Environmental performance of pig supply chains: Guidelines for assessment (Version 1)

Book excerpt: This is a living document produced by the Livestock Environmental and Assessment Performance (LEAP) Partnership. The document presents a methodology and provides guidance for the assessment of the environmental performance of pig supply chains. It provides users guidance on how to apply the life cycle assessment approach to pig supply chains. Demand for livestock products is projected to grow 1.3 percent per year until 2050, driven by global population growth and increasing wealth and urbanization. This projected growth places significant pressure on the livestock sector to perform in a more sustainable way. Currently, many different methods are used to assess the environmental impacts and performance of livestock products. This causes confusion and makes it difficult to compare results and set priorities for continuing improvement. The intention of this document is to provide an overview assessment of existing studies and associated methods that have used life cycle assessment for the evaluation of pig supply chains.
