Biojet fuel can also be used to count towards the biofuel mandates in the EU under the RED and in the US as part of the RFS2, in which case accounting rules would apply to the fuel supplier. However biojet fuel use towards these mandates has been very limited, as they have so far been fulfilled primarily in the road transport sector, so the systems are relatively untested in relation to biojet fuel. In the EU, the Netherlands is the only country to have actively implemented the provision for biojet fuel to count towards the RED target in their national legislation. Nevertheless lessons can be learned from the key characteristics of the accounting methods required for road transport biofuels under these three legislative drivers.
