I am modelling the environmental impacts of aircraft transport services, which includes aircraft production. I am using Ecoinvent 3.8 apos_regionalized with methods in openLCA 1.11.0. From this, the process "aircraft production, passenger aircraft, long haul" |APOS, U, contains 8 different "kerosene" flow inputs, each from different regions (including RoW). I don't understand if all these need to be considered when modelling one item (one aircraft), or if I should consider only the RoW option for instance, as an average for the country that I am modelling (UK). Please, any suggestions?
Thank you in advance and have a good day,
