Abstract
We have calculated a emission of GHG through the supply chain according to basic guidelines for the GHG emission calculation through the supply chain (Ministry of the Environment/Ministry of Economy, Trade and Industry). The total GHG emissions through our company's supply chain was 1,832,000 t-CO2. The breakdown is as follow, the scope 1 emission was 663,000 t-CO2, the scope 2 emission was 152,000 t-CO2, and the scope 3 emission was 663,000 t-CO2. It is revealed that the scope 3 emission was more than the company's total scope 1 and 2 emission. Furthermore, emissions of the GHG from a product, the service that we purchased occupied 35 % of the emissions through the supply chain, and it became clear to be a main GHG emission source in the supply chain more.
