In this study, we evaluate elementary flows from various of data sources against a defined set of criteria to determine clarity, consistency, and interoperability in usage and management. This is both a problem for human readability and use as well as a problem for machine management of these data in LCA software and databases, both of which are critical to LCA data interoperability. Various conventions exist for naming (nomenclature), categorizing, using, and storing elementary flows in LCA data, which causes inconsistencies in use and implementation of elementary flows when using LCI, and LCIA data from multiple sources. Life cycle impact assessment (LCIA) methods provide impact characterization factors for elementary flows to enable impact estimation. They are used in life cycle inventory (LCI) models to represent use of raw resources in a process and emissions of pollutants and other materials into the environment. Elementary flows are essential components of data used for life cycle assessment (LCA).
