3.3.1. Ship Emissions
Ship’s engines have negative effects with their pollutant emissions on environment. Amount of pollutant
emissions of cruise ships will be increased % 72 until 2020 according to International Maritime Organization. These
ships are mostly compared with small cities. They leave ecological footprint in the water while they use rest
production of oil refineries during the journey. Soot-, SOx- (Sulfurdioxide) und NOx- (Nitrogen oxides) –
Emissions are most important reasons for climate and health problems. Ship gases have these harmful substances
which can create heart and liver illnesses. Especially crew members and locals of coastal regions live under big
treat. There is a great need of law in order to decrease the level of harmful emissions which cover especially cruise
ships. Since 2010, in some regions such as Baltic Sea, there is a restriction for cruise ships that they cannot be operated with more than 1 % of sulphur content. Next year, it is only possible to move with maximum 0.1% of
sulphur content. These regulations are not applied worldwide. Diesel costs will increase and this will have negative
effect on tickets per person.
