Supplementary calculations for the comparative life cycle assessment of electricity technologies in Greece

This workbook contains the transparent input values, harmonization choices, validation checks, and worked calculations that support the figures and tables of the associated article. It compares a reference small modular reactor configuration with solar PV, wind, combined cycle gas, and lithium ion storage across life cycle greenhouse gas emissions, operational water use, land use, waste, and critical materials. All values derive from publicly available, cited sources. No new primary data were generated.
