The more promising CO2 reduction potentials range from about 60-80%, but the mitigation benefit could well change significantly if LUC and ILUC scenarios relevant for an actual feedstock cultivation scheme are applied. Any climate mitigation benefit for a pathway may be fully offset, e.g. if land of high carbon stock is converted for feedstock cultivation (SWAFEA, 2011), as is for instance seen in the Partner 2010 study, where rapeseed oil HEFA has a 37% reduction without LUC effects, but a 12% increase for the considered LUC scenario. For other types of feedstock the LUC impacts can be even more pronounced, as demonstrated in the Partner 2010 study, where a considered scenario for palm oil (not listed in table) resulted in GHG emissions more than seven times higher than conventional jet fuel.
