[3] Calculation method for environmental performance indices
Environmental Reporting Guidelines (2007 Version) published by the Japanese Ministry of the Environment were used as references.
Environmental performance indices Unit Calculation method
INPUT Energy consumption TJ Electricity purchased annually (kWh) x units of heat used *1
+ Σ [ Annual consumption of each fuel x heat value per unit *2 ]
*1: 9.76MJ/kWh based on regulations of the Law Concerning the Rational Use of Energy (enforced April 1, 2006)
*2: Based on the heat value per unit per energy source used by the Agency for Natural Resources and Energy (February 2002) - City gas (13A): 41.1GJ/km3, City gas (7C): 18.5GJ/km3, LPG: 50.2GJ/t, Fuel oil: 39.1GJ/kl, Kerosene: 36.7GJ/kl, Light oil: 38.2GJ/kl, Gasoline: 34.6GJ/kl, Steam: 2.926GJ/t
Electricity purchased million KWh Electricity purchased annually
City gas purchased 1,000 m3 City gas purchased annually
LPG purchased t LPG purchased annually
Fuel oil, kerosene, light oil, and gasoline purchased kl Fuel oil purchased annually
PFCs purchased 10,000
GWPt-CO2
PFCs purchased annually
Chemical substances handled t Among the substances covered under the Law Concerning Reporting, etc. of Releases to the Environment of Specific Chemical Substances and Promoting Improvements in Their Management (PRTR Law), the total amount of substances handled in quantities greater than 500 kg annually at each production site.
Water consumed 1,000m3 Annual consumption of water supply, well water, and water for industrial use
Packaging materials t Packaging materials consumed annually
Resources consumed 10,000 tons Total weight of products in the 13 major categories shipped in fiscal 2007 (estimate) and waste , etc generated from production sites
Logistics Energy consumption GJ Revised ton-km system
Use of products Energy consumption TJ(million KWh) Energy consumption of products in the 12 major categories shipped in fiscal 2007 was calculated based on electricity consumed by each product
Recycling Home appliances
(four kinds)
t Amount of used home appliances (four kinds) recycled into new home appliances
Copiers Amount of recycled copiers
PCs Amount of recycled PCs
Amount of closed-loop material recycling of plastics Amount of closed-loop material recycling of plastics
OUTPUT CO2 emissions 10,000 t-CO2 Σ [Electricity purchased annually x CO2 emission coefficient * + annual consumption of each fuel x CO2 emission coefficient for each *]
* : <Electricity>
Japan
Based on the values officially announced by the Federation of Electric Power Companies of Japan
Fiscal 2006: 0.410 (t-CO2/MWh) / fisical 2005: 0.423 (t-CO2/MWh) / fiscal 2004: 0.418 (t-CO2/MWh) / fiscal 2003: 0.433 (t-CO2/MWh)
Overseas
Using the fiscal 2003 coefficient of each country from the Report on the CO2 Emissions Intensity of the Power Sector of Various Countries that was compiled by the Japan Electrical Manufacturers' Association (June 2006)
<Other>
Based on the values officially announced in the Guidelines for Calculation Method of Greenhouse Gas Emissions published by the Ministry of the Environment
City gas (13A): 2.080 (t-CO2/km3), City gas (7C): 0.796 (t-CO2/km3), LPG: 3.000 (t-CO2/t), Heavy oil: 2.710 (t-CO2/kl), Kerosene: 2.489 (t-CO2/kl),Gasoline: 2.322 (t-CO2/kl) ,Light oil: 2.619 (t-CO2/kl)
PFC emissions GWPt-CO2 Σ [Annual emissions of each PFC gas x global warming potential of each PFC gas *]
* Based on the IPCC's Third Assessment Report
Sulfur hexafluoride: 22,200. The coefficient corresponding to segmentalized gas are used for HFC and PFC.
SOx emissions t SOx emissions per hour (Nm3/h) x annual operation hours of facility (h) x (64kg - SO2/22.4m3N) x 10-3
NOx emissions t NOx emissions per hour (Nm3/h) x annual operation hours of facility (h) x (46kg - NO2/22.4m3N) x 10-3
Drainage 1,000m3 Annual drainage into public body of water and sewer system
Chemical oxygen demand t COD concentration (mg/l) x drainage into public body of water (m3) x 10-6
Nitrogen emissions t Nitrogen concentration (mg/l) x drainage into public body of water (m3) x 10-6
Phosphorus discharged t Phosphorus concentration (mg/l) x drainage into public body of water (m3) x 10-6
Waste discharged t Industrial waste discharged + general waste discharged from business activities
Waste, etc. discharged t Industrial waste discharged + general waste discharged from business activities + amount of valuable resources
Final landfill disposal t Final landfill disposal of industrial waste + final landfill disposal of general waste discharged from business activities
Chemical substances (PRTR) released and transferred t Appropriate management of specific chemical substances released and transferred covered by the PRTR Law, handled in quantities greater than 500 kg in a year at each produetion site
