Cruise Ships
We advocate for laws and regulations to stop cruise ships from dumping waste into our oceans, polluting our beaches, contaminating our coral reefs, and destroying our valuable marine ecology.
Cruise ships the size of small cities ply the waters off our coasts, producing and then dumping large amounts of sewage and other wastes into our oceans, polluting our beaches, contaminating our coral reefs, and destroying our valuable marine ecology. Some of that waste is treated prior to dumping; other waste is dumped directly to the ocean without a second thought.
A large cruise ship, the largest of which can carry over 7,000 passengers and crew, on a one week voyage is estimated to generate 210,000 gallons (or 10 backyard swimming pools) of human sewage and 1 million gallons (40 more swimming pools) of graywater (water from sinks, baths, showers, laundry and galleys). Cruise ships also generate large volumes of oily bilge water, sewage sludge, garbage and hazardous wastes. In addition, these luxury liners, which allow passengers a rare glimpse of some of the most sensitive environments on the planet, spew a range of pollutants into the air that can lead to serious public health problems and contribute to global warming.
The rapidly expanding size and number of cruise ships in U.S. waters has triggered a national cruise ship pollution crisis. Environmental laws have not kept pace with growth of the industry. Cruise lines travel the most pristine waters of America, dumping all the way. New laws and standards are urgently needed.
Choose A Greener Cruise
Our Cruise Ship Report Card lets vacationers decide which cruise to take based on a cruise ship or cruise line’s environmental and human health impacts.
Cruise Line |
Sewage Treatment
Sewage Treatment Has the cruise line installed the most advanced sewage and wastewater treatment systems (AWTS) available instead of dumping minimally treated sewage directly into the water? In determining a cruise line’s Sewage Treatment grade, we compared the number of cruise ships in the cruise line that have installed advanced sewage treatment systems against the total number of ships in the cruise line. Ships with AWTS were downgraded in 2022 because no companies publicly report on the performance of those advanced systems. |
Air Pollution Reduction
Air Pollution Reduction Has the cruise line installed shorepower or adopted cleaner fuel worldwide? In determining the Air Pollution Reduction grade for each ship in a cruise line, ships that dock at a port and plug in to available shoreside power hookups were graded. In addition, ships were given credit if they utilize low sulfur fuels continuously worldwide at levels lower than required by international law. Use of scrubbers is not considered since the scrubbers in use by the cruise industry simply convert air pollution emissions into water pollution through their scrubber wastewater discharges. |
Water Quality Compliance
Water Quality Compliance To what degree did cruise ships violated water pollution standards designed to better protect the Alaskan coast. In determining the Water Quality Compliance grade for cruise ships, we used notices of violation issued for individual cruise ships to each cruise line by the Alaska Department of Environmental Conservation from 2010 to 2021. In addition, we downgraded ships for their use of scrubbers since scrubbers convert air pollution emissions into water pollution. |

2022 Final Grade
**For the 2022 Cruise Ship Report Card, we graded 18 cruise lines and 213 cruise ships of those 18 lines operating around the world. All cruise ships from each cruise line were included in this report card. Friends of the Earth relied on data gathered from the internet, government sources, the cruise line industry, and other public sources in order to determine the grades assigned to the cruise lines. Friends of the Earth did not independently verify that the technology graded in the report card was installed on the individual cruise ships. |
