Figure 2. Contributions of the different ingredients and life cycle stages to the land use impact categories:
a) BDP, Biodiversity Damage Potential; b) CRP, Climate Regulation Potential; c) WPP-MF, Water Purification
Potential through Mechanical Filtration; d) WPP-PCF, Water Purification Potential through Physico-
Chemical Filtration; e) BPP, Biotic Production Potential. All impacts expressed per functional unit (f.u.):
500g tub of margarine to be used as spread (Milà i Canals et al., 2012).
In conclusion, the type of oil, not only the total fat content, determines the overall impact and this is
mainly due to the differing yields of the various oil crops and hence the land occupation level. In addition,
the production system of the various oil crops (annual vs. permanent crops) and the sourcing region (biome)
have a significant effect on the contributions to the impact categories, as explained below.
