From page 21...
... The model year within EDMS was set to 2011 to force a low sulfur content fuel for the GSE. This choice was made because using an earlier year with high sulfur content fuel would overstate the benefits of an alternative jet fuel, and an alternative jet fuel will not realistically be available in large quantities while the high sulfur content diesel fuel is in use; therefore, the reductions in SOx would be overstated.

... Of this portion, diesel GSE makes up 78%. Unlike the aircraft flight schedule, which provided actual flights and aircraft used, the GSE vehicle inventory was produced by an internal EDMS algorithm.

... The aircraft NOx emissions for ULSJ are reduced by the change in fuel burn 0.5%, while the NOx emissions for 100% SPK would be reduced by 2.1% and the 50-50 blend would be reduced by 1.3%. This result is likely conservative since preliminary studies show that NOx is reduced with SPK fuels.

... With Jet A, the largest contribution to PM2.5 is due to sulfates. With each of the alternative fuels considered, the ultralow sulfur content of the fuels makes the sulfate contribution negligible.
