Since Spring quarter 2020, the USLCI Database is now the first repo on the Federal LCA Commons (FLCAC) to be completely updated to the Federal Elementary Flow List (FEDEFL). The US EPA, the lead agency on the FEDEFL, worked with NREL to help map and convert the USLCI database to the FEDEFL. The EPA's Heavy Equipment Operation repo is also compatible with the FEDEFL (as originally compiled).
Per the emerging FLCAC standards & conventions, the FEDEFL will become a part of the core database structure across FLCAC repositories. The CORRIM Forestry & Forestry Products database is in the process of being converted to the FEDEFL and other repos will follow. The FEDEFL will provide greater standardization and interoperability for Federal LCA data and can also serve as a standard for elementary flows for a broader community.
Please note that there has also been a release of TRACI 2.1 LCIA Method repo on the FLCAC Collaboration Server that uses the FEDEFL nomenclature. This version of TRACI must be used in order to obtain results for life cycle impact assessment (LCIA) calculations on FLCAC data adapted to the FEDEFL (e.g., 2020 and later USLCI Database versions). A repo with ReCiPe 2016 Midpoint and Endpoint methods that are FEDEFL-compatible has also been published to the FLCAC.
