Harmonizing soil carbon simulation models, emission factors and direct measurements used in LCA of agricultural systems

Key Points

• Emission factors varied significantly across different simulation models, indicating substantial discrepancies in projections.
• The analysis utilized life cycle assessment methods to evaluate the impact of soil carbon on agricultural sustainability.
• Cross-comparison of soil carbon simulation models highlighted the need for standardization in agricultural lifecycle assessments.
• Improving model harmonization could enhance accuracy in estimating carbon emissions from agricultural practices.
