Ocean-going member cruise lines of Cruise Lines International Association (CLIA), the largest cruise industry trade association, have committed to reaching net-zero carbon emissions by 2050, and to reducing carbon rates by 40% by 2030 (as compared to 2008 levels).
But just how severe is their impact on the climate? Unfortunately, taking a cruise takes a toll on the planet. Your trip will average anywhere from 700-1000 pounds of carbon emissions a day, which is much higher than flying, driving or a traditional 'land' vacation.
A June study from sustainable transport campaigner The European Federation for Transport and Environment found that 63 cruise ships owned by parent company Carnival Corporation emitted 43% more sulfur oxides, a group of harmful air pollutants, than all the 291 million cars in Europe in 2022.
Augment this with no dumping solid waste at sea, (e.g. ground glass, cardboard and packing material, plastic), no discharges of hazardous chemicals or materials of unknown environmental impact (e.g., incinerator ash, sludge from smokestack scrubbers), and on all cruise ships have independent human monitors to observe ...
Cruise Ship PollutionAlthough cruise ships make up only 1 percent of the global fleet, they account for 6 percent of black carbon (BC) emissions. This reveals how disproportionately bad for the environment cruise ships are, releasing the highest amount of black carbon per ship of any vessel.
Common Features of Eco-Friendly Cruise Lines Include:Waste reduction and management: such as composting, recycling, and proper disposal of hazardous materials to minimize waste and pollution. Water conservation: such as using treated greywater for non-potable purposes and reducing water usage through efficient systems.
Cruise ships are only permitted to release human wastewater that has been heavily treated. Solid waste is also treated and dehydrated but not released into any open body of water. Instead, it is disposed of through standard, onshore waste disposal methods once the cruise ship is in port.
Yes, many cruise ships dump plastic at sea. It's illegal according to U.S. and international maritime law, but many companies have proven they don't care, and have been caught illegally spewing plastic into the sea. Carnival Cruise Lines was found dumping food mixed with plastic waste into the waters of the Bahamas.
During a typical one-week voyage, a large cruise ship (with 3,000 passengers and crew) is estimated to generate 210,000 US gallons (790,000 L) of sewage; 1 million US gallons (3,800 m3) of graywater (wastewater from sinks, showers, and laundries); more than 130 US gallons (490 L) of hazardous wastes; 8 tons of solid ...
Cruise ships can harm coral reefs. Pollution from cruise ships can threaten coral reefs. Cruise ships can also damage reefs through collisions and anchors. Recent studies have linked coral diseases to human sewage not unlike what is released from cruise ships.
“Cruising is less stressful and also means you do not lose time commuting and travelling to a destination as you will be eating, watching shows, drinking with friends and sleeping in comfort as the ship takes you to the next destination. It is a more efficient and enjoyable use of your time.”
