Scandinavian operator SAS is to scrap duty-free sales on board its aircraft in a bid to trim weight and save fuel.

The airline says the measure will be implemented in autumn, as part of its overall strategy to cut emissions by 25% by 2030 compared with the 2005 baseline. SAS says duty-free sales has been a “popular” service among those customers who have used it.

“But our passengers’ buying behaviour has changed and sustainability has become more important than ever before,” the carrier says.

“Withdrawing tax-free sales will reduce the overall weight of the aircraft, which in turn will reduce fuel consumption and emissions.”

SAS says it will instead introduce alternative solutions to provide “more modern” means for passengers to purchase goods during their trip.

“Every step on the way to sustainable travel is important,” says executive vice-president, commercial, Karl Sandlund. “Every initiative to reduce weight and thereby cut fuel consumption helps.”

SAS’s targets for 2030 also include 17% use of biofuel, the equivalent of its total domestic consumption.
