Scope 3

HCM Group has been calculating CO2 emissions over product lifecycle since FY 2007, and CO2 emissions over the entire supply chain, including Scope 3, since 2009. We receive third-party evaluation for GHG emissions based on criteria of verification ISO 14064-3 at limited level of assurance.

Scope Category Classification CO2 Emission
(t)
Total Scope Criterion, Method, Prerequisite, Other
Scope1 Direct Emission 107,857 All Domestic and Overseas Production/Non-production Bases for Consolidation Conversion Coefficient Source: CO2 conversion coefficient of the International Energy Agency (IEA) energy, 2010 edition
Scope2 Indirect emissions from energy generation (electrical power etc) 211,151 All Domestic and Overseas Production/Non-production Bases for Consolidation
Scope 3 (upstream) 1 Purchased Products/Services 1,963,116 The five main domestic and overseas product groups (Mini-excavators, Hydraulic excavators, Wheel loaders,
Rigid dump trucks, and compaction equipment)
(1) CO2 emissions volume from each product material (t-CO2)= Shipped product’s weight x CO2 emission coefficient from material
Weight per unit: The weight of main models in each model groups is applied
Reference for emission basic units: IDEA (Inventory Database for Environmental Analysis) developed and supplied by the National Institute of Advanced Industrial Science and Technology and the Japan Environmental Management Association for Industry
(2) CO2 emissions volume from purchased goods and services
Totals the CO2 emissions volume for each product based on (1) above

Energy/CO2 Reduction Heat Conversion from the Amount of Energy Reduction (GJ) Amount of CO2 Saving (t-CO2) Criterion, Method, Prerequisite, Other
Energy/CO2 Reduction from Products/Services 52,000,000 3,550,000 Conversion Coefficient Source: IEA, or the Public Works Quantity Survey Criterion from the Ministry of the Land, Infrastructure, Transport and Tourism Calculation Method: Amount of energy reduction = (amount of energy used by reference product – amount of energy used by developed products) x no. of products sold x contribution rate
Reference model: FY 2005 Products and Services
CO2 emissions from biological sources 72.38 4.95 Fuel containing BDF (Bio Diesel Fuel) is used in the forklifts. Reference for conversion coefficient: Revised Energy Conservation Law; Calculation Method: Revised Energy Conservation Law
