Figure 8. Monte Carlo distributions of the total carbon footprint for (A) the Ausmelt case and (B) the double-flash case. Each software-database configuration was evaluated using 10,000 Monte Carlo iterations, with common random numbers applied to homologous contributions for paired route comparisons. Boxes represent the 25th-75th percentiles, central horizontal lines denote medians, whiskers extend to the most extreme values within 1.5 times the interquartile range, and colored points show a fixed random subset of 1,400 realizations for visual clarity. Red dashed segments denote the simulated means, with the corresponding mean values shown adjacent to each box. All boxplot statistics and reported uncertainty metrics are based on the complete 10,000 simulations. LCA: Life cycle assessment.
