Summary

This 2016 systems dynamics modelling study examined greenhouse gas mitigation potential across contrasting biodiesel feedstock systems—soybean in the Midwest and canola in the inland Pacific Northwest—accounting for agroecological variation and nitrogen use efficiency. Using Vensim® PLE software, the authors modelled interactions between cropping system, geographic zone, and nitrogen management to improve spatial resolution of life cycle emissions from expanding biofuel production. The findings suggest that GHG outcomes from biodiesel cropping systems vary substantially with location and nitrogen stewardship practices.

UK applicability

Findings are primarily relevant to North American biofuel policy and production geography. UK applicability is limited, though the modelling framework and emphasis on nitrogen efficiency and agroecological context may inform UK bioenergy crop assessment and carbon accounting for agricultural expansion.

Key measures

Life cycle greenhouse gas (GHG) emissions (likely in CO₂ equivalents); nitrogen use efficiency; agroecological zone classification; projected production area changes over time

Outcomes reported

The study used systems dynamics modelling to estimate life cycle greenhouse gas emissions and mitigation potential for canola and soybean biodiesel production across different agroecological zones and nitrogen use efficiency scenarios. The analysis examined how cropping system choice, geographic zone, and nitrogen management practices influence the net climate benefits of biodiesel feedstock production.
