Calculation Standards for Environmental Performance Data
The environmental performance data are calculated based on the following calculation standards.
Input
Environmental Performance Indicators |
Calculation Method |
Procurement, R&D, product manufacture |
Energy consumed |
Calculated based on the Act on Rationalizing Energy Use and the Japanese Ministry of the Environment’s Greenhouse Gas Emission Calculation and Reporting Manual |
PFCs purchased |
HFCs, PFCs, sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3) purchased annually |
Water resources consumed |
Consumption and recycled use of water purchased from third parties (industrial-use water, tap water) and groundwater |
Chemical substances handled (PRTR-listed) |
Among the substances covered under the PRTR Law, the total amount of substances handled annually at each plant in quantities of 500 kg or more |
Chemical substances handled (VOCs) |
Among the 20 types of volatile organic compounds (VOCs) specified by Japan’s four major electrical and electronic industry associations, the total amount of substances handled annually at each plant in quantities of 1 metric ton or more |
Materials consumed |
Total weight of major products* sold in the reporting year (estimate), plus waste, etc. generated |
Logistics |
Energy consumed |
Revised ton-km method |
Product use |
Energy consumed |
Estimate of annual energy used by major products* sold in the reporting year. Calculation based on each product’s annual energy consumption rate (using a heat input per unit of 9.97 MJ/kWh). |
- * Flat-panel TVs, air conditioners, refrigerators/freezers, washing machines/dryers, air purifiers, Plasmacluster Ion generators, microwave ovens, copiers/MFPs, solar cells.
Output
Environmental Performance Indicators |
Calculation Method |
Procurement, R&D, product manufacture |
Greenhouse gas emissions |
- CO2 emissions from purchased electricity
Japan:
Using CO2 emission coefficient by electric power company (adjusted) published by Japan’s Ministry of the Environment and the Ministry of Economy, Trade, and Industry
Overseas:
Using emission coefficients published in the environmental reports, etc. of electric power companies, or emission coefficients published in the IEA Emissions Factors
- CO2 emissions from consumed fuel
Using emission coefficient published in the Ministry of the Environment’s Greenhouse Gas Emission Calculation and Reporting Manual
- Greenhouse gases other than CO2
Using global warming potential published in the 4th Assessment Report by the Intergovernmental Panel on Climate Change (IPCC)
|
Drainage |
Annual drainage into public water areas and sewer system |
Chemical substances released and transferred (PRTR-listed) |
Among the substances covered under the PRTR Law, the total amount of substances (handled annually at one or more plant in quantities of 500 kg or more) that were released and transferred |
Chemical substances released (VOCs) |
Among the 20 types of volatile organic compounds (VOCs) specified by Japan’s four major electrical and electronic industry associations, the total amount of substances (handled annually at each plant in quantities of 1 metric ton or more) that were released and transferred |
NOx emissions |
Annual emissions |
SOx emissions |
Annual emissions |
COD (chemical oxygen demand) |
Drainage into public water area |
Nitrogen pollutant load |
Drainage into public water areas |
Phosphorous pollutant load |
Drainage into public water area |
Product shipments |
Total weight of major products* sold in the reporting year, plus packaging material used (estimate) |
Waste, etc |
Industrial waste + general office waste + valuable resources recovered |
Final landfill disposal |
Final landfill disposal of industrial waste + final landfill disposal of general office waste |
Logistics |
CO2 emissions |
Revised ton-km method |
Product use |
CO2 emissions |
Amount of CO2 emitted by major products* sold in the reporting year, based on their energy consumption (estimate) |
- * Flat-panel TVs, air conditioners, refrigerators/freezers, washing machines/dryers, air purifiers, Plasmacluster Ion generators, microwave ovens, copiers/MFPs, solar cells.
Recycle
Environmental Performance Indicators |
Calculation Method |
Disposal, recycling |
Home appliances (4 kinds)* |
Amount of used home appliances (4 kinds) recycled |
Copiers/MFPs |
Amount of recycled copiers and MFPs |
PCs |
Amount of recycled PCs |
Amount of closed-loop material recycling of plastic |
Amount of recycled plastic used, which was produced through closed-loop material recycling |
Disposal after recycling |
[Weight of 4 kinds of home appliances, PCs, and copiers/MFPs collected] – [Weight recycled into new products or materials, or reused] |
- * TVs (CRT TVs, flat-panel TVs), air conditioners, refrigerators/freezers, washing machines/dryers.
