Our new aircraft will make a difference to the planet. Over the next few years we will gradually be phasing in new aircraft, which will give us a fleet that comprises exclusively of modern, more fuel-efficient aircraft. Our new A320neo and A321neo LR (Long Range) aircraft from Airbus use 15-18 percent less fuel than the models they are replacing, and our new A350s from the same supplier use 30 percent less fuel than the A340s they are replacing. As a result, CO2 emissions will decrease correspondingly and other climate-impacting emissions will also be reduced. Another advantage of the new aircraft models is that they are also less noisy.

An aircraft has a long life, but our strategy is to upgrade engines, furnishings etc. on an ongoing basis over the life of the aircraft. By replacing the furnishings in existing aircraft, for example, we’ve reduced the weight of the aircraft by several hundred kilos. So, we’re improving the efficiency of our aircraft and, at the same time, we’re making our passengers’ onboard experience more comfortable and more enjoyable.

In addition, SAS and Airbus have partnered up in a joint research project around electric aircraft, which could revolutionise aircraft emissions through increased use of electrification in future generations of aircraft.

SAS has been supporting a number of electric aircraft development projects for some time now. Most of these concepts aim, initially, to develop aircraft with a range of one to two hours and a capacity of 15-20 passengers. The aim of the research project with Airbus is to work together to gain insights around the opportunities and challenges associated with the large-scale introduction of hybrid and electric aircraft in commercial traffic. This could revolutionise the development of more sustainable commercial flights.

The development involves more than just the aircraft themselves. Electric aircraft will require a brand new infrastructure, including, for example, new solutions for energy supply and charging at airports. In order to guarantee access to electricity from renewable sources, the aim is also to involve one or more energy companies in the partnership. By investing in new technology for the next generation of aircraft, we are helping to drive the development towards more sustainable travel, which will have far less impact on our climate than is the case today.

Biofuel has the same specifications as fossil fuel but emits around 80% less CO2 than conventional aviation fuel. It can be blended with fossil-based aviation fuel and is perfect for powering the jet engines that we currently use. As things stand, a maximum of 50 percent biofuel can be blended with fossil fuel, and currently we are nowhere near this limit.

The disadvantage of biofuel is that far too little biofuel is being produced and it is 3-4 times more expensive. That’s why SAS is involved in a number of collaborations to promote the large-scale, commercial production of biofuel in Scandinavia. For example, SAS has signed a letter of intent with Preem, who plans to build a facility which has the capacity to produce several hundred thousand cubic metres of biofuel a year. This would mean that we could potentially have deliveries of locally produced biofuel on a large scale from 2023.

Most of the biofuel we use today comes from waste from food production, for example recycled cooking oil, but in the near future we hope to be able to use fuel manufactured from residues from the forestry industry.

Carbon offsetting is just one of many environmental and sustainability initiatives within SAS, and comes into play after we’ve done everything we can to reduce our climate impact using current technology. SAS aims to reduce CO2 emissions by 25 percent by 2030 by using biofuel corresponding to the fuel consumption of all its domestic flights within Scandinavia.

We’ve been carbon offsetting all flights our employees’ trips with SAS for a long time now. Since April 2018 we’ve been including carbon offsetting as an integral part of the approximately 1.5 million youth tickets that we sell annually. At the start of 2019 we took the next step: to carbon offset all tickets booked using a EuroBonus number. With around 5.6 million members, EuroBonus is the most popular loyalty programme for travelers in Scandinavia. This means that we now carbon offset just over 40 percent of all the CO2 emissions that our planes emit.

Carbon offsetting is based on verified statistics, and the actual offsetting is done by Natural Capital Partners, a well-known organisation that specialises in working with companies to reduce and offset the emissions they generate in the best possible way.

One area where, since 2017, we’ve taken steps to increase our environmental sustainability is the cleaning of our aircraft. Keeping our aircraft shiny and clean isn’t just an aesthetic issue, it’s also a sustainability issue. A clean aircraft has less air resistance and therefore uses less fuel. One disadvantage of conventional aircraft washing is that it requires a large amount of water. It could take 13,000 litres of water to wash one A330. Clearly, this is not sustainable in the long term. That’s why we have started dry washing our aircraft. This involves applying a special cleaning material which we then wipe off using a special wet cloth. The material is 96 percent biodegradable and produces a surface that stays clean longer than with conventional washing methods.

Here at SAS, we are working on reducing weight in many different ways. We’re investing in a new fleet that uses modern materials that weigh less. The new Airbus 320neo, for example, uses lighter materials in the carpeting on the floor, and the fabric on the seats is also lighter. By redesigning the seat trays, we can also save valuable kilos on every aircraft. Another small detail that makes a big difference is changing the USB sockets. This isn’t something that our passengers will notice, but we’ll see a difference on every aircraft, and when you add it up across our fleet it will make a big difference in terms of kilos. We’re also replacing the carpeting and seat fabric in our existing aircraft. Overall, these initiatives will enable us to reduce the weight of our aircraft fleet by just over 2.5 tonnes.

There is also potential to save weight in the hold. SAS Cargo has started using containers that are 20 percent lighter than the ones that were used before. This alone will enable us to reduce our emissions of CO2 by more than 13,000 tonnes over a five-year period. As a passenger, you can also make a difference by not taking more baggage with you than you actually need.
