Reduced emissions in a jet fuel having aromatics content can be achieved by incorporating a quantity of an aromatic kerosene fuel blending component, preferably a bio-derived synthetic aromatic kerosene, comprising at least 90 wt.% of aromatics, less than 10 wt.% of indanes and tetralins and less than 1 wt.% of naphthalene into a jet fuel in a manner to meet the aromatic content specification forjet fuels. A jet fuel having aromatics content having reduced number-based nvPM emissions compared to equivalent total aromatics content petroleum-derived kerosene jet fuel is obtained.
