The aim of this study is to assess the direct and indirect environmental impacts to be expected if the demand of biodiesel in
Spain increases to meet current European obligations. Two alternative pathways are compared under a consequential approach.
The first pathway is in fact the prevailing one and consists of
increasing the imports of soybean biodiesel from Argentina. The
second pathway consists of increasing the production of biodiesel
from UCO. To reinforce the results, emphasis is placed on the uncertainty assessment, as it may influence decision-making.
