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 (International Maritime Organizartion) ambition of 50% reduction in greenhouse gases by 2050.

Reducing Carbon Intensity

By the end of 2019, we had successfully lowered our carbon intensity by 28% compared to 2008. Whilst the pandemic has meant we have been unable to track accurately the carbon intensity improvements across our fleet, we currently estimate that we will meet the IMO 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.

Improving Quality of Ships Emissions

Our long-term goal is to achieve zero emissions across all operations, at sea and ashore. We aim to meet the industry target of 40% improvement in emissions intensity by 2030, compared to a 2008 baseline, as part of our journey towards achieving net carbon neutral operations by 2050.

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.  

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. 

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.

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.
