Key priorities

We at Tallink Silja operate on amazing, yet vulnerable Baltic Sea area. We want to take good care of our operational environment and encourage our clients and partners to do so as well. Environmental responsibility is our common project. In addition to versatile actions towards protecting the environment, we target our social responsibility actions especially to children. Similar to protecting the environment, it demands responsible actions and sense of community from all of us to support the children in their early steps in life.


Tallink Group's Sustainability cornerstones, focus areas and certifications.

Responsible and certified operations

Responsible and certified operations

We are committed to obeying all international and local laws, regulations and other applicable legal requirements and rules. Our fleet operates in accordance with the MARPOL-AFS agreement, which sets the cornerstone of maritime law towards protecting the environment and preventing pollution by ships.

All Tallink Group vessels are awarded with the ISO 14001 environmental certificate. This is the most widely recognised international environmental certificate model, which helps companies to improve their level of environmental protection and demonstrate their commitment to responsibility. Furthermore, our actions are audited on a regular basis.

Sustainable Travel Finland label

Sustainable Travel Finland label

Tallink Silja is awarded with the Sustainable Travel Finland label as the first shipping company in the Baltic Sea. The Sustainable Travel Finland program, run by Visit Finland, is an environmental program designed for Finnish tourism companies and destinations to develop more sustainable practices. The label is only granted to those companies and attractions within the travel industry that operate in a manner that is ecologically, socially, culturally and economically sustainable. The label ownership is audited every two years and criteria and targets are monitored carefully. Tallink Silja has renewed the STF label again and it is valid until August 2026.

  • Environment - Emissions and carbon footprint

    Emissions and Carbon footprint

    The principles of environmental protection are important part of our company strategy. The protection of environment is noticed in all actions from developing the functions to utilizing the most advanced technologies.

    Fuel and engines →

    The fuel consumption and amount of emissions are affected by many factors like passenger numbers, cargo amounts in tons, actual distance from port to port and weather conditions.

    We have been able to decrease the emissions by using low sulfur fuel, navigating economically and using catalyzers and modern engines. The waste heat from the engines is saved and reused on board for example to general heating.
    Real time fuel monitoring system on Bridge →

    Bridges on vessels have fuel monitoring system that helps optimizing the operation of ship and lower the consumption of fuel, energy and emissions. Control of fuel consumption allows eliminating fuel theft in a fleet and thereby helps to reduce total fuel expenses and fleet costs. Ships operating on same routes are compared with each other in fuel consumption. Information is also shared within ships for better optimizing in certain weather and wind conditions on specific spots on route.

    Our company is pioneer on using ship simulators on trainings. The officers are training regularly for unexpecting situations in ship simulators. Additionally, we run annual joined trainings together with maritime rescue authorities, police forces, fire department, harbor and Traficom.
    Slower travel speed →

    With slower travel speed we can use lower power output on engines, and this way reduce emissions. It is common that ships depart little bit early from ports – of course not until all passengers are onboard. On Helsinki-Stockholm route we also operate with special winter timetables when travel time is longer. Winter timetable is valid from beginning of September until end of May.
    Exhaust gas →

    In order to reduce the exhaust gas on ships staying on ports longer than 2 hours, since 2010 the power production during harbor time is maintained with fuel that has less than 0.5% sulfur. From 2015 all our ships changed to fuel that has 0,1 % sulfur.
    Shore power →

    Using shore power has huge impact on climate emissions, but it also benefits the residents near harbors as it causes less noise. When arriving to the port, the onboard diesel generators will be switched off and the vessel is connected to the shore power supply network. The ships’ energy load is then transferred to the port’s onshore power supply seamlessly, without interfering with any of the services provided onboard. By shutting down the assisting engines that produce electricity in harbor, we reduce the climate emissions 60-80%. It is profitable to use shore power on ships that stay in harbor more than 2 hours.

