At MSC Cruises we believe cruising can be more sustainable. From introducing cleaner fuels across our fleet to producing freshwater on board, we are pushing the boundaries of what is possible at sea. Our growing fleet is a statement of our commitment to the future of this planet.

Decarbonising our marine operations is a core element of our sustainability strategy.

To demonstrate our commitment to this we have in place an ambitious goal of net zero emissions by 2050, which goes further than the current IMO (International Maritime Organizartion) ambition of 50% reduction in greenhouse gases by 2050.

Reducing Carbon Intensity

We currently estimate that we will meet the IMO (International Maritime Organization) intensity ambition of a 40% reduction by 2027 – three years earlier than the industry target date of 2030 set by the IMO and adopted as a goal by CLIA.

Since decarbonizing marine operations is one of our main priorities our ambitious goal is to reach zero emissions by 2050.

Energy Efficiency and Advanced Ship Design

For every new ship class that we develop, we completely revise the design to achieve optimal efficiency. We rethink the ship’s overall structure, deck space, weight distribution including the ship’s hull, rudder and bulbous bow to reach optimal hydrodynamics, aerodynamics and maximise energy and fuel efficiency.

Leading the energy transition

New technology and low carbon fuels are fundamental to our carbon reduction strategy. This is why in November 2022 we delivered  MSC World Europa , one of our latest ships and one of the most environmentally-advance ships at sea. MSC World Europa is powered by liquefied natural gas (LNG), reducing carbon dioxide by 25%, virtually eliminating Sulphur oxides and particulate matter, and reducing nitrogen oxides by up to 85%.

Improving Quality of Ships Emissions

Today, 15 of 21 MSC Cruises ships are equipped with Exhaust Gas Cleaning Systems (EGCS) to reduce sulphur from ship emissions by 98%.

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.

Water and Wastewater Management

Our ships are fitted with the latest freshwater production plants and 80% of all freshwater used onboard is produced from the sea using desalination technology. We even produce our own water to brew our own delicious beer!

This means that we minimise taking this precious resource from destinations ashore where freshwater can be scarce. On our newset ships we self-produce up to 3 millions liters each day, the equivalent of an Olympic swimming pool!

Reducing noise

Our ships are designed to reduce noise radiated under the water surface, thus minimising noise or vibration that might impact aquatic mammals. Noise reduction is achieved on various levels. A significant amount of effort goes into studying and perfecting the ship’s hull design, hydrodynamics and propulsion system.

Through extensive testing and simulations, MSC Cruises creates optimal hull design and bulbous bow to minimise resistance when moving through the water. 

Saving energy on board

Our ships’ lighting is provided by energy-efficient LED. The LED bulbs we use on our ships are up to 75% more efficient than traditional bulbs and last at least 7 times longer.

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.

Ballast Water Treatment

One of the challenges in operating a cruise ship is keeping the weight, centre of gravity, and stability requirements balanced and consistent throughout a voyage. To help us do this, there are tanks distributed in the lower part of a ship which can be filled with seawater to act as ballast.

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.

Cleaner water

Most of the water used on our ships is produced on board, with highly efficient systems producing clean freshwater from seawater. 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.

Solid Waste management

All our ships are equipped with comprehensive solid waste management and recycling facilities.

All organic waste, as well as recyclable disposable items including plastics, metals, paper and glass, are collected and separated by specially trained waste handling crew members. Waste is compacted, separated or incinerated, and residual waste is carefully delivered to dedicated port facilities.


Our sustainability programme is organized around four key pillars: Planet, People, Place and Procurement.
