The list

Analyzing the Fuel Management System data of Stena Flavia on the Nynäshamn to Ventspils route led to several energy saving changes lowering the fuel consumption and emissions. One of them: a slight tilt of the propeller. Sometimes the smallest things really can make a big difference.

Following the successful pilot test on Stena Vision in 2012, close to our entire fleet has been equipped with the energy saving FMS upgrade. Late 2017, Stena Scotia sailing from The Netherlands to UK was our 28th vessel to be crossed off the list.

Following the preceding success of URD, five more vessels were modified with new bulbous bows in the years to come, including Stena Scandinavica and Germanica on our Gothenburg to Kiel route, as well as Stena Vision and Spirit frequenting the waters between Gdynia and Karlskrona. In 2016, Stena Danica on the Gothenburg to Frederikshavn route became the last vessel so far to get this fuel-saving modification.

On September 23 of 2016 a modified Stena Germanica carried out her maiden voyage on only methanol, putting a new ferry fuel on the map.

The cooling system on board Stena Danica on the Gothenburg to Frederikshavn route has been equipped with an engine that runs only when cooling water is needed, thus minimizing electricity consumption and effect on the environment.

Holyhead Port in Wales is Stena Line’s biggest port with more than 2,900 ships passing every year. In 2016 we installed 768 solar panels on the terminal, garage and shop buildings, providing the port with 164,000 kWh of green energy yearly.

We’re training our colleagues to be to recognise and assist customers with hidden disabilities.

Our Extra Loyalty club members benefit can now gain additional points when purchasing Better Choice products onboard.

The climate impact of each dish is presented in our menus allowing our customers to make an informed decision.

By cooking food fresh to order in our casual dining restaurants we significantly reduce the volume of food waste and improve the quality of our food at the same time.

We’ve replaced the vast majority of paper based promotional materials with digital screens onboard and in our ports.

We’re aiming to have 15% of our shop assortment classed as ‘Better Choice ‘ with alternative benefits for the environment.

Fair to nature, fair to the producers. Since 2015, the million cups of coffee served on board every year are all certified by the Rainforest Alliance.

We clean the vast majority of onboard surfaces with a solution made from salt, water and electricity. In addition, over 60% of other detergents are classed with environmental labelling’s.

In 2023 we launched a training that is mandatory for everyone at Stena Line, explaining the fundamentals of Sustainability.

Stena Line is using artificial intelligence in a pilot project to find out how we can support our captains and officers to save fuel and reduce carbon emissions. Read more here.

In 2015 we launched the first version of SAVE, our very own online employee-training program for minimizing energy consumption on board and ashore. Since then more than 3,000 employees have taken the course every year saving several-fold on kilowatt hours and waste.

By installing water purification filters and introducing tetra pack still water we’ve reduce the need for single use plastic bottles. We’ve also replaced all other plastic bottles with canned beverages.

Electric-powered trucks now have priority access onto our freight vessels at the port of Gothenburg. That’s just one of the big little things we have done for a more sustainable future. 

All our fish and seafood come from sustainable sources and are all MSC or ASC certified.

All our single use coffee cups, lids, salad containers are now 100% plant based.

It is not only at sea we work with electrification. We recently added yet another electric car to our land fleet at the port of Masthugget in Gothenburg, 1 of 4 ports where we use electric vehicles. Electric cars are also used in Hoek van Holland/Europoort, Halmstad and Nynäshamn.

Our ports have really increased material recycling. Last year 33% of waste plastic, metal, paper and glass was material recycled, while an additional 44% was used for energy recycling. This is an all-time high!

During 2018 we connected our 14th vessel to green shore-side electricity. By having 14 “connected ships” we reduce CO2 emissions with close to 14,000 tons/year. This is equivalent to the annual emissions of 7,500 passenger cars.

Speedpilot is an advanced cruise control system that optimizes a ship’s engine effect during a trip, making sure it arrives on time on as little fuel as possible. In 2015 Stena Mersey on the Belfast to Liverpool route was our 14th vessel to be equipped with Speedpilot.

We have developed an artificial intelligence-model that suggest the most fuel-efficient way to perform each sailing. The model will help our captains and officers to sail smarter and reduce fuel consumption

Early 2018 we passed certification for ISO 14001:2015, an international standard for environmental management systems and a tool for the company to improve in the sustainability field.

Early 2018 we equipped our first vessel, Stena Hollandica on the Hoek van Holland to Harwich, with ultrasonic transducers on the hull to minimize fouling.

Oil from our kitchens on board is recycled and used for a variety of purposes. In the UK it’s turned into biofuel, while the Scandinavian oil is turned into new raw material for the chemical industry such as soap and plastic.

Early 2018 we kicked off a new battery-power project by installing batteries to Stena Jutlandica on the Gothenburg to Frederikshavn route. Initially the batteries will power the ship’s thrusters, used to maneuver the vessel in to port. The next step is to run our main engines on battery power on short, inshore distances in close proximity to cities. And then who knows? In a not-too-distant future, hopefully this is how our ferries are run altogether.

Stena Line’s Energy Saving Program (ESP) was launched in 2006 in line with our goal to reduce fuel consumption. Eleven years later, as the main-engine regulators of Stena Scotia were replaced, project number 300 was completed.

In 2017 we connected all light port vehicles digitally to be able to follow, analyze and plan their loading in a more efficient and energy saving way.

In 2017, Port of Trelleborg in southern Sweden was added to our list of onshore-power sharing ports. This allowed another two of our vessels to turn off their engines in favor of green electricity while in port, making a total of 13 Stena ships now connected to onshore power. It also helped us treduce carbon dioxide emissions by more than 12,300 tonnes in 2017.

We always aim to use greener and better ingredients in our restaurants and cafés. For example, 100 % of all milk served on board has been organic since 2016.

Finding the right balance between draught at the bow and the stern will affect the total draught hindering the vessel. By loading Stena Scandinavica to make its bow deeper than the stern, we manage to save up to 7 % fuel on the Gothenburg to Kiel route.

As a step on the road to fairer food on board, we took the decision to put all of our eggs in the free-range basket.
