Estimation of Co Emission
2

After RPK values are estimated based on three scenarios, fuel consumption
was estimated using Equation (1). The FD value used in Equation (1) was
estimated based on values given for the period till 2030. Detailed information
on these estimations are given in Kaymak (2019). As seen in Figure 2, it is
estimated that FD will decrease by 1,5% by 2030. Yearly fuel consumption was
calculated using Equation (1)

Figure 2: the estimated values of fuel density till the year 2030 (ton/million RPK)

As part of the study, 3,153 ton CO /ton fuel value was used as the EF of the
2
jet oil used by all the airlines in Türkiye (IPCC, 2006). Using Equation (2), yearly
CO2 emissions were calculated.
