Calculation base of typical environmental data

Classification Item Calculation Method
GHG Energy Energy Energy = (fuel, electric energy, etc.) x energy conversion factor
  • Fuels (other than biomass), conversion coefficient of electric power: standard heating value of the Agency for Natural Resources and Energy (2013 value)
  • Biomass fuel: National Woodchips Industry Association (Japan)
  • Regional heat: site reported value (1.54 GJ / MWh)
  • Steam: Site report value (2.571 GJ / t)
GHG Energy originated CO2 = (fuel quantity, electricity quantity) x CO2 emission factor
Non-energy originated GHG = Gas emissions x Global warming potential (GWP)
  • CO2emission factor
    Electricity: 2010 value of IEA CO2 EMISSIONS FROM FUEL COMBUSTION 2012
    Fuel: Japan,Overseas;Ministry of the Environment, Ministry of Economy, Trade and Industry,　Greenhouse gas emissions calculation and report manual
  • GWP: Value of greenhouse gas emissions calculation, reporting and publication system
Energy, CO2 emission in basic unit Basic unit for each plant = (energy, CO2) / (Internal manufacturing value), index is a value with base year 100.
Base year: 2010
Location-based Scope 2 CO2 emission = purchased electricity quantity x CO2 emission factor
  • CO2 emission factor:
    Japan; Ministry of the Environment, Ministry of Economy, Trade and Industry Emission Factor by Electric Utility Substitution Value
    Overseas; 2010 value of IEA CO2 EMISSIONS FROM FUEL COMBUSTION 2012
Market-based Scope 2 CO2 emission = purchased electricity quantity x CO2 emission factor
  • CO2 emission factor:
    Japan;Emission Factor by Electric Power Company
    Overseas; 2010 value of IEA CO2 EMISSIONS FROM FUEL COMBUSTION 2012
    However, the electricity generated from renewable energy source has zero emission factors
Scope3 C1 Purchased product service: Product weight x emission factor + cooperating company CO2 emission amounts + Purchased packaging material weight x emission factor
C2 Capital goods: capital investment amount x emission factor
C3 Fuels and energy related activities not included in Scope 1 and 2: fuel quantity purchased x emission factor on the upstream side + purchased electric energy amount x upstream side emission factor
C4 Transportation, Delivery (upstream): Fuel consumption (amount) x Emission factor (coefficient according to Komatsu actual result survey)
C5 Waste from project: Waste volume x Emission factor (coefficient according to Komatsu performance survey)
C6 Business trip: travel expenses x emission factor
C7 Employer commuting: commuting expenses x emission factor
C9 Downstream transport: transport volume x emission factor
C11 Use of products sold: Σ (Production volume per product model x Fuel consumption x Product life)
C12 Disposal of products sold: Product weight x Emission factor
  Emission factor
Power of C1/C2/C3, C6/C7/C12: Emission basic unit database (Ver 3.0) for calculating greenhouse gas emissions of organizations through the supply chain of the Ministry of the Environment
C3 Fuel: Carbon Footprint Communication Program Basic Database (Ver 1.01)
C9: Ministry of Economy, Trade and Industry ・ Ministry of Land, Infrastructure, Transport and Tourism Guidelines for Estimating CO2 Emissions in the Logistics Field
Exhaust Sox Emissions Total for heavy oil, kerosene, light oil and coke:
Calculated from fuel quantity x sulfur content in fuel
NOx Emissions Total for heavy oil, kerosene, light oil, city gas, and LPG:
Calculated from Exhaust gas quantity x NOx concentration
Drainage BOD Emissions Calculated from Wastewater x BOD Average Concentration Measurement Value
COD Emissions Calculated from Wastewater x COD average concentration measured value
