Figure 1

Average relative deviation (ARD) in relation to GHGE reduction (by steps of 10%) when minimizing total relative deviation (TRD) and applying constraints on nutritional adequacy, relative GHGE reductions, and additionally constraining the relative deviation (RD) of individual food items from observed food supply to a range between −75%/+100 and −75%/+200% (Model 3). GHGE, greenhouse gas emissions. The RD of the optimized solutions refers to the observed food supply during the school year 2015/2016.
