Technical Abstract: Beef producers in the U.S. have long been guided by efforts to increase productivity, decrease costs, and minimize environmental impacts, all of which directly support sustainable production systems. There is increasing public awareness and concern regarding environmental effects of agriculture in general and beef production specifically. There is a gap between our understanding of these impacts and our ability to make informed decisions to guide changes in breeding, feeding, manure management and other production practices to improve environmental sustainabily. Our objective was to evaluate a series of beneficial management practices (BMPs) for a cradle-to-gate sustainability assessment of U.S. beef production systems by linking the Integrated Farm System Model (IFSM) with a life cycle assessment software platform to provide full system evaluation of multiple environmental impact categories. Archetypical production systems across the US were constructed using IFSM simulations to supply lifecycle inventory flows for lifecycle impact assessment. The methodology is available for repeating this assessment in the future enabling evaluation of progress over the intervening time. Thus, longitudinal comparisons documenting continual improvement through time are supported by this framework. The impact assessment framework does not include an accounting for potential beneficial effects to ecosystem services associated with cattle ranching. This study characterizes the sustainability characteristics of US beef production and can serve as indicators for potential reductions in impacts driven by adoption of BMPs. It also provides basis for communication with consumers, including the food service and retail sectors regarding pathways to more sustainable production.
