This paper investigates the variability in global "well-to-refinery-entrance" carbon intensities of crude oil trade pathways. Using high-fidelity datasets, optimization algorithms, and bottom-up emission estimators, the study reveals significant variability (4.2–214.1 kg-CO₂-equivalent/barrel), highlighting the potential for CO₂-equivalent savings (1.5–6.1 Gigatons) by prioritizing low-carbon pathways. The research emphasizes the need for improved emissions reporting and supply chain traceability to inform effective decarbonization policies.
