    • Embodied material flow and GHG emission factors for U.S. imports derived from the GLORIA model: 2017-2022

    Metadata Updated: May 1, 2025

    The dataset provides a set of Import Emission Factors (IEF) for USEEIO models developed using the GLORIA v059a model. The dataset accompanies Addendum 2 "Import Greenhouse Gas Emission and Material Factors Derived from GLORIA" to EPA report "Estimating embodied environmental flows in international imports for the USEEIO Model" (https://cfpub.epa.gov/si/si_public_record_report.cfm?dirEntryId=362470).

    The import factors (IFs) are provided for 15 material categories and 18 GHG categories at the BEA summary and detail levels of sector resolution as reflected in file names. They represents an average for U.S imports that is derived as a weighted average of the import factors from all world regions/countries, weighted by quantity of imports. The sector codes for the import factor use the BEA 2017 NAICS based schema used in input-output tables which is the schema used by the associated USEEIO models. For example, US_summary_import_factors_gloria_2022_17sch.csv is a summary level IFs file. US_detail_import_factors_gloria_2022_17sch.csv is the detail level IEFs file. Concordance files are provided here that are used to map GLORIA commodities and countries to those used in USEEIO. The models are named according to an updated USEEIO naming scheme. See the supporting code on the USEEIO github site (link in references) for more details.

    This dataset is associated with the following publication: Ingwersen, W.W., J. Namovich, B. Young, and J. Vendries. Estimating embodied environmental flows in international imports for the USEEIO Model. U.S. Environmental Protection Agency, Washington, DC, USA, 2024.
