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 new accounting policy is applied to net sales from fiscal 2011.
|Total environmental impact (million EIP)||50,723||13,219||11,271||11,524||9,770||10,562|
|Net sales (¥ million)||1,195,393||1,940,914||1,882,991||2,042,216||2,170,403||2,151,646|
Greenhouse gas emissions in Japan by fiscal year
(million tons CO2 equivalent)
|Item||Index set at Kyoto Protocol
- 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.
Overseas greenhouse gas emissions by fiscal year*
(million tons CO2 equivalent)
- 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. 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.
- *Emissions of special core operating companies are included.

|End-of-life treatment of sold products||2.24||1.93||4.84||4.98||4.80|
- Calculation method for Scope 3:
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:
Up to fiscal 2015, emissions were calculated by multiplying the amounts, either in physical or monetary units, of the largest 20 raw materials and services (30 items 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.
From fiscal 2016 onward, 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 use of sold products:
Based on the calculation standards set by Asahi Kasei Homes, emissions are calculated after deducting the CO2 emission reduction effects, etc., based on the energy-saving equipment actually installed, which differs in each case, in the Hebel Haus (detached house/apartment building) units delivered each fiscal year (calculation period is set to 60 years).
- 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. Regarding past results, data up to fiscal 2016 that can be recalculated has been revised retroactively.
