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.


TUI Cruises

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. 

Mein Schiff 4

TUI Cruises "Mein Schiff" newbuilds are setting new standards in the cruise sector. With the use of intelligent energy management and light control systems it is possible to save large amounts of fuel - up to 10 tons a day. Also the increased utilization of the engines thermal discharge, modern waste treatment, streamlined hulls and low-friction and ecofriendly silicone paint help to improve efficiency.

Hybdrid Scrubber
Exhaust gas treatment

Advanced exhaust gas purification and selective catalytic reduction work together to cut sulphur emissions by up to 99 % and particle emissions by 60 %. The catalyst reduces nitrogen oxide emissions by 75 % to the tier III value. This puts Mein Schiff 3 and 4 ahead of the game, as these requirements are only now binding for cruise ship newbuilds from 2016.

Hapag-Lloyd Cruises 

The ships of Hapag Lloyd Cruises are also equipped with modern eco-technologies like sea water desalination systems for drinking water, biological sewage treatement, anti-fouling silicone paint and high-tech waste-to-energy plants.

MS Europa 2

"The best ship in the world" , according to the Berlitz Cruise Guide 2016, hosts up to 500 passengers on its luxurious voyages. Launched in 2013, the MS Europe 2 was the first cruise ship equipped with selective catalytic reduction (SCR). This catalyst takes out over 75% of sulphur from the exhaust gases and reduces the nitric oxide-emissions by up to 95%. Therefore it was the first EEDI certified (Energy Efficiency Design Index) cruise ship by the Germanischer Lloyd SE.

Hapag Arktis
Polar regions

As a member of the International Association of Antarctica Tour Operators (IAATO), Hapag-Lloyd Cruises also observes their guidelines on all Arctic and Antarctic voyages. In order to protect the sensitive polar waters, our cruise ships use diesel rather than heavy oil. Sensitising customers and crews and using efficient on-board technologies, Hapag-Lloyd is working to enhance the environmental compatibility of cruises.

For unavoidable emissions, Hapag-Lloyd Cruises offers its customers the opportunity to offset carbon emissions from the cruise. A climate calculator has been devised in cooperation with the German organization atmosfair. It checks various parameters, e. g. cabin category and length of stay on board, and subsequently determines the climate footprint of the cruise. Hapag-Lloyd Cruises uses the offsetting contributions to support a project in India, providing solar lamps in rural areas.

Marella Cruises

Marella Cruises is the UK’s third largest cruise line, carrying 250,000 passengers per year. It operates five cruise ships in destinations including the Mediterranean, Canaries and Caribbean.

The company has introduced a wide range of more efficient procedures and technology including single engine running, or drifting on passage, where speeds allow; so that the engines can run at their most efficient speed and installing new equipment on board, from the laundry to air conditioning plant – cutting the demand for energy produced by the ship.
