Popis: The objectives of this study are to develop life cycle impact assessment (LCIA) methods that enable an assessment of the impact on the biodiversity by land use categorized in general land use types and to obtain the implications for an assessment of global land use impact, using the methods in the Life Cycle Impact Assessment Method based on Endpoint Modeling (LIME). Expected Increase in Number of Extinct Species (EINES), which was calculated by summing the increments in extinction risks of each threatened vascular plant species due to land transformation, was used as an indicator of damage to biodiversity. EINES per land use category was calculated using data from the “Threatened Wildlife of Japan, Red Data Book 2nd ed. Volume 8, Vascular Plants” (hereinafter referred to as “RDB”). The EINES of wetlands and grassland was relatively high. The number of species that were assumed to exist in forestland was large; however, the EINES of forestland was relatively low. It was considered to be influenced by the huge area of forestland in Japan. EINES of other land was also relatively high, and it was considered to be the reflection of the existence of species whose habitat is peculiar, such as limestone areas or high mountains. Damage factors developed for Japan in this study have broad potential application, as they have more general land use categories than those in LIME 1 and 2; however, it will be necessary to develop damage factors in other countries, taking into account threatened species categories and regional differences in the importance of various land use categories. It is also necessary to accumulate detailed data on threatened species across the planet to develop worldwide damage factors.
