10 Top Eco-Friendly Cruise Ships

The cruise industry served 30 million people and contributed over $144 billion to the world economy in 2019. Today, it is on track to surpass these numbers. Cruising supports local economies and generates employment through tourism. However, it also leads to global warming.

Cruise Ships and other vessels are responsible for 3% of annual global greenhouse gas emissions. A report by the Pacific Standard revealed that an individual’s average carbon footprint triples when on a cruise. Hence, in terms of carbon emissions per person, cruising is worse than flying.

In a world where being sustainable has become the need of the hour, the cruise industry is undergoing transformation to become more environmentally friendly, though cases of greenwashing also abound.

However, as strict environmental regulations and environmental awareness among consumers are on the rise, many cruise lines strive to make the cruising experience more green and sustainable.

In an industry that is known for its carbon-spewing ships, excessive waste production, environmental violations and port over-tourism, practices like using paper straws and reusing linens onboard cruise ships are not enough.

The true change lies in achieving technology breakthroughs around using clean and alternative fuels and having a green port infrastructure. Not to forget, cruise ships should manage onboard waste in a responsible manner.

Some significant initiatives in this regard include the commitment of CLIA, Cruise Lines International Association, the biggest cruise industry trade association, to attain net-zero carbon emissions by 2050 and decrease carbon rates by 40% by 2030.

Per a CLIA report, over 15% of cruise ships making their debut in the next 5-10 years will have hydrogen fuel cells or electric batteries. Yet another important move will be zero-emissions docking, where ships switch off their engines and connect to the grid at port, reducing air pollution.

Now that we have discussed the impact of the cruise industry on the environment in brief and the need for sustainable cruising let’s look at the 10 top eco-friendly cruise ships.

1. MSC Euribia, MSC Cruises

This new energy-efficient cruise ship named after the ancient goddess Eurybia has to be the first on the eco-friendly cruise ship list. This ship’s construction began in 2021 during the pandemic and cost roughly €850m. The futuristic cruise vessel first set sail in June 2023, and her maiden voyage was unlike any other ship since she was powered by 400 tonnes of bio-liquified gas during the trip.

The ship has many measures in place to make it the most eco-friendly cruise ship. The 331 m Euribia has 4 dual-fuel engines that take LNG and marine gas oil. It also meets the IMO Tier III standards.

Like many other ships of the MSC Fleet, MSC Euribia is fuelled by LNG and cuts up to 20% of carbon emissions and 85% of the nitrogen oxide it produces.

The ship is energy efficient with smart cooling systems, LED lighting, ventilation and heating systems. It also uses oxide fuel cells to decrease emissions and renewable waste biofuels.

The ship has a wastewater treatment system that purifies saltwater and makes it drinkable. Its propellors generate less noise, and its hull is designed to lower drag and consume less fuel, lowering the ship’s environmental impact.

Per MSC Cruises, Euribia emits 19% less greenhouse gas per passenger per day than her sisterships running on traditional fuels. It also emits 44% less greenhouse gas daily than vessels constructed a decade ago.

2. Ambience, Ambassador Cruise Line

Second on our top eco-friendly cruise ships list is the majestic Ambience, a part of the Ambassador Cruise Line’s fleet. Ambience sailed for the first time in 2022. It employs several state-of-the-art eco-friendly technologies onboard, allowing it to sail to some of the world’s most pristine locations, like the Norwegian World Heritage Fjords.

The cruise line worked with a ship management company to upgrade this vessel in line with Environmental Social Governance to meet IMO’s highest emission standards in Tier 3.

Ambassador Cruise Line reported that from Ambience’s 1st voyage in April 2022, her emissions have decreased by 95% due to the use of systems that transform harmful gases into inert nitrogen and water vapour, thereby reducing nitrogen oxide emissions.

After the upgrades, she also saw a 7% reduction in fuel consumption, 80% less sulphur oxide emissions and a reduction in CO2 emissions of 5.358 tonnes annually.

In accordance with the Energy Efficiency Existing Ship Index regulations, the ship is equipped with a shaft power limitation, which restricts power by 25%. Hence, her speed of 18.5 knots is reduced to 16.25 knots.

It also has a sewage system and bio-digesters to convert food waste into heat and water, bottle washers, and a bottling plant.

3. Explora I, Explora Journeys

The luxury cruise ship Explora I of Explora Journeys is fueled by LNG and has shore-to-ship power capabilities. This vessel left on her 14-day maiden voyage, covering 7 destinations on 1st August 2023, from Copenhagen, Denmark.

According to the cruise line, the ship has provisions for battery storage, enabling future hybrid power generation. Due to the latest selective catalytic reduction technology, it reduces NOx emissions by 90%.
