Reducing air pollution 

We have installed hybrid Exhaust Gas Cleaning Systems (EGCS) on 15 of our cruise ships which reduce SOx emissions by 98%, and Selective Catalytic Reduction Systems on 3 ships, which reduces NOx by up to 90%.

Underwater radiated noise

Our latest low-noise propellers and innovative hull designs reduce impacts on marine life and enhance Guest and Crew comfort. 
 
Water is precious
Over 80% is of our freshwater is produced on board. Aeration faucets cut consumption by up to 2/3 and advance wastewater treatment systems purify all water consumed.

Waste management
We keep waste to a minimum and separate paper, aluminum, glass, plastic and other recyclables for delivery to specialist port recycling facilities 

New fuel types
In 2022, we have launched MSC World Europa, our first LNG-powered ship. LNG largely eliminates sulphur oxides (SOx) emissions and particulate matter in the exhaust, reduces nitrogen oxides (NOx) emissions by up to 85%, and CO2 by up to 25%.  

Maximising Energy efficiency
LED lighting and smart heating, ventilation and cooling systems have contributed to achieving a fleet-wide 35% efficiency improvement since 2008. 

Shore power capability
11 of our ships are now able to connect to shore power, potentially enabling the onboard engines to be switched off whilst in berth 

Advanced analytics
Digitalisation is allowing us to anticipate and address inefficiencies in systems and equipment, and provide the crew with specific guidance for performance improvements. 

Heat recovery
Heat recovery systems allow the intelligent redistribution of heat and cold where needed throughout the ship. 

Trim stabiliser
A software application monitors the ship’s stability to support the deck officers in optimising the vessel’s trim – and therefore reducing fuel consumption. 

Reducing drag
Our ship hulls are coated with hi-tech paints that slow the growth of marine organisms, thereby reducing drag and improving energy efficiency. 

Ballast water treatment system
All ballast water is filtered and UV treated before being discharged at sea to ensure that it does not contain harmful aquatic organisms and pathogens.

In addition, MSC World Europa is equipped with a technology called “fuel cell", which enables significant greenhouse gas emissions reductions. Fuel cells create energy through an electrochemical reaction that is much more efficient than traditional internal combustion engines
 
We are also collaborating with technology and energy providers to support and test other knew solutions and new lower or zero emissions fuels.

Our hybrid EGCS can operate in an open or closed loop, allowing wash water to be collected in holding tanks to avoid direct discharge into ports or other sensitive areas.

5 of our ships are fitted with a selective catalytic reduction (SCR) system, which significantly reduces nitrogen oxides (NOx) from the ship exhaust and transforms it into harmless nitrogen and water, through advanced active emissions control technology. SCR systems will be on fitted on all future ships. 
 
11 of our ships, including all our new ships, are been fitted with shore power capability. This enables onboard engines to be switched off, cutting emissions. We are committed to using these systems whenever shore power is available.

We keep the ocean as it should be: clean. All the water used on board our ships is treated and cleaned to excellent international standards before it goes back in the sea.  All our ships are equipped with wastewater treatment systems designed and maintained to the highest standards – even higher than many on-shore facilities.
 
Although regulations generally allow untreated sewage (blackwater) to be discharged once a ship is travelling more than 12 nautical miles from land, we do not allow this under normal operation in any circumstances and require that the ship requests permission from the Company, when a rare and exceptional discharge is necessary.
 
Regulations also permit the disposal of bilge and oily water at sea if it has been treated through an approved oily water separator. However, we follow a strict policy not to do this and instead discharge ashore all bilge and oily water, where it can be properly treated at approved port reception facilities.

Less ‘drag’ means smoother movement through the water and less noise. Insulation of potentially noisy equipment such as engines and generators on board the ship will also have a positive impact on reducing under water noise.
 
We are also reducing noise thanks to our propeller which is equipped with an air lubrication system that balances the pressure around the propeller. As the ship moves through the water, the propeller blades create low pressure and the bubble system is able to equalize this therefore reducing the noise.

Heat recovery systems allow the intelligent redistribution of heat and cold where needed throughout the ship. In particular we ensure the waste heat from the engines does not go to waste but is used to heat water for the laundry and to generate freshwater from seawater through evaporation.
 
In addition, our ships gather and continuously transmit thousands of different data sets to our expert teams on shore. We use this data to better understand how we operate, and to improve efficiency across all areas of our operations.

Scientific studies over the years have revealed that this practice has allowed bacteria, microbes, small invertebrates, larvae and other microorganisms to be transported from one location to another around the world, potentially threatening local ecosystems.
 

To prevent this, and to comply with strict international regulations, all our ships are fitted with a ballast water treatment system that complies with the standards set by the UN international governing body, the International Maritime Organization (IMO). This system protects against the involuntary introduction of invasive marine species. In 2022, 100% of ballast water was filtered and UV treated before being discharged at sea.

Training our crew, not only to handle waste, but to understand the importance of waste management, is central to what we do. Our crew members receive ongoing training to ensure they remain abreast of the highest standards and can inform our guests about the need to separate and recycle.

The Environmental Compliance Officer on every ship is responsible for ensuring waste management protocols are followed.
