The Higg Product Tools use a variety of data sources. The main background data source is GaBi. Background datasets cover all relevant environmental flows, such as resource extractions, and emissions, as well as all material and energy inputs and products of an activity. Background datasets, for example, such as country-specific energy grid mix, are used to build models of each process. Using a single background database is important for consistency within the database. The Higg MSI 3.6 (2023) uses Sphera’s Life Cycle Assessment Datasets (fka GaBi) as its background database.
Primary data inputs come from manufacturers, databases, literature, and trade organizations. Data sources for each material or process are listed in the Higg MSI and PM under Meta Information when users click on a specific raw material or production process. Anyone may submit LCA data to the SAC to be reviewed and used to score materials in the Higg MSI through the MSI Contributor.
