This can exacerbate ocean acidification, already ramping up with climate change, and directly impact ocean life, including fragile coral reefs, the council’s website states. Royal Caribbean has 25 ships in its fleet and 22 of them utilize scrubbers to get around community and climate-harming emissions. Scrubbers are used to “clean” smokestacks from the dirty fuel they use and reduce air pollution. But the scrubbers convert air pollution into water pollution because the toxic byproducts from the scrubber systems are discharged into the seas.
Direct Discharge of Waste
On top of the pollution caused by their exhaust fumes, cruise ships have been caught discarding trash, fuel, and sewage directly into the ocean. 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. The direct discharge of waste from cruise ships can also include untreated wastewater, which can contain pathogens, nutrients, and other contaminants. This wastewater can be harmful to marine life and ecosystems, and it can also contribute to the growth of harmful algal blooms.
Bilge water
Now, corporations are building billion-dollar cruise ships to hold more than 9,000 people. They’re doing everything they can to pack these floating cities full of tourists while polluting everything in their path. Last year, the German watchdog Nabu surveyed 77 cruise ships and found that all but one used toxic heavy fuel oil that the group described as “dirtiest of all fuels”. This came a year after the same watchdog blew the whistle on German cruise operators for failing to adhere to their own air quality safety standards. 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. The cruise industry transported over 26 million customers last year and was worth upwards of $117 billion in 2017.

Blackwater/ Sewage Pollution
This discharge of the ballast water from the cruise ships is a significant cause of cruise pollution. 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. Disney cruises came top of the Friends of the Earth report card with a B- overall. It received three A’s for air pollution reduction, water quality compliance, and transparency and a C for sewage treatment.
During their five-year probationary period an independent court-ordered monitor was required to examine its ships. A year later, Carnival had to pay another $20 million for environmental violations. And in January 2022, it paid another $1 million for failing to implement court ordered monitoring programs to attempt to ensure it doesn’t illegally pollute in the future. The cruise industry has deep pockets, yet giant cruise corporations continue to use the cheapest fuel allowed and do nothing to rein in their emissions and pollution.
Most polluted port cities and countries
In a study published in the Journal of Environmental Science and Pollution Research, it was found that oil spills can cause both short-term and long-term damage to marine ecosystems [3]. The study found that sulfur dioxide emissions from cruise liners were higher than other types of ships, and the emissions were highest when the ships were docked. 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.

A spokesperson for Carnival told Insider that the company is the only major cruise corporation with fewer greenhouse gas emissions today than in 2011, despite a forecasted capacity increase of 30%. As aerosol emissions fall due to new regulations, like the IMO's shipping fuel rule, that could speed up global temperature rise in the short term, as Dr. Robert Rohde, lead scientist at Berkeley Earth, explained in a Twitter thread on Wednesday. But the industry's tendencies of overconsumption extend beyond all-you-can-eat buffets and unlimited drink packages — and come at an environmental cost. But the journey to those pristine areas, which involves sailing along Canada’s west coast for two or three days, is leaving behind a trail of toxic waste, including within marine protected areas (MPAs), according to new research. For some time, campaigners have highlighted the dumping of sewage and wastewater as the face of an unsustainable cruise industry. Carnival was hit with a $40 million fine for illegal waste disposal and was put on federal criminal probation in 2017.
Aside from air pollution, cruise ships produce various waste streams, namely wastewater from sinks, showers, and galleys (grey water), hazardous wastes, solid waste, oily bilge water, and ballast water. Toxic air pollutants from cruise ships around ports are higher than pre-pandemic levels, leaving Europe’s port cities choking in air pollution, a new Transport & Environment study shows. Despite the introduction of the UN shipping body’s sulphur cap in 2020, last year Europe’s 218 cruise ships emitted as much sulphur oxides (SOx) as 1 billion cars. However, at the port of Venice air pollutants from cruise ships fell 80% following the city’s ban on large cruise ships. It shows that it is possible to tackle air pollution, says T&E, which calls for greater electrification at ports in order to save lives. According to a study conducted on Southampton, cruise ships can discharge untreated oily bilge water, which can damage marine life and ecosystems.

Some waste is incinerated onboard, so cruise ships generate ash and smoke containing toxic substances. Due to this waste treatment, toxic materials like polychorate biphenyls or PCBs, dioxins, and furans have been found in fuel from burning fuel. The noise the passing ships produce badly affects the environment as it disturbs the marine ecosystem. Unlike other ships, Cruise ships contribute heavily to marine noise pollution as the windows of noise pollution are high in cruise ships. Here are the significant ways cruise ships threaten the marine environment and contribute to global pollution. According to the Cruise Lines International Association (Clia), which comprises 95% of the global cruise industry, including 50 cruise lines and about 70,000 to travel agencies, 93% of the world’s oceangoing cruise liners are built in Europe.
According to Stand.Earth’s Barford, the vast majority — around 90% — of wastewater pollution in Canada’s waters is scrubber water. Canada’s newly mandatory regulations don’t touch scrubbers, she said, meaning they don’t address a large portion of pollution. Friends of the Earth works diligently to collect vital information about cruises to help the public understand their impacts. In our Cruise Ship Report Card we assess the largest cruise lines and their ships. Now that we’ve illuminated just how bad cruise ship pollution is, you likely aren’t going to be surprised when we tell you that cruise ship pollution is also worse than flying. Comparing mile to mile, the carbon footprint of a cruise is worse than an airplane.
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. 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.
However, Dídac Navarro, an activist from the organisation Ecologistas en Acció, says most passengers “just take a quick stroll then go back to the ship to eat and sleep”. Cruise ships are not held to the same important environmental protection standards that apply to cities and industries that produce a similar amount of waste. “Disney Cruise Lines is at the top of our report card, and would have received higher marks, but for the past two years we downgraded Disney for its push to build a massive cruise ship port at Lighthouse Point in the Bahamas,” says Keever. The eight cruise companies with criminal violations for a variety of illegal acts - such as dumping sewage and oil at at sea - are all owned by Carnival Corporation. “Carnival Corporation - the corporate parent for 10 major cruise lines including Princess, Holland America and Costa. Carnival Corp. is currently on federal criminal probation in the United States for environmental crimes,” says Keever.
This would prevent ships from hitting whales and also eliminate sonic disturbance to marine wildlife and coastal areas. The study also highlighted the role of cruise ships in spreading infectious diseases. This came to light at the beginning of the pandemic in 2020, when cruise ships such as the Diamond Princess became hotbeds for the virus.
