Towards
sustainable travel and cargo shipment
Environmental responsibility is part of our daily operations. We have worked consistently setting short-term goals to reach excellent long-term results.
Building sustainable and efficient transport
Finnlines plays a vital role in society by ensuring the continuity of freight and passenger transportation, maintaining essential maritime connections, and supporting national security of supply and international trade.
We at Finnlines aim to meet the international transport needs as efficiently and with the lowest environmental impact as possible. Substantial part of all the international freight transported over the Baltic Sea is carried by our vessels, which makes us an essential part of the logistics chains in the area.
Finnlines offers ferry crossings across the Baltic Sea with our ro-pax service that combines passenger and freight transport, which increase the utilisation rate onboard ships. Higher utilisation rates in routes and vessels guarantees the possibility to travel in an efficient way.
Shipping is a highly regulated industry via international, European, and national frameworks. In order to reach the environmental targets, new technologies must be developed and alternative fuels produced in the upcoming years. Finnlines supports the transition towards greener shipping and participates in developing low-emission maritime transportation.
Sustainability Review
2025
To advance these goals and report on our steps toward environmentally sustainable maritime transport, we published our first voluntary Sustainability Review on 13 March 2026.
New methanol-powered vessels ordered
Finnlines has ordered three new methanol-powered vessels, which are expected to enter the route between Helsinki and Travemünde in 2028–2029.
New and innovative Superstar-vessels
Environmental considerations were taken into account in the design of the new vessels, from the technical construction to the selection of individual suppliers. The ships use state-of-the-art technology such as an innovative air lubrication system and run on shore power in port.
Finnlines’ hybrid ro-ros
Each vessel provides a cargo capacity of 5,800 lane metres – equivalent to approximately 400 trailers – and is designed for the efficient handling of diverse cargo types, including oversized freight. The ships are equipped with advanced technologies which contribute to reduced emissions and support more sustainable sea transport services.
Two pathways to lower emissions: electricity and biofuels
Through our maritime transport services, we’re addressing the climate challenges that shape our future. Cutting emissions is essential not only for long-term business success, but for the well-being of our society and the planet. As the demand for low-carbon transport grows, we’re continuously developing our operations to deliver efficient and reliable solutions.
Green Lane – low-carbon sea transportation
Officially introduced in 2025, this low-emission transport service gives both freight customers and passengers a concrete way to reduce their carbon footprint and support the global green transition.
By using electric energy and certified biofuels, Green Lane can lower customer’s transport-related emissions – 100% with electric energy (TTW) and by up to 90% with biofuels (WTW).

Climate action
Finnlines supports the transition towards increasingly environmentally friendly shipping and contributes to the development of low emission maritime transport solutions.
Travel emissions
We want to improve the transparency and comparability of travel emissions. Since 2019, we have calculated passenger specific carbon dioxide emissions on our passenger routes.
Environmental sustainability
One of our key objectives is to reduce both total emissions and unit based emissions year by year. Our performance continues to improve through fleet renewal and route optimisation, benefiting both our customers and the environment.
Caring for the environment
In addition to air emissions, shipping has a range of other environmental impacts.
Recycling, reuse and the responsible use of resources are embedded in our daily operations. At the same time, we continuously work to reduce our environmental footprint and improve our environmental performance.
We monitor, measure and evaluate our progress regularly.
Our environmental management system complies with the ISO 14001:2015 standard and is audited annually by an independent external assessor.
