This repository contains the scripts and own generated data developed for the article: Miranda Xicotencatl, B., Kleijn, R., van Nielen, S., Donati, F., Sprecher, B., & Tukker, A. (2023). Data implementation matters: Effect of software choice and LCI database evolution on a comparative LCA study of permanent magnets. Journal of Industrial Ecology, 27(5), 1252–1265. https://doi.org/10.1111/jiec.13410 The data folder contains the characterized results of three alternatives for the production of rare earth magnets (REMs), calculated with several versions of the ecoinvent database (v2.2 and cut-off v3.1 to v3.6), their life cycle inventories, the foreground data to reproduce their product system models and the data plotted in Figures 3, 4 and 5 of the related article. The file with the Data Underlying the Figures in the Main Article is: `dataPlottedInFig_3_4_and_5.xlsx`. The document BWimport in the repository guides the user through the interaction with the custom scripts necessary to reproduce the results of this research. It is available as a PDF and as an interactive Jupyter notebook (IPYNB). Please refer to the article and the first part of the supplementary information (SI1) for further details about the context and purpose of this repository.Note on foreground dataSprecher et al. (2014) made their foreground data partially available in a human-readable format under a CC BY-NC 4.0 license. The file `processDataCMLCA.xlsx` is based on their complete product system model and consists of an annotated human- and machine-readable version. This modified version also includes the allocation factors used by Sprecher et al. (2014) that were not reported in their original publication.Note on licensesThe data in the repository is based on the work by Sprecher et al.
