FUEL & ENERGY EFFICIENCY | Exhaust Gas Cleaning Systems Cold-Ironing EXHAUST GAS CLEANING SYSTEMS One innovative technology our ships use to decrease exhaust emissions is an Exhaust Gas Cleaning System (EGCS). This technology reduces the amount of sulfur oxide (SOx) and particulate matter emitted from the ship by cleaning, or scrubbing, the emissions before they are released from the stack. Ships equipped with this technology are able to reduce SOx emissions by up to 99 percent. Ninety-one percent of systems installed on our ships can operate in open or closed-loop, which is known as a hybrid system. This allows the ships to operate the systems within compliance in expanded areas of the world.

Less than one percent of the ports we visit have installed infrastructure for cruise ships to connect to onshore electrical power grids to supply much of the power needed while docked-a process known as cold-ironing. Several Norwegian Cruise Line's ships are equipped with cold-ironing, also referred to as shore power, and we are continuing to evaluate the availability of shore-power connections for future new builds and itinerary planning.
