Travel light = bring less than 8 kg. If you do so, you should be rewarded with points. If not, SAS will use the extra money you have to pay for sustainability investments.

Travelers register final destination, SAS sends taxi sharing offers via SAS transfer = lower taxi costs and individual receipts for passengers.

Eco-friendly air travel with quieter flights and reduced carbon emissions

Create an ability to share a seat in your car with other passengers on the flight. It's better than everyone riding their car.

Motivate and educate travelers and employees more on how to travel more environmental friendly, and illustrate the benefits of choosing the path towards sustainability.

Present sustainability data for the flight in the infotainment system, with for instance bio-fuel stats, # meals pre-selected and how much carbon emissions was saved.
