Development of Land Use Area Intensity Database Using Asia International Input-output Table for Life Cycle Assessment

Abstract

As corporate activities are needed for biodiversity conservation, a number of companies have started to understand the relationship between their supply chain and biodiversity. Life cycle assessment (LCA) has been required to apply to assess impacts on biodiversity and ecosystem throughout life cycle of a product. However, most of LCA case studies focus on global warming such as carbon footprinting, a number of studies assessed an impact on biodiversity is still limited. Land use is considered as key inventory item to promote biodiversity assessment in LCA. This study therefore aimed at the development of land use inventory database using input-output analysis. This study estimated occupied land area caused by a certain amount of production activities, and to verify the adequacy of this study, an estimation of total land use area induced by final consumption was carried out.
