Integrating 2G ethanol and residue valorization expands Brazil's sugarcane pathway to sustainable aviation fuel — Data and Code Package

Reproducible data and code package supporting the Nature Food submission by Zhaojie Chen (2026). Contains the calibrated techno-economic and consequential life-cycle assessment model for circular sugarcane biorefineries producing sugar, 1G/2G ethanol, and Sustainable Aviation Fuel (SAF) in Brazil. Includes the master data inventory, TEA/cLCA Python pipeline, Monte Carlo and Sobol' sensitivity samples, publication-quality figures, and primary source documents (ICAO CORSIA 7th edition, UNICA 2023/24, EPE, ICCT). All scripts are deterministic (fixed random seed) and reproduce every headline number in the manuscript. Subdirectories of the bundle (data, code, figures, sources) are provided as ZIP archives for reliable transfer; extract them after download to restore the directory structure described in README.md.
