The dirtiest way to travel

of Course, there's nothing like candles without the Miracle. At the end of each episode of the ZDF-duration series "dream boat" come the sparklers, they stuck to pies, layered desserts or fruit salad, and they are the unmistakable signs that all is finally well again.

The reality is considerably less glamorous, especially under environmental protection aspects, cruise ships are a floating Disaster: A single ship blows every day, so much Dirt in the air as 400'000 in PW, at least. Some environmental organizations to set the value even higher.

in addition, the Boom in the cruises remains without consequences for the visited cities. The inhabitants in the coastal places are annoyed, in Venice, the Unesco even feared damage to the world heritage site by the huge masses of tourists that flock from the cruise ships to the center: Always the same way, always the same sights, the same Selfies, and then quickly back on Board. Cruise ships are on the way to become the icon for the worst Form of the tourism , to travel for the dirtiest kind.

nightmare ahoy

This lack of sustainability is a Problem, not only from the point of view of people who care about the environment. It is also a Problem from the point of view of shipping companies. With the Geneva-MSC Cruises, one of the leading Player sits in Switzerland. Image difficulties for your floating money machine can not make use of the growth-drenched industry. Therefore, cruise ships should be clean – before your target audience gets a guilty Conscience.

According to the industry Association Clia, probably to check in this year for the first time, more than 30 million guests on one of the floating palaces. In Europe, Switzerland is still the sixth-largest market, with 151'000 pass in the year 2017. However, it should be more, because many of the Swiss book your trip abroad.

liquefied natural gas as a cleaner Alternative

The green flagship of the industry, the Aidanova the seas in December on the world. The ship, the sails 6600 passengers to the Canary Islands, is the first cruise ship, complete with the liquefied natural gas LNG is operated. With this drive technology, the ship is still far from it, to enable ecologically friendly cruises, however, it is a big step to more environmental protection . The Geneva-based MSC has ordered the French STX shipyard in new ships, which will also be LPG. The newbuildings to be delivered in 2022 and 2024 and the 6850 passengers to accommodate what would be a new record.

Without a Filter on-the-go

Today, however, many cruise ships travel so far, not even with a marine diesel, but heavy fuel oil, so perhaps the dirtiest fuel of all. In a study published by the environmental organisation Nabu in the last summer, were at that time 76 of the investigated vessels, at least 61 even without a soot particle filter.

In Scandinavia, ferries, some Electric on limited routes in use it is Clear: The concern for the Image of the segment with the guests is advancing the efforts of the cruise lines, in addition to Aida, a number of other companies have ordered LNG ships. This in turn has consequences for the whole shipping industry.

ports under pressure

Many ports are gearing up now in a hurry, the supply of LNG to ensure – because what was once exotic Chi-Chi, is soon to be a competitive factor: Who will be able to fill any of the LNG ships will eventually not have any LNG vessels in its port. In the case of the Aidanova the shipping company has solved the Problem in a pragmatic way: A LNG filling enough to operate the ship for 14 days. The tours, for the Aidanova is used, at first, shorter Trips.

at the same time shipyards and shipping companies are struggling also to other alternative drive technologies. This year, the Norwegian shipping company wants to take Hurtigruten on the MS Roald Amundsen in operation – a hybrid ship. In addition to the diesel engine it has an electric drive, in addition, the body of smoke is designed to minimize. The bottom line is the Roald to shoot Amundsen as 20 percent less emissions than a comparable cruise ship.

Hybrid only for the short-distance

In a particularly emissions-sensitive areas of the ship over short distances is expected to operate without Diesel. This illustrates quite well where the electric technology in the case of ships currently In Scandinavia, some of the electric ferries are on limited routes. Of a cruise ship in the Dimension of a floating city small to be able to provide the technology, but a whole piece.

the same applies to container ships, which have similar or even more emissions responsible as cruise ships, but not pressured by the number of passengers who do not want to choose between environmental Conscience and a relaxed holiday There is, especially in Scandinavia, individual experiments with electric container transport on short distances, are also converted several freighters to LNG. To is industry-wide sustainability of the way but still far.

After all, by 2020, to apply stricter limits for sulphur in fuel, which is also less ambitious shipping companies forces, either from heavy fuel oil to marine diesel switch, or subsequently cleaning technology.

It is a layered dessert with a Sparkler.
