Marella's newest ship in the fleet - the Discovery
Apart from greenhouse gas emissions, TUI's cruise companies also seek to reduce harmful air-borne pollutants such as sulphur oxides, nitrogen oxides and particles (soot). To this end, the cruise companies continually implement both operational and technical measures.
The TUI Cruises fleet was extended by newbuilds in 2014 and 2015 and currently operates four vessels. Two more ships are in the making and another two have already been ordered. The "Mein Schiff 3 and 4" are specifically designed to be more energy-efficient. This means they burn up to 30% less energy, and therefore fuel than comparable sized ships.
