Fig. 2: Comparison of the climate metric responses for full aviation emission scenarios.

Shown are the CO2-eq emissions calculated using each climate metric with a 100-year time horizon for the CORSIA (a) and FP2050 (b) scenarios. Each climate metric is represented by a different combination of colour, line style and marker for clarity. Also shown is the fuel use (red dashed line) and temperature (solid black line) response for each emission species calculated using AirClim for the CORSIA (c) and the FP2050 (d) scenarios. All values are calculated on a yearly basis—the markers for each species are differently spaced such that overlapping lines can more easily be identified.
