About ImpactWorld+toFEDEFLv1.0.7mapping.csv

This is a mapping file between ImpactWorld+ 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 ImpactWorld+ to FEDEFL flow mapping, exact flowable mappings were identified based on CAS number or substance name followed by manual identification of common flows. 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.
