Finnish Ferry Firm to Operate First Carbon-Neutral Shipping Route in the Baltic Sea

18th August 2025
Wasaline has signed a biogas contract, which enables the Finnish ferry company to use only biofuels in the future. The company operates the ropax Aurora Botnia between Finland and Sweden across the Kvarken, the narrowmost region of the Gulf of Bothnia, a northern extension of the Baltic Sea.

A Finnish ferry company will begin operating the first carbon-neutral shipping route in the Baltic Sea to achieve its goal set for 2030.

The company, Wasaline, based in Vaasa, has also signed a biogas supply contract with Gasum and a FuelEU Maritime pooling agreement with Swedish ferry giant Stena Line. These partnerships would allow its 24,300 gross ton ropax ferry Aurora Botnia (see Afloat's previous coverage) to operate between Vassa and Umeå, Sweden, on biofuel and battery power.

Wasaline’s managing director, Peter Ståhlberg, said that this collaboration with Stena Line and Gasum will give the single-ferry-operated company the ability to achieve its carbon neutrality now as a forerunner for the industry.

The development means that all cargo and passengers travelling with Wasaline across the 4-hour Gulf of Bothnia route are sustainable with no extra charges applied for being carbon neutral.

The company’s daily operations on the Vassa-Umeå route, known as the world’s most northerly ferry route served, will run on certified biogas.

Ferry & Car Ferry News The ferry industry on the Irish Sea, is just like any other sector of the shipping industry, in that it is made up of a myriad of ship operators, owners, managers, charterers all contributing to providing a network of routes carried out by a variety of ships designed for different albeit similar purposes.

All this ferry activity involves conventional ferry tonnage, 'ro-pax', where the vessel's primary design is to carry more freight capacity rather than passengers. This is in some cases though, is in complete variance to the fast ferry craft where they carry many more passengers and charging a premium.

In reporting the ferry scene, we examine the constantly changing trends of this sector, as rival ferry operators are competing in an intensive environment, battling out for market share following the fallout of the economic crisis. All this has consequences some immediately felt, while at times, the effects can be drawn out over time, leading to the expense of others, through reduced competition or takeover or even face complete removal from the marketplace, as witnessed in recent years.

Arising from these challenging times, there are of course winners and losers, as exemplified in the trend to run high-speed ferry craft only during the peak-season summer months and on shorter distance routes. In addition, where fastcraft had once dominated the ferry scene, during the heady days from the mid-90's onwards, they have been replaced by recent newcomers in the form of the 'fast ferry' and with increased levels of luxury, yet seeming to form as a cost-effective alternative.

Irish Sea Ferry Routes

Irrespective of the type of vessel deployed on Irish Sea routes (between 2-9 hours), it is the ferry companies that keep the wheels of industry moving as freight vehicles literally (roll-on and roll-off) ships coupled with motoring tourists and the humble 'foot' passenger transported 363 days a year.

As such the exclusive freight-only operators provide important trading routes between Ireland and the UK, where the freight haulage customer is 'king' to generating year-round revenue to the ferry operator. However, custom built tonnage entering service in recent years has exceeded the level of capacity of the Irish Sea in certain quarters of the freight market.

A prime example of the necessity for trade in which we consumers often expect daily, though arguably question how it reached our shores, is the delivery of just in time perishable products to fill our supermarket shelves.

A visual manifestation of this is the arrival every morning and evening into our main ports, where a combination of ferries, ro-pax vessels and fast-craft all descend at the same time. In essence this a marine version to our road-based rush hour traffic going in and out along the commuter belts.

Across the Celtic Sea, the ferry scene coverage is also about those overnight direct ferry routes from Ireland connecting the north-western French ports in Brittany and Normandy.

Due to the seasonality of these routes to Europe, the ferry scene may be in the majority running between February to November, however by no means does this lessen operator competition.

Noting there have been plans over the years to run a direct Irish –Iberian ferry service, which would open up existing and develop new freight markets. Should a direct service open, it would bring new opportunities also for holidaymakers, where Spain is the most visited country in the EU visited by Irish holidaymakers ... heading for the sun!
