As corporate activities are needed for biodiversity conservation, a number of　companies have started to understand the relationship between their supply chain and biodiversity.

Land use is considered as key inventory item to promote biodiversity assessment in LCA. This study aimed at the development of land use inventory database using input-output analysis.
