Make the app as lightweight as possible. Remove images, animations and leave only the bare necessities. This saves data transfer and storage - which in turn saves energy.

Incentivize sustainable behavior, e.g. a small reward for bringing your own coffee cup. This can also be sold by SAS in the Eurobonus store or in flight.

Implement biodegradable plastics for in-flight service items and packaging to reduce waste and promote sustainable air travel practices.

You could offer cheaper tickets during these hours, encouraging passengers to choose more eco-friendly flights based on fuel efficient routes, altitude and time slots.
