Sustainable travel with Viking Line

The sea is our lifeblood. It is as important as it is necessary to work for climate-smart travel with the welfare of the Baltic Sea in mind. And we are proud to lead the way when it comes to new solutions to reduce our environmental impact. Are you curious about how we work with sustainability? Take a look.

New technology is the (sea)way forward

Call us technical geeks if you will, but our environmental journey begins with our technological innovations.

we are now building one of the world’s most climate-smart vessels. But as early as 2013, we took a giant step with Viking Grace, switching to liquefied natural gas (LNG), with the result being large emissions reductions. In 2018, Viking Grace was also the first vessel to use Climeon’s Ocean Marine energy recovery system, which enables heat from the engines to be converted into electricity. The next time you turn on the light in your cabin on Viking Grace, it is probably using waste heat that has been converted into electricity.

But our technological advances do not stop here. With the help of our brand-new Azipod propellers, optimized hull, recycled cooling, the potential to convert waste heat into electricity and dynamic ventilation and lighting, you can look forward to a greener and more beautiful experience when Viking Glory takes to the Baltic Sea in 2021. Its tank will naturally be filled with LNG.

Sustainability in measures both large and small

What are we doing at Viking Line to reduce our environmental impact? Actually, a great deal – and every effort counts.

  • We do not discharge any wastewater into the sea.
  • All waste generated on board our vessels is transported ashore for recycling or for some other form of treatment.
  • Instead of using environmentally hazardous paint on the bottoms of our vessels, we use divers to brush the vessel bottoms.
  • Food waste in the restaurants on Mariella has been reduced 40%, thanks largely to our more efficient food preparation processes in the kitchen. In four months, that is equivalent to 70,000 portions!
  • Great focus on fuel optimization. Six of Viking Line’s vessels use low-sulphur fuel with a maximum of 0.1 per cent sulphur by weight. The seventh, Viking Grace, uses sulphur-free liquefied natural gas (LNG). Viking Glory, which will be launched in 2021, will also run on LNG.
  • A number of measures to reduce nitrogen oxide emissions have been carried out. Catalytic converters are used on Cinderella, and humid air motor (HAM) technology is used on Mariella.
  • Three vessels that are moored in port for an extended period are connected to the land-based power supply in order to reduce emissions.
  • Using a unique vacuum process, heat is converted into electricity on Viking Grace.
  • Since 2018, the Company’s buses run on Neste MY Renewable Diesel™, a 100% renewable fuel.
  • The carrier bags you get in the tax- and duty-free shop are biodegradable and made from recycled plastic.
  • The herring in our buffets is MSC-certified.
  • All coffee served on board is organic.
    In general, only multiple-use containers made of porcelain, glass or melamine are used for serving.
  • Single-use bowls are made of either maize (corn) or cellulose.
  • In 2018–19, among the measures taken, we replaced plastic straws on board (1.5 million a year!) with straws made from biodegradable material.
  • Take-away cups in the cafés either have the Nordic Swan ecolabel or are PEFC-certified hot beverage cups.
  • Volume products such as cream, butter, yoghurt, fermented milk and eggs that are served on board the vessels are produced solely in Finland. Milk and potatoes are produced in either Finland or Sweden.
  • To fight food waste, portion-size servings are offered in the buffets.
  • In the cafés, sandwiches are made on the spot to meet the demand.
  • From April 1, 2020, all boiled eggs on board will come from free-range chickens. That's one-third of the egg products served! But we aim higher. From 2024, we will only use eggs from free-range chickens on our vessels.

10 tips for a climate-smart trip

Follow us on our journey towards a greener future and sustainable travel. Here are a few concrete tips for what you can do to help out.

  1. It is better to make an extra trip to the buffet table instead of filling your plate right away. Perhaps it is the first time you are trying a new dish. Serve yourself a sample portion to start with.
  2. Switch your car for a bike. You can certainly take your bike on board. Moreover, all of our destinations are bike-friendly.
  3. Bring your own water bottle and fill it with tap water on board.
  1. Fill the beds in your cabin with travel friends.
  2. Buy organic in the duty- and tax-free shop. There is an enormous range of items available – you can even buy clothes from the Viking Line Collection that are made 100% of recycled textiles.
  3. Carry your purchases home in our biodegradable carrier bags.
  4. Try our tasty vegetarian and vegan dishes in the buffet.
  5. Leave your car at home and take the bus to the vessel instead. In Sweden for example, we offer connecting buses that run on renewable diesel from 60 locations.
  6. Turn off the lights and TV when you leave your room.
  7. Download the Viking Line app so that you will not need to print your boarding confirmation.

We link Europe together

You might be thinking, wouldn’t it be better to leave the Baltic Sea alone? But you need to rethink that.

... and the majority of our vessels carry large cargo volumes of goods each day between Sweden, Finland and Estonia. A full 92% of Finland’s exports are transported by sea! The EU promotes a sustainable, environmentally-adapted future for maritime transport as part of the European transport infrastructure. And we want to be part of that and do our duty.

Green partnerships

At Viking Line, we have chosen to work in partnership with a number of environmental organizations for sustainable travel.

... our archipelagos and support scientific research on protecting the Baltic Sea’s unique maritime environment. In March 2019, we donated 50,000 euros to the Finnish environmental organization Keep the Archipelago Tidy Association and the University of Helsinki’s Tvärminne Zoological Station. Together we are stronger.

Håll Skärgården Ren rf

Håll Skärgården Ren rf (The Keep the Archipelago Tidy Association) is a national environmental organization in Finland for all boaters and people who travel in and around Finnish waterways. All operations are aimed at keeping the archipelago and the Finnish marine environment tidy. The association promotes and looks for solutions to make boating and other water activities as well as harbour operations more environmentally-friendly.

The Keep Sweden Tidy Foundation

We support Håll Sverige rent (The Keep Sweden Tidy Foundation) in the fight for a litter-free Sweden, both on land and at sea. The foundation works actively to reduce littering, promote recycling and increase environmental awareness among individuals and organizations.

Baltic Sea Action Group (BSAG)

BSAG is a not-for-profit association based in Finland that works to find solutions for re-establishing a good ecological balance in the Baltic Sea. This is to be achieved by providing scientific data to decision-makers and bringing together the appropriate stakeholders.

University of Helsinki (Baltic Sea research)

We work in partnership with Finland’s largest centre for Baltic Sea research – the Tvärminne Zoological Station, which is part of the University of Helsinki’s Faculty of Biological and Environmental Sciences. The zoological station is located at the entrance to the Gulf of Finland and is open year-round. Researchers from across the world come here to carry out top-quality biological research. The station was founded in 1902, so there is a lot of background information available to study long-term changes in the environment. The station is also located in a nature reserve that people can only visit for research and educational purposes.

Certifications and environmental awards

Naturally, we comply with the agreements and laws in effect concerning the environment and maritime transport. We happily do even more. And we have been richly rewarded for that.

... as well as the Group’s main office and subsidiary Viking Line Buss Ab are environmentally certified under the ISO 14001:2015 standard. Our organization and all our vessels are also certified in accordance with the International Safety Management (ISM) Code’s requirements for safe management and pollution prevention.

Our ambition to achieve sustainable travel has also resulted in a number of distinguished environmental awards over the years, something that we are especially proud of. That shows we are on the right path. Now we are aiming even higher!
