Investment in environmental preservation and safety modification
Breakdown of investment
FY 2018 environmental investment
FY 2018 safety investment
We classify the cost of our measures for environmental protection in accordance with cost classification standards promulgated by the Ministry of the Environment.
Environmental accounting by fiscal year
- *Japan Environmental Policy Index, developed by teams under the leadership of Professor Nobuyuki Miyazaki 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 determined by dividing an economic indicator, in our case consolidated net sales, by total EIP.
Eight aspects of environmental impact (including chemical releases, greenhouse gas emissions, landfill wastes, and COD load) are evaluated. A new accounting policy is applied to net sales from fiscal 2011.
Greenhouse gas emissions in Japan by fiscal year
- *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 FY2013.
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
FY2018 greenhouse gas emissions in Japan by company
Scope 3 emissions by fiscal year*
- *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.
CO2 emissions from product shipment
- *Hybrid-electric vehicles, low-emission vehicles, fuel-efficient vehicles, and all-electric vehicles.
Pollution and Natural Resources / Water Resource Preservation
Treatment and disposal of industrial waste* by company
- *Not including waste generated from non-recurring events such as dismantling closed plants or waste generated from dismantling old homes when constructing new homes.
FY2018 off-site final disposal by category of waste*
* Excluding waste generated at the construction sites of Asahi Kasei Homes.
Final disposal of industrial waste generated at construction sites of Asahi Kasei Homes
ALC trimmings recycled by Asahi Kasei Construction Materials
Release and transfer of PRTR-specified substances by fiscal year
- *Volatile organic compound. Although the term generally applies to any organic compound which is in gaseous state at the time of release, regulations for the control of their release exclude methane and some fluorocarbons which do not form oxidants.
FY2018 release and transfer of PRTR-specified substances
- *Substances listed are those of which total release was 5 tons or more.
- *Amounts are rounded to the nearest ton.
Release of air and water pollutants by fiscal year
FY2018 release of air and water pollutants by site
- *1Sulfur oxides are formed when crude oil, fuel oil, or coal containing sulfur are used as fuel, or when industrial wastes containing sulfur are incinerated. Sulfur dioxide (SO2) is most common, but some sulfur trioxide (SO3) also forms. The term SOx is inclusive of both of these.
- *2Nitrogen oxides are formed in nature and during combustion at thermal power plants, factory boilers, internal combustion engines, and incinerators. The term NOx is inclusive of both nitric oxide (NO) and nitrogen dioxide (NO2).
- *3Soot and dust are fine particles formed in the combustion of fuel and other materials.
- *4COD (chemical oxygen demand) is an indicator of water pollution by organic substances, expressed in terms of the amount of oxygen required by an oxidizer to chemically oxidize the organic substances contained in the water.
