Supplementary materials of the PhD thesis "Evaluation du potentiel d'émissions négatives des technologies d'utilisation du CO2". Chapter 1: Life cycle assessment of bioenergy with carbon capture and storage system: Critical review of life cycle inventories Supplementary_Materials.xlsx Chapter 2: Life cycle assessment of carbon capture and utilisation as a negative emissions technology: recommendations and case study ESM1.xlsx: inventory data used to perform the LCA of the case study. ESM2.yml: conda environment to run the scripts and perform LCA with Brigthway v2. ESM3.ipynb: script to generate the Brightway2 database by importing the Excel® file and slightly modifying it. ESM4.ipynb: script to generate the data illustrated in Figure 12 ESM5.ipynb: script to generate the data illustrated in Figure 13 ESM6.docx: explanation of the CFF, chosen LCI results, the absolute LCA results and the full results of the contribution analysis. Chapter 3: Facilitating dynamic life cycle assessment for climate change mitigation SI_1.docx: presents the modified version of Temporalis and provides instructions on how to use the “environment.yml” and “Scripts_for_results_reproducibility.zip” documents to reproduce the results. environment.yml Scripts_for_results_reproducibility.zip Chapter 4: Is dynamic LCA necessary? evaluation with simplified temporal information Is_dynamic_lca_necessary.ipynb : script to be run in the same conda environment as the supplementary material of chapter 3.
