If the pollution from cruise ship is released without
proper treatment, these wastes can put pathogens, nutrients, and toxic
substances into the environment that could threaten human health and aquatic
life. They may also have an outsized effect on the subset of ports and coastal
areas that see much cruise-ship activity. The pollution from ships has been
accelerating as trade has become increasingly globalized, posing an increasing
threat to the worlds oceans and waterways as globalization continues. In one
week, a typical cruise ship generates 210,000 gallons of black water (sewage),
1,000,000 gallons of gray water (shower, sink, dishwashing water), 37,000
gallons of oily bilge water, more than eight tons of solid waste, millions of
gallons of ballast water containing potential invasive species, and toxic wastes
from dry cleaning and photo processing laboratories.

Pollution from Cruise ships are a growing problem. New rules can stop pollution cruise ships from entering the fjords in Norway the next years.
Cruise ships and other large marine vessels have diesel engines, big as houses, that are major sources of air pollution. One cruise ship discharges 1/5 tons of smog-forming nitrogen oxides, 1.3 tons of sulfur oxides (the equivalent of a large cement plant), 253 pounds of carbon dioxide, 100 pounds of volatile organic compounds, and 75 pounds of particulate matter.
While in port, the cruise ships spew diesel exhaust by the ton when running on-board air conditioners and refrigerators. An average cruise ship produces as much air pollution as 12,000 or more cars in a single port visit, according to the Monterey Air Pollution Control District.
In some of the small towns along the Norwegian fjords this has been a large problem the last years. According to an article in the Norwegian newspaper Aftenposten 14.06.2006, results from calculations done by the Norwegian Institute for Air Research show that one of Norway's most popular tourist destinations, Geiranger, often featured in promotional materials, can have air quality that's on par with London or Glasgow.
Some days, when maybe four or five cruise ships have sailed into the narrow Geirangerfjord, the concentration of nitrogen dioxide is at about the same level found in such cities as London, Glasgow, Barcelona, Munich and Oslo. The main reason to this major problem in Norway is that there are many old cruise ships, with engines that operates on heavy oil, that traffics the Norwegian cost and fjords in summertime.
The Norwegian minister of environment, Eirik Solheim calls the new rules a big victory for Norway, the cost and the environment. The problems with air pollution from cruise ships will be gone before 2020 he claims. This year as much as 177 cruise ships are expected to Geiranger. The new rules gives the government permission to stop cruise ships that pollutes sailing in Norwegian fjords. According to Norwegian news today Solheim also predicts the future, saying These ships will also be stopped in other harbours around the world. In practice this means that such ships will disappear, meaning that old ships that pollutes a lot will have no places to sail.
And for those wondering - there are other good reasons to make these new rules remember that the Norwegian fjords are quite unique. The Geiranger Fjord for instance, tops the list of the 10 best sites in Scandinavia, according to the "Lonely Planet" travel guide. And that, according to "Lonely Planet," includes sites in Finland, Iceland, Greenland and the Faeroe Islands as well. And both the Geirangerfjord and the Nζrψyfjord have since 2005 been on the United Nations' "World Heritage" list.
But what about tourist that would like to visit the fjords. Founder of the internet site that gives tourists in Norway advices, Linn Haugen, gives the following advice :
Do not be afraid to ask your tour-operator about their cruise ship the age of it, and if they can guarantee that the ships engines not operate on heavy oil- for instance. If they can not give you an answer, ask if them to check it up and come back to you demand an answer. Give a thought to those living along the beautiful fjords, they would appreciate that their surroundings where just as beautiful and not destroyed by pollution in the years to come. And continue to visit us we like to share the beauty of Norwegian nature !
Yes, the new stricter Norwegian rules can prove to be the best for both residents along the fjords and the tourist.
