cross-boom rides: 28.5 million passengers were recorded in 2018 worldwide, including approximately 154’000 Swiss. The are 6.7 percent more than in 2017. That is not enough: The Boom should stop and 2020, even for the first time, the 30-million mark crack. Therefore, the industry plans in the next few years, nearly 120 new cruise ships.

However, just how eco-friendly the huge ships on our seas, anyway? The German nature and biodiversity conservation Union (Nabu) has published the end of August, 2019 an environmental Ranking for cruise ships. The conclusion of the conservationist: There are hardly any clean ships, and still shipping companies rely on heavy fuel oil.

the best Aidanova and the Costa Smeralda cut. They are the Only ones that are operated with liquefied petroleum gas. “Most of the ships continue with heavy fuel oil and avoid the use of exhaust-gas technology”, writes the German society for nature conservation on its website.

On the third place three ships of the shipping company Hapag-Lloyd: the Europa 2 and the two expedition cruise ships Hanseatic Nature and Hanseatic Inspiration to land.

“Tragic,” the conservation Covenant, the liquefied gas, the Aidanova and Costa carried Smeralda on place 1 in the Rankings, not a very eco-friendly. In fact, the Gas is a fossil fuel and has, according to various studies, the same impact on the environment such as Diesel. However, for comparison with the heavy oil that is the lower damage.

According to the Nabu, a large cruise ship that is powered with heavy fuel oil emits as much pollutants as five million cars on the same track.

climate protection as a new evaluation point

this year, was introduced in the environmental assessment in addition, the new category of climate (in addition to air pollution). In the case of climate technologies to be assessed in the area of the drives and the power supply. “Only two sailing ships and those ships have a shore-power connection, and through this their energy needs during the time spent in port with electricity from renewable sources, cut here is better than the other”, accounted for the nature conservancy.

Hurtigruten set with the hybrid ship Roald Amundsen “new standards, which will allow a gain in efficiency of the still diesel-electric drive, and thus a CO2-reduction”.

“out of date according to the industry”

The German nature of the Federal draws a bitter conclusion for the whole of the Ranking: “The industry is absolutely anachronistic and irresponsible. Also, many ships are today, with a decades-old technical Standard on-the-go. A scandal, because the comprehensive reduction of air pollutants is technically possible today.”

It was high time to install clean exhaust technology for all ships, and to make statutory provision for the entry into ports.
