| Outline of Final Research Achievements |
We performed LCA of beef production systems with year-around grazing, grass-fed (Yakumo Beef; Organic or Non-organic), grass hay-fed to compare their environmental impacts with the conventional system. The year-round grazing system led to a reduction in the environmental impacts per unit carcass weight of beef compared with the conventional system, with reductions in global warming potential (GWP), acidification potential (AP) and eutrophication potential (EP) of 8, 53, and 47 %, respectively, and in energy consumption of 36%. The Organic and Non-organic Yakumo Beef had much lower AP and EP, and energy consumption than the conventional system. The Organic system also had slightly lower GWP, but the Non-organic one had slightly higher GWP than the conventional system. The grass hay-fed system had lower AP and EP, and energy consumption than the conventional system, but had similar GWP with the conventional one.
