PARALLEL SESSION 3A: LAND USE CHANGE 8 th Int. Conference on LCA in the
Agri-Food Sector, 1-4 Oct 2012
lowest GHG emissions were obtained when substitution scenario “Imported Soybean meal” (ISM) is adopted
and the highest emissions when market price based allocation is applied. The implications of alternative
LUC scenarios were also evaluated, showing that the original land choice is a critical issue. It was not possible
to compare results from alternative cultivation systems (tillage and non-tillage) due to limitations of inventory
data. The results presented here suggest future work developing specific LC inventory and modeling
for tillage and no-tillage soybean plantation to allow a comparison between cultivation systems.
To assure the lowest LC GHG balance of soybean oil, severely degraded grassland should be preferably
used for soybean cultivation. The results demonstrate the importance of LUC on soybean oil GHG emissions;
however, large variations on the GHG balance were calculated between the various LUC scenarios.
