Environmental impact assessment for beef cow-calf systems with grazing was conducted using the procedure of LCA. The environmental impacts of the system with grazing on abandoned cultivated lands were evaluated to be smaller than those of the housing system. If all beef cows under the housing system in the Chugoku region are changed to be managed with the yearlong grazing system (grazing on abandoned cultivated lands in spring to autumn, and on semi-natural grasslands in winter), 12,355 (t CO_2 eq) of greenhouse gas emission, 210 (t SO_2 eq) of acidification potential, 26.7 (t PO_4 eq) of eutrophication potential and 93.1 (TJ) of energy consumption will be reduced in an year.
