title: Original Supporting Information to "Learning Curves in Prospective Life Cycle Assessment"

description: This folder contains all the supporting information to "Learning Curves in Prospective Life Cycle Assessment" in its original state at the time of publication in Environmental Science & Technology. For any updates or corrections to this original data, consult the respective folder.The supporting information is further organized into folders. The main folder contains <b>Supporting Information.pdf:</b><b> </b>This is a copy of Supporting Information which is also available at the journal. It is included here for completeness.The folder <b>Figures</b> contains:21 .PDF files for figures in the main text and Supporting Information.pdf36 .JPG/.PNG files for figures in the main text and Supporting Information.pdf1 .xlsx file for the underlying data of Figure S4.15 .txt files with the codes required to recreate the Sankey Diagrams with SankeyMATIC.The folder <b>Step 4 - LCI model</b> contains:<b>Foreground.xlsx:</b> spreadsheet file with the life cycle inventory of the foreground system which can readily be imported in Brightway2.The folder <b>Step 5 - Supply chain contribution analyses</b> contains:<b>ReCiPe 2016 E - midpoint-to-endpoint.xlsx:</b> spreadsheet file with the results for the midpoint-to-endpoint contribution analyses using the Egalitarian versions of ReCiPe 2016<b>ReCiPe 2016 H - midpoint-to-endpoint.xlsx: </b>spreadsheet file with the results for the midpoint-to-endpoint contribution analyses using the Hierarchist versions of ReCiPe 2016<b>ReCiPe 2016 I - midpoint-to-endpoint.xlsx:</b> spreadsheet file with the results for the midpoint-to-endpoint contribution analyses using the Individualist versions of ReCiPe 2016<b>jupyter_notebook.ipynb:</b> Jupyter notebook file for reproducing the contribution analysis<b>jupyter_notebook.html:</b>.HTML version of the Jupyter notebook file.