    The usage of shore power is planned together with harbors in Helsinki, Tallinn and Stockholm. Stockholm Värtan was the first harbor that started using shore power for Silja Serenade and Silja Symphony, operating on Helsinki-Stockholm route, on summer 2019. Tallinn harbor followed during year 2020 to offer shore power for Europa and Baltic Queen. In 2022 also both LNG powered Shuttle ferries Megastar and MyStar (delivery on Q2/2022) will plug into the local grid for quiet and emission-free overnight layovers in the Port of Tallinn.

    In Helsinki Olympia terminal the shore power was ready in 2020 and will be deployed during summer 2021. West harbor will also have its own shore power during summer 2021.
    Read more about shore power
    Nontoxic paints and divers as hull cleaners →

    The hulls of the group’s vessels are regularly cleaned by divers who, when conducting this process, do not use chemicals that are harmful to the environment. The hulls of Silja Serenade, Silja Symphony, Baltic Princess and Galaxy are brushed and cleaned approximately 4 times during summer months, depending on the weather even more often.

    When the underwater hulls are clean the fuel consumption is 2-4 times less than on same route without cleaning. Equally the exhaust gases get smaller.
    CO2 emission comparison figures →

    Maritime transportation is an environmentally friendly way of traveling, when we calculate the emissions based on the actual and certified information..

    It is not simple to compare environmental emissions within different ways of transportation. When comparing the emission figures the ways of calculation must be noticed. Especially on shipping transportation it is good to notice that ships are carrying major part of foreign trade transport in Finland and maritime shipping is the most environmentally friendly way of transport when transporting big amounts of goods. Overnight maritime transportation also covers the emissions from the accommodation.

    Comparing the emission figures with other ways of transportation, the carbon footprint should be calculated with using mass method where allocation has been made on base of weight.

    Examples of CO2 emissions per passenger (year 2018):
    • Helsinki-Stockholm 20-24 kg/passenger (Helsinki-Stockholm flight according to ICAO emission calculator 41-64 kg/passenger, according to Finnair calculator 52-88kg/passenger depending on the aircraft type).
    • Helsinki-Tallinn (LNG powered vessel) 7,8 kg/passenger (Helsinki-Tallinn flight according to Finnair emission calculator 23,47 kg/passenger)
    According to our calculations the LNG powered vessel, like Megastar, results 30 % less CO2 emissions than vessel operating on same route by using low sulfur fuel.
    General CO2 cuts, objectives and measuring in seafaring →

    International Maritime Organizations IMO has made decisions on cutting the CO2 emissions in March 2018. The decision was to reduce carbon intensity of international shipping (to reduce CO2 emissions per transport work), as an average across international shipping, by at least 40% by 2030, pursuing efforts towards 70% by 2050, compared to 2008.

    IMO also decided to cut annual greenhouse gas emissions from international shipping by at least half by 2050, compared with their level in 2008, and work towards phasing out GHG emissions from shipping entirely as soon as possible in this century. These restrictions apply to the whole seafaring, not only new vessels.

    The CO2 emission levels are measured and followed by ship-specific accuracy and results are reported to EU Commission. The EUR MRV (Monitoring, Reporting, Verifying) regulation requires ships to monitor and report their CO2 emissions, fuel consumption, transport work and average energy efficiency.

    Basically different shipping company’s collect data from fuel consumption of each ship that is later audited and verified by independent 3rd party verifier. Other transportation fields do not have similar kind of global, actual usage-based data collection system.

    The EU MRV (Monitoring, Reporting, Verification) Regulation system:

  • Environment - Waste recycling

    Waste recycling

    Metal, plastic, glass, cardboard, organic and special waste are recycled appropriately onboard. Handling and amounts of waste are audited regularly by international MARPOL regulations (Marine Pollution).

    Mixed waste is always transported to incineration plant where the waste is turned into among other things heating energy.

    Plastic usage →

    On Tallink Silja vessels we are giving up of all excessive plastic. On shops we only offer paper or reusable shopping bags and using of plastic straws has been reduced radically and replaced with biodegradable ones.

