead with activities to conserve energy. These include initiatives that enable improvements immediately upon completion with zero investment, deemed priority actions by our Energy Conservation Session, as well as thoroughly implementing Energy-Just-in-Time (E-JIT) activities and examining energy conservation investments in consideration of future changes in production volume.
As a result, the Toyota Boshoku group achieved all of our targets for fiscal 2016. Specifically, we realised the Toyota Boshoku target of 62,280t-CO2 with a result of 57,143t-CO2, the Toyota Boshoku target of 19.1t-CO2 per 1,000 units with a result of 18.1t-CO2, and the Toyota Boshoku group target of 36.0t-CO2 per 1,000 units with a result of 35.5t-CO2.
The total amount of CO2 emissions and basic unit of Toyota Boshoku and those of the Toyota Boshoku group that are reported in Toyota Boshoku Report 2017 have been assured by KPMG AZSA Sustainability Co., Ltd. Please refer to their Independent Assurance Report, which appears on page 70 of Toyota Boshoku Report 2017, for more details.
*1 The Toyota Boshoku group shifted to using production volume instead of sales, which are susceptible to external factors, for the basic unit so that improvements are more accurately measured.
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.
|Fuel||CO2 conversion coefficient|
|City gas||2.16t-CO2/thousand m3|
[SCOPE 3*2 (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 2012.
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.
On the below, CO2 emission from representative cars' door trims, which are calculated with reference the guideline from Ministry of the Environment and Ministry of Economy, Trade and Industry.

CO2 in both upstream and downstream in business
【Upstream】 CO2 by supply of material, transportation and employees' transfer
【Downstream】CO2 by using and end-of-life treatment of sold products

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.
As a result, Toyota Boshoku achieved its target of 8,018t-CO2 with a result of 6,593t-CO2 and Japan affiliates achieved their voluntary target of 3,573t-CO2 with a result of 3,071t-CO2.
