Soybean is a major vegetable protein crop often considered to be sustainable alternative animal products. Assessments of soybean sustainability resort Life Cycle (LCAs), which are difficult compare due methodological inconsistencies. This study carried out an innovative method for harmonized comparisons production between farms assessed in different studies. Rather than collecting LCA results, we collected Inventories (LCIs) and then calculated the global warming potential (GWP) land use impacts each farm. For this, systematic review following PRISMA methodology collect LCI data from 19 studies representing 126 six countries. A comparable analysis showed higher variability GWP (0.27–1.53 kg CO2e/kg soybean) previous reviews, but within range similar results original As same were used all cases, this can explained by differences systems locations, with minimum contribution variability. Farms Iran United States exhibited highest emissions, primarily driven synthetic fertilizer use, irrigation, energy use. Using studies, substantially lower GWP. Brazil non-biogenic greenhouse gas emissions soil biotic capacity loss occupation, while Italian demonstrated minimal impacts. These findings underscore need region-specific mitigation strategies, despite being limited gaps on residue management, representativity sample farms, lack detail irrigation data. There pressing more complete reporting results.
