They generate large amounts of waste, including sewage, gray water, and solid waste, which can contain harmful chemicals and pathogens. While minimal attention is paid to food waste management by many ships and catering typical of cruise liners, it can still have a significant impact on the environment. Food waste is another type of waste generated by cruise ships, and it can also be discharged directly into the ocean. The study also highlighted the role of cruise ships in spreading infectious diseases.
They’re becoming more fuel-efficient
Industry trade group Cruise Lines International Association (CLIA) has committed to net-zero carbon emissions by 2050. The vast ship has also been built to run on electricity supplied from shore when it is docked – a cleaner alternative to running highly polluting generators. Venice, Barcelona and Amsterdam are just three of the port cities to ban or curb cruise ships amid growing environmental and health concerns. Of the 264 ships in CLIA members’ fleets whose owners responded to a survey by the association, 202, or 76.5%, are equipped with advanced wastewater treatment systems (28 did not respond).
Scientists Find the Best Strategy for Tackling the Plastic Pollution in the Ocean
An environmental group called Friends of the Earth (FOE for short) writes a detailed “cruise report card” every year, ranking the big cruise companies from cleanest to dirtiest. The main types of pollution caused by ships are air pollution, water pollution, and noise pollution. Air pollution is caused by emissions from ship engines and includes sulfur dioxide, nitrogen oxides, and particulate matter. The program has implemented strict regulations for cruise ships to prevent oil spills and protect the environment [4]. According to a study published in the Journal of Marine Pollution Bulletin, cruise ships have the potential to contribute to accidental oil spills due to their large size and the amount of fuel they carry [1].
Carbon emissions are high—but they’re getting lower
Inevitably, more passengers means a higher carbon footprint per cruise – which is something for cruise ship companies to think about. Other efforts to reduce air pollution, such exhaust-gas cleaning systems, also known as scrubbers, can contribute to water contamination. Open-loop systems send the wash water directly into the sea, and it can be hot, highly acidic and contain a host of pollutants, including particulate matter, polycyclic aromatic hydrocarbons, and heavy metals. Closed-loop systems recirculate and continuously treat freshwater, collecting the resulting waste on board for later disposal on shore.
Is There Such a Thing as Sustainable Cruising?
Even without the risks of COVID, all that fuel can still lead to breathing in unhealthy levels of pollution. Researchers have found the air quality on cruise ships to be extremely poor due to the pollution these ships generate. The conditions are generally equivalent to living in a heavily polluted city. Many resort towns that welcome cruise ships have been directly affected by pollution from the vessels, and there has been a purported rise in medical problems in some of these areas.
Cruise Ship Report Card
Compared to flying to a destination and staying in a hotel, cruising almost always has a far higher emissions profile, according to research by Comer and others. A five-night, 1,200 mile cruise results in about 1,100 lbs of CO2 emissions, according to Comer. Flying the same distance and staying in a hotel would emit less than half of that. And that’s not counting for the fact that cruise guests often also have to fly to the port where they will embark. The big question, though, is whether those customers buying cruise packages to the Bahamas or Alaska particularly care. Other initiatives include onboard changes, and "most lines have reduced or eliminated single-use plastics aboard," Travel + Leisure noted.

If you keep up with the sustainable travel world, you know it’s sort of a trope to hate on big cruise ships. Water pollution from untreated sewage, gray water, and ballast water can harm marine ecosystems and contaminate local water sources. Water pollution is caused by discharge of untreated sewage, gray water, and ballast water, which can contain harmful chemicals and pathogens. Noise pollution is caused by ship engines, which can disrupt marine ecosystems and harm marine mammals.
In place of smokestacks, the designers envision retractable sails that double as solar panels. It runs on batteries instead of the thick, sticky fuel oil that powers most ships. Of the top cruise lines, Disney is open and transparent about their environmental impacts. Disney ships utilize fuel with a 0.1% sulfur content which is key to reducing climate-harming emissions. They like to provide their vacationers with a once-in-a-lifetime travel experience, including going to untouched areas of the planet and to create a “private island” experience. The industry also says it is committed to greener practices, with a target of net zero carbon cruising by 2050.

But he also has more faith that cruise-goers actually care about the environment than either activists or other cruise executives. And as the effects of climate change become more pronounced, he says, more of the world’s cruise-buying masses will begin to see the light. Trying to convince vacationers to make greener choices probably has limited effectiveness anyway.
Typically, a cruise ship will cost anywhere from 500 million to 900 million USD to build – with the average customer spending a few hundred for a short cruise ship vacation.

Cruise ships have often been described as ‘floating cities’, and as environmental groups have pointed out that they are just as if not more polluting. A passenger’s carbon footprint triples in size when taking a cruise and the emissions produced can contribute to serious health issues. On top of the pollution caused by their exhaust fumes, cruise ships have been caught discarding trash, fuel, and sewage directly into the ocean. But most of the US is way behind – maybe because everyone’s bickering over who should make the upgrades first.
But it could just be a green fluke, a new offering for a small slice of climate-conscious vacationers, as the rest of the industry chugs on as before. ‘Although a tiny fraction of the global maritime industry, cruise lines are leaders in implementing alternative fuels and emission-reduction technology,’ the company said. ‘Clia members have invested more than a billion dollars in technologies to minimise emissions and alternative fuel orders are in place for 87 cruise ships between 2017 and 2026.
‘Environmental sustainability is at the heart of the cruise lines’ economic models and it has been the absolute leader in the development and deployment of environmental technology innovations for decades. But with 87 ships due to be fitted or refitted with alternative fuel options until 2026, Clia stated the industry is likely to become much more environmentally minded. Coloured slides on its upper deck mark out “Thrill Island”, the largest waterpark at sea, and it boasts a 17-metre (55ft) indoor waterfall.
Celebrity Cruises is a subsidiary of Royal Caribbean Cruises Ltd., the world’s second-largest cruise line operator. Cunard Cruise Line is a subsidiary of Carnival Corp., the world's largest cruise operator. Holland America Line is a subsidiary of Carnival Corp., the world's largest cruise operator.
To comply with regulations put in place in 2020 under MARPOL that mandate emissions reductions, the industry is building new cruise ships that use alternative fuels, mainly liquefied natural gas (LNG). However, via a process known as “methane slip,” this fuel can also exacerbate emissions of this shorter-lived, but more potent greenhouse gas, according to research. At least one cruise company, though, is betting that at least some potential customers care about sustainable vacations. Hurtigruten, a specialty cruise line based in Norway, says it has built its last fossil fuel-powered ship. On June 7, the company unveiled new details about the technologies it’s testing in pursuit of the world’s first zero-emission cruise ship, and renderings of what the boat might look like. Instead of towering over the ocean, the ship seems to cling close to the water, the better to reduce air resistance.
The Dutch capital joins other cities, such as Venice in Italy, Monterey Bay in California, and Bar Harbor in Maine, in seeking to limit the impact of cruises. So those were the main environmental problems with cruise ships – dirty sewage, dirty fuel, and lots of ways for cruise ships to break the laws. But the problem is, if they just don’t apply for a permit, and dump their sewage further from shore, then they’re excluded from this grading category. These are delicate marine ecosystems that didn’t evolve to have tons of human waste dumped on them. When they’re dumped in the ocean, those nutrients and bacteria cause oxygen depletion, and toxic algae blooms – which cause ocean dead zones. And they spread bacteria and viruses, which means anyone eating seafood from areas where cruise ships have dumped can get sick.
