Executive Summary
Table 1 provides results from this LCA the regional analyses with two comparative studies. The comparative LCA studies are from Putman et al. (2018), A Retrospective Assessment of US Pork Production: 1960 to 2015, and Blonk (2023), Sustainability performance of pork production. Comparisons of LCA studies should be considered for approximate benchmarking only. Underlying data sources, literature, methodologies, scenarios, and inputs including diet composition varied significantly across LCA studies and affected the LCA results (Attachment 5).
