Updating and Road-testing Life Cycle Inventory Data Review Criteria: Toward Global Consensus and Guidance On Data Quality Assessment.

Data quality of life cycle inventory background databases should be ensured in order to be useful for life cycle assessment (LCA) studies. However, databases do not always have procedures to evaluate the quality of the data sets in place. The Global Guidance Principles for LCA Databases of the United Nations Environment Programme (UNEP) in collaboration with the Society of Environmental Toxicology and Chemistry (SETAC) provide, among others, recommendations to enhance data quality through improved documentation and review.
