Sustainability in the Swine Industry: Understanding the Life Cycle Assessment of the Pork Supply Chai

Publish Date: April 1, 2022

The overarching goal of the swine industry is to provide high-quality protein to feed the world’s growing population. Improvements in production efficiency are continually being made to create a better and more sustainable product. Sustainability in the swine industry can be calculated using a Life Cycle Assessment (LCA). An LCA is a holistic approach to analyze the cumulative environmental impacts of the different phases of swine production. Swine production LCAs can inform producers and consumers how certain production practices impact the environment. The methodology of an LCA can be divided into four sections: goal and scope definition, inventory analysis, impact assessment, and interpretation.
