The goal of this study was to compare impacts of pork production and consumption in the US and EU. The impacts were calculated using life cycle assessment (LCA) methodology. The LCA provides quantitative, confirmable, and manageable models to evaluate production processes, analysis options for innovations, and improve understanding of complexity in agricultural production systems. Therefore, LCA can be an effective tool to identify and quantify differences in two systems. The environmental impact categories used in this study were: global warming potential (GWP), agricultural land occupation, fossil fuel depletion, and water consumption.
