Short summary
Operational strategies such as eco-efficient flight routing have potential to reduce aviation’s climate effect. A collaborative workflow integrating weather forecast, climate response modelling, flight planning, air traffic control, and climate assessment was developed and tested in D-KULT. Innovative developments demonstrate substantial progress on how to identify alternative trajectories, highlighting remaining challenges with uncertainties in weather forecast and non-CO2 climate effects.
