Eco-efficiency (JEPIX*) performance

  • *JEPIX is an abbreviation for the "Japan Environmental Policy Index", and it was developed by teams under the leadership of Professor Nobuyuki Miyazaki of the International Christian University at the Japan Science and Technology Agency and Sustainable Management Forum Japan. Environmental performance data are converted to an environmental impact point (EIP) scale and aggregated to determine total environmental impact.
    Eco-efficiency is calculated as follows.
    Eco-efficiency = value added (economic index) / JEPIX Eco-Points
    Eight aspects of environmental impact (including chemical releases, greenhouse gas emissions, landfill wastes, and COD load) are evaluated, and net sales are used for value added. A revised accounting policy is applied to net sales from fiscal 2011.

  • Notes
  • Calculation standards for greenhouse gas emissions:
    For greenhouse gases covered by the Act on Rationalizing Energy Use and the Act on Promotion of Global Warming Countermeasures, calculations are in accordance with the methods stipulated by these laws. For gases not covered by either law, calculation methods are based on considerations such as chemical reactions.
  • CO2 emissions from generation of electricity and steam sold to other companies are excluded from data for the baseline year but included in annual data from fiscal 2013.
  • We have used 'basic' CO2 emission factors for electricity purchased in Japan until FY2019, but we have opted to use 'adjustedʼCO2 emission factors from fiscal 2020 onwards. The impact of this change on CO2 emissions is minor.

  • Note
  • Calculation standards for greenhouse gas emissions:
    Overseas greenhouse gas emissions are calculated, in principle, based on the provisions given by the Act on the Rational Use of Energy and the Act on Promotion of Global Warming Countermeasures, and CO2 emissions from the burning of by-product gases are mainly calculated by material balance. Until fiscal 2020, CO2 emissions associated with purchased electricity were calculated using the latest country-specific emission factors shown in the International Energy Agency's (IEA) Emissions Factors. However, from fiscal 2021, in order to aggregate GHG emissions with values closer to actual situations, we have calculated emissions with the available emission factors in the following order of priority: 1) emission factors of procurement sources, 2) values set by national governments, and 3) IEA country-specific emission factors.

  • Notes
  • Calculation method for Scope 3:
    Our Scope 3 GHG emissions are calculated using the Corporate Value Chain (Scope 3) Accounting and Reporting Standard and its technical guidance issued by the Greenhouse Gas Protocol. For the greenhouse gas emission factors, we used data available in the Carbon Footprint Communication Program database prepared by the Japan Environmental Management Association for Industry and the Embodied Energy and Emission Intensity Data for Japan Using Input-Output Tables (3EID): Inventory Data for LCA prepared by the National Institute for Environmental Studies, Japan until fiscal 2019.
    Since fiscal 2020, we have referred to the Embodied Energy and Emission Intensity Data for Japan Using Input-Output Tables (3EID) (2015): Inventory Data for LCA prepared by the National Institute for Environmental Studies, Japan, IDEA v2.3 by the National Institute of Advanced Industrial Science and Technology, and the Emissions Unit Value Database Ver3.2 for Accounting of Greenhouse Gas Emissions, etc., by Organizations Throughout the Supply Chain issued by the Ministry of the Environment, etc.
  • Calculation method for purchased products and services:
    Items with emissions equal to or greater than 4,000 tons of CO2-equivalent were included. The emissions were calculated by multiplying the amounts, either in physical or monetary units, of products and services purchased from outside the Asahi Kasei Group by Asahi Kasei Corp., Asahi Kasei Homes, Asahi Kasei Construction Materials, Asahi Kasei Microdevices, and Asahi Kasei Medical by the respective emission factor for each type of raw material or service.
  • Calculation method for waste generated in operations:
    From fiscal 2021, the activity volume was changed from final disposal volume to effluent volume.
  • Calculation method for use of sold products:

    Until fiscal 2020, the calculation was based on the calculation standards set by Asahi Kasei Homes and using the emissions intensity from Housing Tech. R&D Labs’ report. The period covered by the calculation was calculated based on the number of Hebel houses (detached houses and apartment buildings) delivered in each fiscal year (before fiscal 2020, based on the number of houses delivered; in fiscal 2020, based on the total floor area of Hebel houses delivered). The calculation period was set to 60 years of useful life, and the CO2 emissions reduction effect based on the actual installation of energy-saving equipment, which differs in each case, was deducted from the calculation.

    From fiscal 2021, the following calculations were made using the Building Research Institute's "Energy Consumption Performance Calculation Program (Residential Version)" for house for which a certificate of confirmation was issued during the fiscal year.

    ∑ (annual energy use by energy type per household x emission factor by energy type) x useful life (60 years)

    Emission factor by energy type

    Emission factor
    Electricity 0.453 (t-CO2/thousand kWh), City gas 0.05 (t-CO2/GJ), Kerosene 0.068 (t-CO2/GJ)

    If calculated using the conventional method, Category 11 emissions in fiscal 2021 would be 1.37 million tons CO2-eq.

  • Calculation method for disposal of sold products:
    For Asahi Kasei, Asahi Kasei Construction Materials, and Asahi Kasei Medical, emissions are calculated by multiplying the weight of products shipped each fiscal year by the CO2 emission factor at the time of disposal for each product.
    For Asahi Kasei Homes, emissions are calculated by multiplying the number of Hebel Haus units delivered each fiscal year by the CO2 emission factor per building.
  • In fiscal 2018, we revised some of the calculation methods for upstream transportation/distribution and disposal of sold products so that they are based on the actual situation. Past results have been adjusted retroactively.
  • Past results have been revised due to an error in the quantity of purchased goods and services in FY2020. Emissions before correction are as follows:
    (Category 1: 4.53 million tons CO2-eq, Category 4: 0.24 million tons CO2-eq, Category 12: 5.68 million tons CO2-eq, Total 12.99 million tons CO2-eq)

  • 1 Sulfur oxides (SOx) are formed when crude oil, fuel oil, or coal containing sulfur are used as fuel. Sulfur dioxide (SO2) is most common, but some sulfur trioxide (SO3) also forms. The term SOx is inclusive of both of these.
