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 technology, the technological development of products and materials, the improvement of plants and the utilisation of renewable / next generation energy.

Toward zero CO2 emissions

Toyota Boshoku has set a 2020 target of reducing CO2 emissions by 10% compared with 2015 as a stepping stone toward realising zero CO2 emissions by 2050, and is pushing ahead with activities to make this a reality. Efforts focus on developing new technologies in consideration of efficient use of energy from the development and design stage, which includes using new technologies, methods and materials development in addition to daily kaizen at plants in such areas as energy conservation. Besides this, we are making fundamental reforms that go beyond previous domains of improvement, such as the use of fuel cells, hydrogen and other forms of renewable energy. We are also preparing scenarios to reduce CO2 by 2030 that focus on both the medium and long term in addition to our 2020 target. This target also will be deployed to respective business entities going forward. Giving shape to plans such as this helps to strengthen activities to reduce CO2 on a group-wide basis.

Energy consumption and CO2 emissions and basic unit of Toyota Boshoku and those of the Toyota Boshoku group released on our website have been independently assured by KPMG AZSA Sustainability Co., Ltd. Please see the Independent Assurance Report for more detailed information.

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 2014.

CO2 conversion coefficient
Fuel CO2 conversion coefficient
Purchased electricity 0.37t-CO2/MWh
City gas 2.16t-CO2/thousand m3
LPG 3.00t-CO2/t
Kerosene 2.53t-CO2/kL
Heavy oil 2.70t-CO2/kL
Diesel oil 2.64t-CO2/kL

[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 2013.

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.
