Aiming to reduce life cycle CO2 emissions to zero

AISIN Group is working to reduce CO2 emissions from production and to reduce CO2 throughout the life of our products from design to transportation, use and disposal.

We are accelerating our development of products that help to improve fuel efficiency, such as electric drive units and parts such as brakes, chassis and bodies for electric vehicles and FCEVs.

We are also working to drastically reduce CO2 emissions throughout the production process, by carrying out activities to conserve energy within AISIN, compiling data on topics for innovation in production technology and adopting renewable energy.

Total CO2 emissions*1/index of CO2 emissions per sales (global)


Total CO2 emissions index of CO2 emissions per sales (global)
  • *1 CO2 emissions generated by energy from stationary sources.
  • *2 Target for FY2021: 20% reduction compared to FY2010
  • *3 The index used for CO2 emissions relative to revenue is calculated as a percentage of the figure for the baseline year (FY2010) of targets set out in the Sixth Aisin Consolidated Environmental Action Plan
  • *4 Figures for FY2020 and 2021 indicate the volume of CO2 emissions calculated based on the coefficients in the Sixth and Seventh Aisin Consolidated Environmental Action Plan respectively.
  • Note: The indexes of CO2 emissions per sales are calculated based on CO2 emissions within the scope set in the Sixth Aisin Consolidated Environmental Action Plan, while the scope of total CO2 emissions has included the scope of this plan and newly added manufacturing subsidiaries since FY2019.

■ Calculation method

Total CO2 emissions = Σ (fuel consumption × CO2 emission factor) + Σ (purchased electricity consumption × CO2 emission factor)

To reduce CO2 emissions, Aisin Kiko is working to reduce its electricity consumption by improving its methods to minimize the number of air compressors that are needed to power the production processes in its plant.

The decrease in production volume as a result of COVID-19 has halved the volume of air that is needed in Aisin Kiko’s plant operations. We reduced the unloaders that are used during breaks to save energy and after breaks in cases of increases in air intake, and achieved a reduction of electricity usage. As a result, we reduced electricity consumption by 9,800 kWh per month and CO2 emissions by 4.0 ton- CO2 per month.

Disclosure according to the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD)

AISIN Group agreed to TCFD recommendations in November 2019 in recognition of the significant link between our business activities and the environment. We have since carried out climate change scenario analysis according to TCFD* recommendations.

We will continue to analyze scenarios of the risks and opportunities presented by climate change and expand the scope of our disclosures to contribute to the development of a sustainable society.

TCFD:A task force on climate-related financial disclosures established in 2015 by the Financial Stability Board, an international organization that works to ensure the stability of financial systems.
