the more promising co reduction potentials range from about 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 eg if land of high carbon stock is converted for feedstock cultivation swafea as is for instance seen in the partner study where rapeseed oil hefa has a reduction without luc effects but a increase for the considered luc scenario for other types of feedstock the luc impacts can be even more pronounced as demonstrated in the partner 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