    In restaurants and cafeterias single use dishware are used as little as possible and unnecessary plastic usage has been minimized. Single use dishes and plastic Club One cards are abandoned in stages. We also cooperate with our suppliers to reduce the plastic packaging.
    Black and Grey waters →

    The accumulating black (toilet waste) and grey (sewer and washing waste) water are pumped directly to city’s draining network during harbor visits. From drains the waste waters flows forward to the wastewater treatment plants. Waste waters are never pumped into sea – we have absolutely zero tolerance on letting any waste waters into our precious Baltic Sea.
    Organic waste in the future →

    Organic waste is accumulated, depending on passenger numbers, for example on Silja Serenade on Helsinki-Stockholm route 8000-14 000 kg in a month.

    Our goal for the future is to be able to further process organic waste into fuel. On ships we are also investigating if organic waste could be used for composting. We are working closely together with professionals on different fields.
    Further processing of waste oil →

    The waste oil from our ships are transferred to further processing and cleaning on shore. This way it could be reused for example on power plants.

    Lately we have been happy to try out machine for further processing and cleaning of waste oil on Silja Symphony on Helsinki-Stockholm route. With this method the waste oil can be reused onboard even more effectively.
    Detergent, lighting, lamps and printing

    We are constantly using environmentally friendly detergents and applicators which help us to act more responsible towards environment. The laundry is done on shore by company who is using only detergents without phosphates.

    Tallink group has been following the development of lighting and lamp technology for a long time. Light bulbs have been changed to energy efficient light bulbs and - fluorescent lighting tubes. In the future the trend will be towards Led-technology.

    The company staff has reduced printing radically both on land operation and on board.
  • Environment - Tallink Siljas Environmental partners

    Tallink Silja's environmental partners

    Tallink Silja is cooperating with several partners to do good together for the environment and community.

    Sustainable Travel Finland →

    One of the most significant partners is Visit Finland. Their relatively new environmental programme Sustainable Travel Finland is designed for Finnish tourism companies and destinations to develop more sustainable practices. Tallink Silja was awarded with the Sustainable Travel Finland label as the first shipping company in the Baltic Sea. The label ownership is audited every two years and criteria and targets monitored carefully. Tallink Silja has renewed the STF label for 2021-2023 in September 2021.
    John Nurminen foundation →

    Tallink Silja signed a new cooperation agreement with the John Nurminen Foundation in Finland for 2023 with the aim of raising vital funds for the protection of the Baltic Sea. Tallink Silja and John Nurminen Foundation have cooperated on Baltic Sea protection projects also in previous years, but not on this scale. In addition to raising funds for the protection of the Baltic Sea environment, the cooperation will also see the organizations working together on awareness raising, highlighting key concerns and ways in which everyone can get involved in its protection.

    As part of the cooperation, Tallink Silja will make a donation to John Nurminen Foundation from every Tallink Silja Line branded water bottle sold on board the company’s vessels during 2023.
    ”Bottled water is the number one sales article on board our vessels although reusable water bottles and simply drinking tap water on board are increasingly popular too. We hope that by the end of the year we will have been able to support the vital activities of John Nurminen Foundation with approximately 20 000 euros through this year’s campaign and our customers and staff will know much more about how they can help protect our Baltic Sea and the environment in general,” Piret Mürk-Dubout, Management Board Member of Tallink Grupp, added.

    "We act on a daily basis to reduce eutrophication of the Baltic Sea and to preserve the diversity of marine nature. At the John Nurminen Foundation, we are grateful to Tallink Grupp for their support, which we will use to improve the well-being of our beloved Baltic Sea, to fight against the loss of biodiversity and to strengthen the awareness about the Baltic Sea and its heritage. “ Erkki Salo, Fundraising Manager at John Nurminen Foundation said.
    Climate partners →

    Climate partners is cooperation network of City of Helsinki and business sector that aim to reduce the climate emissions, strengthen the competition of companies and finding new business possibilities.

