A commodity supply mix for more regionalized life cycle assessments

Life cycle assessment (LCA) is an approach used to calculate the potential environmental impacts of a product over the course of its life cycle. Supply chain information is essential for LCAs, but there are few detailed assessments of production and consumption practices for specific regions. This study introduces the commodity supply mix (CSM), which relies on mapping national or international supply chains, as a way to gain a deeper understanding of these issues.
