Data and code for a time-resolved and region-sensitive climate assessment of thirteen CO2 capture, utilization and recycling pathways for municipal waste incineration

Complete machine-readable data and calculation chain behind the manuscript "Time-resolved and region-sensitive climate assessment of thirteen CO2 capture, utilization and recycling pathways for municipal waste incineration". Thirteen carbon-management pathways for a modal Japanese municipal solid waste incinerator (300 t/d, 84,000 t/y) are harmonized onto one explicit fossil-carbon balance with cradle-to-grave-symmetric substitution credits, resolved across the ten Japanese electricity supply regions, extended with a CO2 impulse-response climate layer, and propagated through a shared-draw Monte Carlo analysis. The release contains 19 data files and the complete calculation chain: the 130 absolute pathway-region results and the 120 pairwise differences, the 50,000-row Monte Carlo master draw matrix and the draw-level outputs under both recycling boundary treatments, the 624 rank correlations, the Shapley decomposition audit over all eight background combinations, the 2050 regional evaluation, the hydrogen supply scenarios, and a unified calculation workbook that recomputes the governing equation with live Excel formulas as an independent implementation. A single entry point, run_all.py, regenerates every number, table and figure (Figures 2 to 6) from the fixed seed 20260702 and the input files shipped with the release. The reproduction was verified in a clean directory: 15 of 15 CSV files byte-identical and zero workbook cell or formula differences.
