We are fully committed to playing our part in addressing climate change and promoting ocean biodiversity. We are determined to accelerate our transition toward net zero emissions by 2050 from our marine operations. We work closely with leading technology companies, shipyards, and fuel providers to push the boundaries of what is possible. In 2022, we launched our first LNG powered ship – a significant milestone on this important journey.

Pathway to decarbonisation

We are on track to 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. In 2022 we already achieved 33.5% reduction. Since carbonizing marine operations is one of our main priorities our ambitious goal is to reach net zero greenhouse gas emissions for our fleet by 2050.

Improving operational efficiency
We are on track to achieve the International Maritime Organization’s 40% carbon intensity reduction for the maritime industry well ahead of the 2030 target
, in 2022 we already achieved 33.5% reduction. Many sustainability measures are, in fact, simply good business sense because they reduce costs in addition to our environmental footprint. Energy efficiency is an obvious example of that, with LED lighting and heat recovery systems having that dual impact. Anti-fouling paint reduces drag, and lower speeds and trim optimisation make the voyage more comfortable and reduce fuel consumption. We continue to advance the digitalisation of our energy efficiency programme.

In 2022, we completed the installation of Oceanly Performance on all ships in our fleet. This platform enables the continuous monitoring of thousands of raw data points on the position, speed, weather, engine load, flow meters, fuel consumption, torque meters, and all other on-board equipment which can be connected to a central data collector, allowing continuous analysis and onboard adjustments to maximise efficiency.

Improving Air Quality | MSC Cruises

Responsible waste management

Minimising local pollutants:
We are a guest in all the ports we visit and strive to minimise our impact on local communities and their environment, particularly in the area of air emissions.  

Reducing emissions to air:
Connecting to shore power enables us to turn off our ships’ engines and connect to the local electrical grid to run our onboard systems. With electricity travelling to the ship through a specially designed transformer at the dock, this process prevents emissions produced from our onboard diesel generators, improving local air quality as well as reducing noise and vibration levels – benefitting both the environment and the surrounding communities.


Treating our wastewater: Once we have used the freshwater, we ensure that it is treated before discharging it into the ocean. All vessels within our fleet have wastewater treatment systems, cleaning wastewater to ensure our full compliance with wastewater discharge rules in any part of the world’s oceans we operate in. Since 2017, all new MSC Cruises ships have been equipped with Advanced Wastewater Treatment Systems (AWTS). 


Treating ballast water: ballast water helps keeping the weight and centre of gravity balanced. By optimising the trim, we can have a significant impact on a vessel’s energy demand. We have adopted a strict treatment regime to remove any threat that bacteria, microbes, small invertebrates, larvae, and other microorganisms in the ballast water may have as they are transported from one location to another.
