Development and Production Activities for the Realisation of a Low-Carbon Society

The Toyota Boshoku group works to reduce CO2 emissions in all areas, from development and design to production and logistics, in order to help prevent global warming.

Development and design

Reduce CO2 emissions in the life cycle of Toyota Boshoku products by reducing weights

Toyota Boshoku ascertains CO2 emissions in the life cycle of core products, from their manufacture and sale to utilisation and disposal, and then takes action to reduce these emissions as a means to promote more environmentally friendly products.

As part of these efforts, we are working hard to reduce the weight and size of products since CO2 during the utilisation period accounts for the majority of total emissions, and these initiatives are contributing to an increase in fuel efficiency and a reduction in CO2 emissions in automobiles.

Production and logistics

Reduce CO2 emissions in production

The Toyota Boshoku group is conducting energy-saving activities on an ongoing basis, centred on the Energy Conservation Session. In particular, energy conservation diagnostic activities are being implemented group-wide and we have implemented initiatives through to completion for the energy conservation items that we have extracted.

As a result, the Toyota Boshoku group achieved all of our targets for fiscal 2015. Specifically, we realised the Toyota Boshoku group target of 15.0t-CO2 / 100 million yen with a result of 13.2t-CO2 / 100 million yen; our target of 61,408t-CO2 in total Toyota Boshoku emissions with a result of 53,801t-CO2; and our target of 9.5t-CO2 / 100 million yen with a result of 7.8t-CO2 / 100 million yen.

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 2016 have been assured by KPMG AZSA Sustainability Co., Ltd. Please refer to their Independent Assurance Report, which appears on page 60 of Toyota Boshoku Report 2016, for more details.

Calculation of greenhouse gas emissions

The CO2 conversion coefficient has been fixed so that voluntary improvements can be evaluated. Japanese group companies use the values provided in the following table, while group companies globally use values issued in each region in 2001. The amount of CO2 reduced via co-generation is calculated using the average for thermal power, with the results reflecting emission amounts.

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
Light oil 2.64t-CO2/kL

[SCOPE 3 (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.

Reducing CO2 emissions in logistics

Toyota Boshoku regularly held logistics promotion meetings and worked to vitalise logistics-related activities at each plant. We implemented activities to enhance load efficiency through mixed loads and shifted to the appropriate vehicle class depending on the load amount. We also shared cases of improvement through continued participation in Toyota Group logistics and environmental liaison meetings.

As a result, Toyota Boshoku achieved its target of 4,978t-CO2 with a result of 4,305t-CO2 and Japan affiliates achieved their target of 3,387t-CO2 with a result of 3,164t-CO2.

Reducing CO2 emissions in logistics (Japan region)

The scope of CO2 management was expanded in fiscal 2010.

TOPICSActivities of the Energy Conservation Session

Toyota Boshoku’s Energy Conservation Session is carrying out energy conservation diagnostic activities globally. This involves extracting and analysing items in which energy can be saved and then focusing on key items among those that can be implemented immediately with zero investment. We are decisively carrying out initiatives related to these areas.

TOPICSEnergy conservation activities for air compressors

Toyota Boshoku Haiphong (Vietnam) has introduced equipment that enables control of air compressors, which account for a large portion of power consumption at the company, to realise optimum operation across the board. In addition, flow meters have been installed in each item of production equipment to identify and manage the amount of air required. As a result, this has helped optimise the operation of air compressors, thereby reducing CO2 emissions and energy costs.

  • Amount of CO2 reduced over the year: 1,399t-CO2
  • Amount of energy costs reduced over the year: 23,415 thousand yen
