Primarily, this report covers data acquired from April 2019 to the end of March 2020, with a portion of information that involves data acquired after April 2020.
|GHG Energy||Energy||Energy = (fuel, electric energy, etc.) x energy conversion factor
|GHG||Energy originated CO2 = (fuel quantity, electricity quantity) x CO2 emission factor
Non-energy originated GHG = Gas emissions x Global warming potential (GWP)
|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
|Market-based Scope 2||CO2 emission = purchased electricity quantity x CO2 emission factor
|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|
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|
