This is a mapping file between ReCiPe2016v1.1 flows and FEDEFL v1.0.7 flows. This mapping follows this flowmapping format at https://github.com/USEPA/Federal-LCA-Commons-Elementary-Flow-List/blob/v1.0.7/format%20specs/FlowMapping.md A flow mapping consists of matched flowables, contexts and units. Flowables are the names of the material or energy that come from or go to the biosphere (commonly referred to as substance). Context is a set of environmental media/compartments that describe the flow origin or destination (e.g., “air”). To create the ReCiPe2016 to FEDEFL flow mapping, exact flowable mappings were identified based on CAS number or substance name followed by manual identification of common flows. Duplicate names for substances exist in the original ReCiPe2016 source file which have different characterization factors and different CAS. In these cases, the entries with the currently recognized CAS are accepted and the other substances are ignored. Context mappings were manually created to enable impact assessment across most of the possible contexts available within FEDEFL. Mappings that occur in the primary contexts (e.g. air) are assigned to all possible sub-contexts which apply. The mapping are maintained in the FEDEFL GitHub Repository at https://github.com/USEPA/Federal-LCA-Commons-Elementary-Flow-List.
