Planet

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.
 
DECARBONIZATION

Decarbonizing 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. We currently estimate that we can meet the IMO intensity ambition of 40% reduction by 2030 compared to 2008 by 2027, three years earlier than the industry target date set by the IMO and made mandatory for cruise lines by CLIA.
To support this goal we are committed to an annual efficiency improvement of 2-4% across our fleet though numerous energy efficiency measures for every single ship.

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

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.

MSC Virtuosa is our second ship, after MSC Grandiosa, to be 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.

To reduce emissions while in port, all MSC Cruises ships which have come into service since 2017 are fitted with shore-to-ship power so they can ‘plug in’ to the local power grid. A retrofitting program will ensure that any ship docking in a berth that offers shore-to-ship power will be capable of using it.

Our advanced technologies have allowed SOx and NOx emissions to be significantly reduced over time

Improving Quality of Ships Emissions

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.

We are also investing in a ground-breaking project that aims to integrate a Solid Oxide Fuel Cell (SOFC) technology demonstrator onboard MSC World Europa using LNG to produce electricity and useable heat. This process is around 25% more efficient than a medium speed internal combustion engine, thereby reducing the emissions by the equivalent amount.

At present, this technology has only been tested in a laboratory but if the onboard results match, or even exceed, our estimates then we plan to increase the scale of fuel cells to support energy needs of future ships.

In parallel, we are evaluating the use of batteries as a supporting energy solution, providing smart energy storage and a ready to use power reserve when required. The evaluation will incorporate full life cycle analysis to validate the large-scale use of batteries.

New technology and low carbon fuels are fundamental to our carbon reduction strategy

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.
All wastewater on board is discharged to sea according to stringent international, national, and local regulations in force.

Since 2007, we have equipped our new ships with Advanced Wastewater Treatment Systems (AWTS) that turn black and grey wastewater to near tap-water quality.

In addition, all our ships are able to discharge treated water at port where adequate port reception facilities connected to local wastewater treatment systems are available. This is notably the case in environmentally sensitive areas, such as the Baltic Sea.

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.

Our advanced wastewater treatment systems process wastewater to near tap water quality.

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.
To prevent this, and to comply with strict international regulations, 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.

We have adopted strict treatment regimes to remove threats of species transportation through ballast water

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.
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
