I am trying to find out what cost index was used in the calculation of aircraft fuel use in the Emissions Inventory Guidebook 2013 as the guidance document does not state it, any help would be greatly appreciated.

Hi hollyaed, cost index is not a parameter taken explicitly into account in the eurocontrol calculations so it was not used in the Guidebook. The cost index (CI) is the ratio of the time-related cost of an airplane operation and the cost of fuel. The eurocontrol data is based on actual fuel consumption for a selected number of flights combined with averaged statistics on aircraft operations. If the actual fuel consumption is based on some companies operating according to the CI principle, it is implicitly included but not taken into account as parameter determining the emissions. I hope this clarifies.
