“We know that sulfur in the air is a problem for humans and for wildlife. A rough calculation by the International Council on Clean Transportation (a very reliable and unbiased source) found that a cruise emits at least twice as much carbon as a vacation on land. And the vacation on land is even considering flying to a destination, plus the emissions from staying in a hotel, while they didn’t include a flight to the port city in the cruise emissions. And cities design their ports (and pay) to include “outlets” for cruise ships.
Christmas: 10 Tips to Reduce Waste and Protect the Environment
According to U.S. news travel, Caribbean and Alaskan cruises remain the most expensive – with the average person needing to pay an average of $791 and $938 for a week-long cruise respectively for each region. Unsurprisingly, these remain some of the most popular cruise destinations besides Northern Europe and the Bahamas. If you want to read more about how the cruise industry really works, plus an overview of the tourism industry as a whole that will really make you think, Elizabeth Becker’s “Overbooked” is a classic on sustainable tourism. I originally published this article on sustainability in the cruise industry in October, 2020.
How are cruise lines reacting?
“For years the cruise industry has failed to make the changes and upgrades needed voluntarily despite a few bright spots, let alone comply with current rules. Many of the cruise company’s liners usually stop in the Russian city port of St Petersburg in the summer months, but are not willing to do so given the current circumstances. Icon was built to accommodate fuel cells, which produce electricity without combustion, to be used to power the lifts, but the batteries have not been installed due to a problem with suppliers.
Cleaning up cruise ships’ environmental wake
Cruise industry emissions fall under the jurisdiction of the International Maritime Organization (IMO) of the United Nations, which technically has the authority to force deep sustained emissions cuts across worldwide shipping. In practice, though, the IMO has historically been heavily influenced by those very interests, with many countries appointing industry representatives to their IMO delegations. Natural gas, also known as methane, is itself a powerful greenhouse gas. With a warming potential more than 80 times greater than CO2 over a 20-year timescale, the overall emissions picture of using LNG is likely worse for global climate change than if the cruise lines had stuck with petroleum. An analysis of ship schedules at Southampton found that between April 2022 and July 2023, there were about 300 days when at least one cruise ship was docked at the port, but the onshore power facility was only used 71 times over the same period. Our technology helps businesses to tackle their own carbon emissions without incurring a huge cost.
Cruise Ships and Plastic Pollution
“Scrubbers” are an expensive way of turning cruise ships’ air pollution into water pollution. Additionally, regulations and policies can be put in place to limit the environmental impacts of cruise ships. Cruise ship emissions can have a significant impact on air and water quality. Air pollution from ship engines can harm human health and contribute to climate change.
Your carbon footprint is high
A new TIME survey conducted by The Harris Poll backs up some of those points. To environmental campaigners, cruising stands out as perhaps the most polluting sort of vacation. But fully half of Americans surveyed consider taking a cruise to be “eco-friendly,” with only one in three regarding such vacations as being bad for the environment. It wasn’t long after that Skjeldam, officially appointed as CEO in October of that year, was on a Hurtigruten ship sailing past the Svalbard archipelago, home to the world’s northernmost inhabited town.

Studies have shown one cruise ship produces roughly the same amount of carbon emissions as 12,000 cars. Much of this rubbish is incinerated and disposed of at sea, putting countless sea creatures and marine life at risk. Skjeldam supports more regulation—to a certain extent, he says, such measures to limit cruise industry pollution are inevitable.
UK, France, Belgium: Travel strikes planned for April and May
To reduce air pollution from cruise ships, some countries have implemented regulations that require ships to use cleaner fuels and technologies. According to a study published in Science Direct, the emissions from cruise ships in the port of Naples, Italy, impacted the air quality of the surrounding areas. Even if companies don’t get on board with building more sustainable cruise liners, they can start with building smaller cruise ships in general. As of right now, the average cruise ship can accommodate around 3,000 people – but major cruise ship companies are seeking to build cruise ships which can hold triple the amount of passengers.

They instead rely on marine gas oil, which contributes to local air pollution, or liquefied natural gas (LNG), which has lower air pollutants but leads to some methane being emitted into the atmosphere. A report released earlier this year by the Brussels-based NGO Transport & Environment detailed that Europe’s fleet of 218 cruise ships emitted as much sulfur oxide in 2022 as a billion cars. Meanwhile, in the United Kingdom, local environmental groups have demonstrated that a single cruise ship can emit as much pollution as 700 trucks and as much particulate matter as a million cars. It has been estimated that between 40,000 and 100,000 Britons die prematurely every year as a result of emissions from the shipping and cruise industries, with major port-cities such as Southampton, Grimsby and Liverpool particularly affected.
"Waste heat recovery systems are allowing ships like those in the Disney Cruise Line fleet to reduce water usage," the outlet added, and "many cruise lines are also making investments in big-picture sustainability efforts." Norwegian cruise line Hurtigruten has said it will no longer build fossil fuel-based ships, and is attempting to craft the world's first zero-emission liner. The ship will operate on batteries that "would allow it to run for well over 300 miles before recharging," Time reported. The US public health agency lowered its pandemic travel warning for cruise ships last week, from “very high” to “high”. Clia has announced this after a recent Channel 4 investigation where Dispatches scrutinised the pollution and various waste levels of cruise ships.
This reveals how disproportionately bad for the environment cruise ships are, releasing the highest amount of black carbon per ship of any vessel. Container ships, on the other hand, produce around a third of the black carbon per ship, at only 3.5 tonnes. But with so many of them (5008 according to the cited 2017 report, or 5,534 according to our latest stats), they have a far greater impact on the environment, accounting for 26 percent of the global fleet’s black carbon emissions.
Sulfur mixed with air and water forms sulfuric acid, which is the main ingredient in acid rain. This can destroy marine life, corrode buildings, and cause deforestation. The International Maritime Organization says that all ships must switch to cleaner fuel with lower sulfur content by this year—but the solution still isn’t too effective.
Royal Caribbean’s pollution is second only to Carnival Corporation when it comes to the criminal fines they’ve had to pay. They were forced to pay $18 million in fines for 21 federal felonies in 1999 due to dumping hazardous chemicals and waste oil in coastal waters. Coast Guard and Justice Department by falsifying oil logs to cover up their crimes. The report recommended that Europe implement a zero-emission port standard, in addition to extending emission control areas (they are only in the North and Baltic Seas and the English Channel) to the remainder of the European seas. In 2021, Hurtigruten’s MS Fridtjof Nansen was voted the most sustainable ship in the world by Scope ESG Analysis due to its battery-hybrid technology.
The data collected reveals that standing on the deck of a cruise ship is similar to being in one of the world’s most polluted cities, with health experts warning of the issues surrounding poor air quality. According to a study conducted on Southampton, cruise ships can discharge untreated oily bilge water, which can damage marine life and ecosystems. If the separator, which is usually used to extract oil, is faulty or deliberately bypassed, untreated oily bilge water could be discharged directly into the ocean. It probably won’t come as a shock that the whole thing isn’t exactly sustainable. And for years, the industry has been dogged by bad PR from everything from routine dumping of toxic sludge to increasingly organized outrage from communities tired of hordes of tourists getting dumped at their docks. One of the key aspects of the shift is an attempted move toward alternative fuel sources.
In the sewage treatment category, which looks at whether sewage and greywater treatment systems are used or if sewage is dumped directly into the oceans, none of the companies scored above a C grade. Some climate activists say there’s a good argument that the cruise industry shouldn’t exist at all. Cruise ships are, on the whole, basically inherently wasteful—if you want to see the world, dragging an entire resort around with you is probably not going to be the most efficient way to do it.
