Abstract | The way airlines plan flights is crucial, needing to consider route charges, fuel consumption, and expected delay on the route. However, their decisions also have important consequences for the climate, since choosing different routes can have very different impacts in terms of emissions of CO2 and other types of pollutants, such as NOx. Whilst, in general, low fuel consumption and low environmental impact go hand-in-hand, the different route charges set by the ECAC countries mean that cheaper routes have sometimes worse environmental impact. The Green-GEAR project is developing incentivisation frameworks to help re-align airlines’ decisions with low(er) environmental impacts. In this article, we present this issue in more detail, the methodology of the project, the modelling aspects, a stated preference survey, and the determination of climate hotspots. Further, we present the preliminary survey results obtained from test data from the consortium team, and a sample of climate hotspots. We use these test data to discuss the principles of the modelling of utility functions, and the integration of utilities and climate hotspots in a new route-charging scheme. |
