We continuously push the boundaries of what is technically possible at sea and are actively engaged in the development of next generation environmental technology to achieve  net zero emissions for our marine operations by 2050.
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 ambition of 50% reduction in greenhouse gases by 2050.
Our efforts to reduce our emissions intensity though the introduction of increasing more efficient ships and operational improvement measures on existing fleet has resulted in a 28% efficiency improvement by 2019 compared to 2008.

Improving Quality of Ships Emissions

Today, 13 of 19 MSC Cruises ships are equipped with Exhaust Gas Cleaning Systems (EGCS) to reduce sulphur from ship emissions by 97 per cent, representing 74% of our total berths.

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.

Exploring New Technologies and Solutions

The adoption of LNG as fuel on up to nine of our future ships will allow a reduction of carbon emissions by as much as 20% compared with same ship using conventional fossil fuels. Compared to using conventional fuel, LNG reduces SOx emissions by more than 99% and NOx emissions by up to 85%. It also essentially eliminates particulate matter in the exhaust. Our first LNG-powered ship, MSC World Europa, will enter service in 2022.

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.

Energy saving technology on board:

Water and Wastewater Management

Our ships are fitted with the latest freshwater production plants and 80% of all freshwater used onboard is self-produced. This means that we minimise taking this precious resource from destinations ashore where freshwater can be scarce.

Signage on the ships encourages our guests and crew to consume water responsibly, and we are now installing flow restricting aerators on all taps and showerheads. This will help reduce our use of tap water by up to two-thirds.

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.

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.


For us sustainability means protecting the environment, supporting the people who work with us and choose to travel with us, as well as the communities and places that we visit and do business with.
