Agenda Introduction Adding GIS data to inventory locations Implementation of regionalized LCIA methods Regionalized LCIA calculation Analysis of regionalized LCIA results Outlook Q&A

Regionalized LCIA is model sophistication Commonly, in Life Cycle Assessment (LCA), the impactassessment (LCIA) is performed ignoring any regionaldifferences. But, there are good reasons for considering a regional variationin the impact assessment, although this adds complexitysource: dennis140, aloe vera plantage, Fuerteventura (left); Gario, cows meadow, Texel ResultsOutlook

Regionalized LCIA is model sophistication More and more regionalized LCIA methods available, e.g.: ImpactWorld http://www.impactworldplus.org LC-Impacthttp://www.lc-impact.eu Ecological Scarcity y-method-2013 Enhanced EI99 odsCalculationResultsOutlook

Regionalized inventory datasets Differences in the inventory are considered as far aspossible (e.g., national databases, different processes forelectricity generation per country, ationsLCIAmethodsCalculationResultsOutlook

Combining regionalized inventory andLCIA methods Some databases include elementary flows specific fordifferent regions, to facilitate the regionalized LCIAcalculation, e.g.: LC-Inventories.ch Not considered a pragmatic approach for ResultsOutlook

Location editor in openLCA 1.5 KML data can be added to each location: Draw polygons, lines or points in the KML editor Multi-geometries of the same type are allowed Write the coordinates in the “Text editor” Import KML or EcoSpold2 files with geographic data, ww.census.gov/geo/maps-data/data/tiger-kml.html If no KML data is added, a point will be created with theaverage latitude/longitude when saving the nResultsOutlook

Parameterization of LCIA methods The attributes contained in a shape file can be used asparameters in the LCIA method. Shape file specifications: Coordinate reference system: WGS84, EPSG:4326. Only numerical attributes can be used as parameters inopenLCA. There must be a single layer in each file. Unique names for the attributes to be used as parameters. The features should not overlap (e.g. the same shape filecannot contain features for Europe and Germany). Shape files are stored in the database, and can be exportedas zolca or JSON ResultsOutlook

Parameterization of LCIA methods Different options for the content of the shape fileparameters:1. The parameter represents the impact factor of aspecific substance and impact nResultsOutlook

Use shape file parameters in the LCIA method The default value and uncertainty will be calculated dependingon the “External source (i.e. shape file)” selected The default value can be modified and will be used in: “Quick results” and “Analysis” calculations In “Regionalized LCIA” calculations, when a process has alocation without KML data or has no location Formula evaluation in the LCIA esultsOutlook

Calculation procedure for Regionalized LCIA The intersection between shape files features andprocess geometries is calculated by openLCA A weighted mean calculated for each regional parameter(p(F1)*L(F1) p(F2)*L(F2) ) (p(F1)*A(F1) p(F2)*A(F2) ) /AResultsOutlook
