I am researching climate change mitigation strategies for aviation.
How can the aviation industry
reach net-zero emissions by 2050?

What is the climate impact
of contrails from aviation?
Modelling of contrail climate effects with the AviTeam and the CoCiP model (master’s thesis)
- Comparing contrails from domestic flights in Norway with all flights globally in 2019, contrail energy forcing per flight distance is -90%.
- Looking at the domestic flights in Norway in 2019, the Winter and Autumn months were responsible for 81% of the annual total contrail EF in Norway.
- Looking at the domestic flights in Norway in 2019, only 26% of the flight distance was travelled between the hours 18:00 and 06:00, but this time period accounted for 93% of the total contrail EF of the day.
- Looking at the domestic flights in Norway in 2019, it is found that 2% of the flights are responsible for 80% of the annual total contrail EF.
These large differences in contrail climate forcings are closely linked to the different amount of sunlight available at the time of flight, which depends on the seasons and the time of day. Thus, the results reveals the specific characteristics of contrails produced by domestic flights in Norway, and also underlines the necessity and value of geospatially and temporarily explicit emissions modelling tools such as the AviTeam for contrails climate impact modelling.
