Short summary
A comparative life cycle assessment of pork with different feed scenarios substituting soybean products has been performed. Alternative scenarios used legumes, a protein crop mix, and amino acids. Results expressed per kilogram of feed depended greatly on the method used and the impact category considered. The inclusion of land use change increased global warming potential by up to 43 %. Results per kilogram of pork showed the amino acid scenario to have the least overall environmental impacts.
