Aiming to reduce life cycle CO2 emissions to zero

AISIN Group is drawing on its cohesive strength as a group 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 and fuel cell vehicles.

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)
  • CO2 emissions of energy consumption from stationary combustion sources.
  • The index used for emissions per sales is calculated as a percentage of the figure for the baseline year (FY2010) of targets set out in the Sixth Environmental Action Plan.
  • Target for FY2021: 20% reduction compared to FY2010

Note: The indices for fiscal year 2018 and 2019 have been corrected.

■ Calculation method

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

CO2 emission factors

Japan Fuel Emission factor set in accordance with the Act on Promotion of Global Warming Countermeasures
Purchased electricity Emission factor set in accordance with the Federation of Electric Power Companies of Japan 2009 (Environmental Action Plan for Electricity Businesses 2013)
Overseas Fuel Emission factor set in accordance with the Act on Promotion of Global Warming Countermeasures
Purchased electricity Emission factor set in accordance with IEA 2009 (CO2 Emissions from Fuel Combustion 2013 Edition)

■ Scope of calculation

Aisin Seiki Co., Ltd. and 128 main consolidated manufacturing subsidiaries

AISIN Group is working on biomass* power generation to help to build a society that is both low carbon and recyclingoriented. Yamagata Clutch Co., Ltd. introduced AISIN Group’s first electricity generated by biomass in July 2020, achieving an annual emission reduction of around 300t-CO2.

We are now working to expand the use of biomass-based electricity throughout AISIN Group and use more renewable energy in future to build a sustainable society.

*Biomass is a general term for biological materials from sources such as flora and fauna. When electricity is generated from biomass, these materials are converted to energy through processes such as direct combustion or gasification. Technology development in this area is advancing, with various forms of biomass used effectively.

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.
