Remove the disposable earphones in SAS Go. Offer them on request. Install Bluetooth audio so that pax can connect their own wireless headphones to the IFE system.

Offer a ”Sustainable Comfort Kit” with eco-friendly amenities like reusable water bottles, organic snacks and bamboo sleep accessories

Use real cutlery as disposable cutlery is not sustainable, not even wood.

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.

Giving an incentive and getting more passengers to travel light should reduce aircraft loading and fuel consumption. Alternatively allow more cargo.

When the crew collects trash before landing, why not make separate rounds for collecting, cans, plastic cups, paper, etc instead of collecting all trash in the same bin.
