Greenhouse gas emissions in Japan by fiscal year

(million tons CO₂ equivalent)

• 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 FY2020 onwards. The impact of this change on CO₂ emissions is immaterial.

Overseas greenhouse gas emissions by fiscal year

	2017	2018	2019	2020	2021
CO2 emissions	1.03	1.03	1.08	1.00	1.16

• Note
  
• ・Calculation standards for overseas 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. Until FY2020, 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 Emissions Factors, but in order to calculate GHG emissions that more reflect factual circumstances, we applied emission factors with the following priority order: 1) emission factors of individual power companies, 2) values set by national governments, and 3) International Energy Agency's Emissions Factors from FY2021.

Total	3.77	0.10	0.16	0.00	4.03

Scope 3 emissions by fiscal year

(million tons CO₂ equivalent)

• 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 FY2019.
  Since FY2020, 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 goods 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 raw materials 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 FY2021, the activity volume was changed from final disposal volume to effluent volume.
• ・ Calculation method for use of sold products:
  Until FY2020, the calculation was based on the calculation standards set by Asahi Kasei Homes and using the emissions intensity of 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 FY2020, based on the number of houses delivered; in FY2020, 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.

  In FY2021, the following calculations were made using 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 FY2021 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.
• Note: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）
