Environmental Accounting

We classify the cost of our measures for environmental protection in accordance with cost classification standards promulgated by the Ministry of the Environment.

Overseas greenhouse gas emissions by fiscal year
  • Calculation standards for overseas GHG emissions:
    Overseas GHG 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. CO2 emissions from the burning of by-product gases are mainly calculated by material balance. CO2 emissions associated with purchased electricity are calculated with the latest available coefficients given in International Energy Agency's CO2 Emissions from Fuel Combustion.
  • Including emissions of special core operating companies

  • Referenced guidelines:
    Our Scope 3 GHG emissions are calculated in accordance with 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 use 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.
  • Including overseas subsidiaries from fiscal 2017
  • Calculation method for purchased goods and services:
    For fiscal years from 2014 to 2015, emissions were calculated by multiplying the amounts, either in physical or monetary units, of the largest 20 raw materials and services (30 in the case of Asahi Kasei Chemicals), in terms of GHG emissions or purchase amount, purchased from outside the Asahi Kasei Group by Asahi Kasei Chemicals, Asahi Kasei Fibers, Asahi Kasei Homes, Asahi Kasei Construction Materials, Asahi Kasei Microdevices, Asahi Kasei E-materials, and Asahi Kasei Medical, by the respective emission factor for each type of raw material or service. For fiscal year 2016 onward, items with emissions equal to or greater than 4,000 tons of CO2-eq were included. The emissions were calculated by multiplying the amounts, either in physical or monetary units, of raw materials and services purchased from outside the Asahi Kasei Group by Asahi Kasei Corp., Asahi Kasei Homes, Asahi Kasei Construction Materials, Asahi Kasei Mircodevices, and Asahi Kasei Medical, by the respective emission factor for each type of raw material or service.
  • Calculation method for use of sold products:
    Emissions were calculated for Hebel Haus homes (unit homes and multi-dwelling homes) delivered each fiscal year based on a formula set by Asahi Kasei Homes, with a service life of 60 years as the period subject to calculation, and the effect of emissions reduction calculated based on the different energy conservation equipment actually installed in each case.
  • Calculation method for end-of-life treatment of sold products:
    Emissions for Asahi Kasei Corp., Asahi Kasei Construction Materials, and Asahi Kasei Medical were calculated by multiplying the weight of products shipped each fiscal year by the respective emission factor for end-of-life treatment of each product. For Asahi Kasei Homes, emissions were calculated by multiplying the number of Hebel Haus buildings delivered each fiscal year by the emission factor.
  • From fiscal 2018, the calculation methods for upstream transportation and distribution and for end-of-life treatment of sold products were partially revised to conform to the actual situation. Previous results were recalculated to the extent possible, and figures were revised retroactively to fiscal 2016.
