Development of an emission inventory methodology for air traffic on the basis of a flight schedule scenario for a fast subsequent climate impact analysis

Abstract

This thesis presents an approach to assess and compare the climate impacts of different aircraft design and technology options. For this purpose, the metric condenses the timevarying CO2 and non-CO2 effects into a single meaningful quantity for an entire fleet of aircraft, considering the altitude-varying forcings by NOx emissions and by aviation induced cloudiness. Moreover, this metric has been enhanced by basing it onto a flight schedule by implementing a method of mapping and calculating the trajectory of any individual aircraft mission on a great circle path. Lastly, the climate impact of conventional Jet A-1 fuel, a drop-in fuel blend and a 100% Sustainable Aviation Fuel was analysed and assessed based on a simplified global flet composition and flight network structure.
