Fig. 3: CO2-eq emissions calculated using the GWP*100 method for an example fleet demonstrating the flow-based nature of the GWP*.

The inset figure shows the temporal emission profile; the main figure the CO2-eq response for each species (colours). For the comparison of fleets in this study (F-GWP*), the peak total value is used, in this example occurring in the year 2050. Note that the total value is dominated by the contrail impact and that different species have their peaks at later times. Therefore, the choice of which value to use is itself a trade-off between different emission species.