    Tallink Silja's commitments:
    • Tallink Silja's objective is to reduce fuel consumption on Helsinki-Stockholm route 0.5. % in a year, based on the consumption of main engines tons/nautical mile (ton/nm) and current summer-winter timetables and normal ice conditions during winter months.
    • Tallink Silja is committed to decrease the paper waste of its head quarter 5 % in a year, based on 230 employers at the office.
    • The environmental awareness of staff both on land operations and on ships is developed with internal communication.
    Baltic Sea Action Group (BSAG) →

    Baltic Sea Action Group BSAG is 2008 established, independent, non-profit foundation that actions are based on cooperation between various operators.

    Our staff has been trained to be part of WWF volunteer oil prevention team as part of Baltic Sea Action Groups commitments. Tallink Silja has also been involved on BSAGs project to reduce the nutrient releases by shipping operations.
    Co-operaton with The Finnish Environment Institute for the Baltic Sea →

    Tallink Silja is working closely together with The Finnish Environment Institute to help monitor the state of the Baltic Sea. In practice this means that sensors and pumps are installed to the bottom of Silja Serenade to collect the water for further analyses. Silja Serenade’s engine room has small laboratory that analyses the water samples and sends real time information to the scientist in The Finnish Environment Institute. The water samples collected on Silja Serenade monitors especially the temperature of the surface water, level of saltiness and concentration of weed in the water.
  • Responsible food and supply chain

    Responsible food and supply chain

    We offer responsibly produced culinary experiences to our customers. The food on our vessels is always made of quality materials that we purchace from local suppliers whenever possible. The certification of responsible seafood is part of our work on sustainable development.


    All our 11 passenger ships have been awarded MSC certificate, the most reliable environmental certificate for sustainable and trackable fishing.

    MSC certificate for fish and seafood continues our work towards sustainable development. By seeing the blue MSC labels in ships restaurants, customers can be sure that the labelled products are from sustainable fisheries that catch fish in ways that ensure the long-term health of a stock or species and the wellbeing of the ocean.
    Local food →

    Food is big part of successful cruise experience. Our goal is to supply the fresh, high class materials from local suppliers whenever possible. Due to high customer numbers this is not always possible. For example, the Baltic herring on all our vessels is produced by local fisherman Vento Aalto from Pyhämaa, Uusikaupunki in Finland.  
    Vegetarian and vegan food →

    Tallink Silja is developing the vegetarian and vegan food selection on ships together with clients and for example with social media influencers. Our aim is to meet the needs of vegetarians and vegans even better.  
    Reporting the origin of meat →

    The materials and products to ships restaurants are bought from local suppliers whenever possible. Meat products are supplied from different countries, but we aim to use Nordic meat when the availability is guaranteed. The menus onboard changes with every season and we do our best to choose the materials produced on neighbouring countries (Finland, Sweden, Estonia).

    Our suppliers are reliable and approved by authorities and to whom quality we can trust. The availability of the products is also a big factor on our decision making. In all our actions we aim to be as responsible as possible.  
    Egg commitment →

    On Tallink Silja vessels over 1,5 million eggs are consumed every year only on Buffer breakfasts. Tallink Group is gradually changing towards using only eggs coming from open air chicken coops by 2025. This is one part of our goals on using more responsibly produced materials.  
    Food waste →

    We have been cooperating with WWF to reduce the food waste. WWF organized workshops for the crew where the overall environmental impacts of food were discussed, and actions on how to reduce the food waste in kitchen were considered. We inform our also passengers about food waste and how they can impact on the subject both as a consumer and as restaurant client.

    WWF Youth organization has produced variety of materials to our ships that helps us to get the attention of our passengers. In addition, we share information about environmental impacts of food to our loyal customers and other passengers.  
    Tap water →

    Our suppliers are reliable and approved by authorities and to whom quality we can trust. The availability of the products is also a big factor on our decision making. In all our actions we aim to be as responsible as possible.

