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. 

Decarbonising our marine operations is a core element of our sustainability strategy. MSC Cruises is committed to achieving net zero greenhouse gas emissions by 2050.


Reducing Carbon Intensity

We believe that we will meet the IMO (International Maritime Organization) carbon intensity goal of a 40% reduction from 2008 levels well ahead of the 2030 milestone set by the IMO. 

Since decarbonizing marine operations is one of our main priorities our ambitious goal is to reach net zero greenhouse gas 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. In June 2023 we will deliver MSC Euribia, one of our latest ships and one of the most environmentally-advance ships at sea. MSC Euribia is powered by liquefied natural gas (LNG). LNG enables us to reduce CO2e emissions by up to 20% and virtually eliminate sulphur oxides and fine particulates, while reducing nitrogen oxides by up to 85%. Our next ships powered by LNG will be MSC MSC World America (2025).

Improving Quality of Ships Emissions

Today, 15 of 22 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.


Our ships are fitted with the latest freshwater production plants and 80% of all freshwater used onboard across our fleet is produced from the sea through desalination.

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.

Protecting wildlife

MSC Cruises is committed to supporting the health of our oceans. In 2022, following discussions with the International Fund for Animal Welfare (IFAW), Pelagos Cetacean Research Institute, OceanCare and WWF Greece, we agreed to re-route our ships on the west coast of Greece to reduce the risk of collision with endangered sperm whales in the Mediterranean. 

In addition, in 2023 we have partnered with marine conservation charity ORCA to deliver a comprehensive ship strike mitigation programme for the line’s deck officers to reduce the likelihood of collisions with whales, dolphins and porpoises in oceans around the world.

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.
