Abstract

Supply chains have been configured globally among not only developed but also developing countries including Asia. For an anti-global warming, it is necessary for assembly manufacturers in the supply chains to visualize and reduce Greenhouse Gas (GHG) emissions by selecting suppliers for each part in across countries as a low-carbon supply chain. Each part has a different procurement cost by the suppliers while their GHG emissions for each part production depend on each country produced. Therefore, a Life Cycle Inventory (LCI)database has been developed by the Asian international input-output (I/O) table in order to calculate an environmental impact for each Asian country. This study proposes a low-carbon supplier selection method so as aiming to achieve both the procurement cost minimization and the environment impact reduction using the LCI database by the Asian international I/O table.