    Drinking water on board is in separate water tanks and the quality is under strict monitoring of authorities. It is totally safe and environmentally friendly to fill your own water bottle instead of buying yet another plastic bottle of water.  
  • Safety

    The safety culture on ships has been developing in a long process of time. Safety-thinking is based on right organization on board, high technical level, strong processes, high professional abilities and continuous training of the staff.

    Monitoring of the maritime safety→

    Finnish authorities are supervising vessels that operate under Finnish flag. In Tallink Group these vessels are Silja Serenade on Helsinki-Stockholm route and Baltic Princess on Turku-Stockholm route. The authorities of all destination countries Tallink Group is operating work closely together.

    Safety regulations are controlled both internationally and locally. The border guard oversees maritime rescues and acts on preventing the environmental damages on the sea. Additionally, border guard is multidisciplinary maritime law enforcement authority.

    Finnish Transport and Communications Agency Traficom is auditing licences and registers of maritime safety. Internationally maritime safety is controlled by International Maritime Organization (IMO) that is operating under UN. In our operations we follow, among others, the instructions of the International Safety Management (ISM) and International Ship Port Facility Security (ISPS).
    The safety trainings→

    Safety trainings are operated on our ships weekly. Our staff is practising for example to put out the fire, evacuation of the ship, first aid skills, operating in the dark and using of different safety equipment’s.

    Our company is pioneer on utilizing the ship simulators in training. The sea officers practise regularly for unexpected situations in ship simulator. Additionally, we run annual joined trainings together with maritime rescue authorities, police forces, fire department, harbor authorities and Traficom.

    Sometimes also the 4 legged officers are training on our vessels. Read more about how the Police and Drug dogs took over Silja Serenade to train their professionalism in sniffing.

    SecurePax project (1.1.2019-31.12.2023) is undertaking where digital safety services and solutions are piloted for the first time in maritime passenger terminals. The objective of the project is to ensure the sustainable and effective sea traffic in the long run. The partners of the project are Tallink Silja and Viking Line. The project gets funding from EU’s flagship programme Connecting Europe Facility (CEF).

    Ensuring the safety of passenger transportation is especially challenging in core harbours of Turku and Stockholm. The ships operating between these two harbours has such shorts visits in port, only 1 hour, that the embarkation and disembarkation of foot passengers and loading and unloading of vehicles must be done without any delays to keep the vessels in their tight schedules. This limits greatly the possibilities of checking the passengers, vehicles and luggage.

    SecurePax project aims to find solutions for this challenge. The best solutions and pilot technologies will be carried out in the new joint passenger terminal in Turku harbour when the project is finalized. The successful results will also be shared to other maritime operators in Europe. Tallink Silja passenger terminals in Turku and Stockholm harbours will execute several new untraditional digital safety and ICT solutions.

    The most important goals in the project for Tallink Silja:
    • Checking the identity of passengers in the passenger terminals and information exchange between authorities. This is done by mapping and testing the suitable technical solutions for registering the passenger information digitally.
    • Investigate possibilities of preventing the unwanted passengers embarking the vessels together with authorities. For this the handling and practical reading of international vessels and port operations safety system (ISPS-code) will be clarified.
    • Take into use solutions that detect passengers and dangerous objects in vehicles, luggage or with passengers. For this the available technics are investigated, suitable solutions are tired out and technical adequacy and obeying of the rules are being evaluated.

  • Social responsibility

    We work persistently in cooperation with different partners to support children, families and communities for better life. With Kummit Ry we enable purchases of much needed medical devices and with Hope Ry we can support children in families with low income to have hobbies and spare time activities. Being the Official partner of Santa Claus, we share good will, joy and hope for the children around the world. More locally, we want to be part on creating sporty lifestyle and encourage children to move.
