To tackle the issue, cruise ship owners are installing advanced wastewater treatment systems. The trade group represents the owners of 292 cruise ships, roughly 95% of the global fleet, according to Gill. CLIA member companies served roughly 30 million passengers per year pre-COVID-19. This article describes the several types of waste streams that cruise ships may discharge and emit. It identifies the complex body of international and domestic laws that address pollution from cruise ships.
Direct Discharge of Waste

In addition to the air and water pollution these cruise ships cause, Whales and Dolphins are also victims of the increasing traffic of these ships. These massive ships are responsible for injuring, often killing, marine lives, particularly fin whales, killer whales and humpback whales. It is estimated that cruise ships contribute 24% to the total solid waste generated by maritime traffic across the world as one of such luxury vessels can produce seven tons of garbage and solid waste in a single day. Classified under the head of the greywater, this water accumulation contains not just harmful chemicals but sometimes even metals and minerals.
Cleaning up waterborne waste
And however idyllic that sounds, there’s an environmental price to pay. In France, 10% of air pollution in the port city of Marseilles can be directly contributed to the shipping industry. Locals lament the increase in pollution and health issues with more luxury cruise liners docking in the harbor, and now environmental groups and the regional government are implementing emissions tests and issuing fines to the offending cruise lines.

The authors of the study, Josep Lloret, Arnau Carreño Hrvoje Carić, Joan San and Lora E. Fleming found that the industry also impacts human health, with those who live near ports affected by noise and air pollution. Though the IMO rule slashes the sulfur emissions of individual ships, it has done nothing to limit the increasing number of cruise ships in recent years. Compared to 2019, cruise ships are also spending more time at European ports and consuming more fuel, per the report.
Sewage Dumping from Cruise Ships
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. A quarter of all ocean waste comes from cruise ships, according to a recent study. Before the COVID-19 pandemic, the cruise industry was one of the fastest growing travel sectors, with passenger numbers rising steadily year-on-year.
What are some of the environmental impacts of cruise ships?
For decades, humans' emissions of sulfur and other aerosols have canceled out some of the warming from greenhouse gasses like carbon dioxide. CLIA states that around 150 ships in its members’ fleets are equipped with scrubbers, of which around one-third are open-loop systems. Their use will be phased out with the switch to new fuels such as LNG, Gill said. Port communities and passengers are stuck taking the brunt of this pollution. The emissions that passengers breath while on a cruise are over 20 times higher than on a busy, polluted roadway.

Cruise ships are notorious for utilizing the cheapest fuel on the market. They then use scrubbers to “clean” their smokestacks, and the pollutants are dumped directly into the ocean — warming the seas and poisoning marine wildlife. 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. Cruise ships contribute significantly to ocean pollution through the dumping of sewage waste.

Finally, these ships take in large quantities of ballast water, which is seawater pumped into the hulls of ships to ensure stability. This water is typically taken in at one port and then discharged at the ship's destination, which can introduce invasive species and serious diseases into U.S. waters. A medium-sized cruise ship uses about 150 tonnes of fuel daily, emitting as much particulate as one million cars. Cruise ships are a severe threat to coral reefs and their related organisms. As tourist vessels, the entry and anchoring of cruise ships on disturbed and undisturbed areas of coral reefs across the world have resulted in several incidents that involve the destruction of these natural wonders.
Cruise ship waste streams
The main shipyards for cruise ship construction are in Italy, Germany, France and Finland. Oceana is a non-profit international advocacy organization dedicated to protecting and restoring the world’s oceans through policy advocacy, science, law and public education. Founded in 2001, Oceana’s constituency includes members and activists from more than 190 countries and territories who are committed to saving the world’s marine environment. In 2002, the American Oceans Campaign became part of Oceana’s international effort to protect ocean eco-systems and sustain the circle of life. Oceana, headquartered in Washington, D.C., has additional offices in key U.S. coastal areas and will open offices in Latin America and Europe in 2003.
Avilés, whose district includes Red Hook, introduced the bill in February with the councilmember Erik Bottcher. We have already protected nearly 4 million square miles of ocean and innumerable sea life - but there is still more to be done. The company states that they have dedicated environmental officers on all of their ships and that they recycle more than 600 tonnes of metal, glass and plastic each year.
Accounting for all of its subsidiaries, the Carnival group polluted the most. In Folbert’s view, simply treating waste isn’t sufficient and companies must take a “broad perspective” on the variety and sources of pollutants to ensure adequate wastewater management. This means considering the fate of substances like microplastics, caffeine and pharmaceuticals that can escape treatment.
Unfortunately, as the cruise industry grows, so does the impact it has on the environment. Cruise ships can have a range of environmental impacts, including damage to marine ecosystems, harm to marine mammals, and contribution to climate change. To reduce the impact of direct waste discharge, some regulations have been put in place. However, there is still a need for more stringent regulations and enforcement to ensure that cruise ships do not cause further harm to the ocean and its inhabitants.
A few ships are testing these technologies and proving they work in Alaska, where the state applies the strictest laws in the country. The technology that works in Alaska should be installed on every cruise ship so that they can stop dumping raw sewage in our oceans. In July, Amsterdam became the latest in a series of cities to regulate against huge cruise ships in an attempt to tackle pollution and the burden of overtourism. 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.
The potency of greywater harming the marine environment is greater because of its high concentration in oceanic waters. Studies show that a large cruise ship releases around one million gallons of grey water during a single week’s voyage. In addition to the noise pollution from the ship’s machinery, cruise ships produce more noise thanks to the entertainment activities on board. These noises disturb the marine animals and mammals, including killer whales and dolphins, whose sensitive hearing gets harmed and debilitated, often leading to their unwanted death and an overall loss to the ecosystem.
Much of this rubbish is incinerated and disposed of at sea, putting countless sea creatures and marine life at risk. That did not however stop Italy from surpassing Spain as the most cruise ship polluted country in Europe. Although the Mediterranean bears the brunt of cruise ship pollution, Norway came fourth in the ranking and even had the highest cruise traffic of any country, albeit with smaller ships.
They are still traveling from port city to port city, polluting everything in their path. The untreated sewage contains harmful pathogens and bacteria that can cause health problems for marine life and humans. Slowly and steadily, even cruise shipping conglomerates have begun to understand the importance and necessity of preserving the marine ecosystem. For the time being, a better cruise shipping experience with the necessary caution and care for the aquatic life remains a dream to be realized and attained.
