CLIA Global Oceangoing Cruise Lines - August 2022

This table provides aggregated data across CLIA’s global oceangoing cruise line membership. The table reflects the number of ships equipped with certain technologies, corresponding passenger capacities (lower berth at double occupancy) and the percentage of the entire fleet represented.

Oceangoing Ships Reporting

241

555,635

95.9%

Cruise lines continue to transform the modern fleet to protect the oceans, air and destinations enjoyed by millions of passengers each year.

CLIA’s Waste Management Policy is available here. Each year, cruise line CEO’s verify implementation as a condition of membership. The Policy is incorporated into each ship’s Safety Management System (SMS) and is subject to third party and internal auditing.

Additional environmental reports, including third party research on air and waste water performance, are available here. Many individual cruise line sustainability reports are publicly available on company websites.

EXHAUST GAS CLEANING SYSTEMS (EGCS)

Ships fitted with exhaust gas cleaning systems (EGCS)

152

439,046

79.0%

EGCS systems remove 99% of sulfur & well over 50% of particulate matter, including elemental & organic carbon. Catalytic filter & other systems further reduce particulate matter by over 30% & reduce nitrogen oxides by up to 12%.

Existing & forecast EGCS installations are for hybrid or open loop systems and many include wash water filters. Some include a catalytic filter on the engine exhaust prior to the EGCS, as well as continuous monitoring equipment to automatically record all parameters. A variety of technologies further clean the EGCS wash water stream including fine-mesh filtration, purification, centrifugal separation & dissolved air with flocculant. EGCS wash water filter residue & process tank residue are disposed of ashore.

Additional information on EGCS performance is available here and here.

Many cruise ships are equipped to operate on both biodiesel and traditional fossil fuels. Cruise lines are investing in pilot projects aimed at developing sustainable marine fuels including biofuels and synthetic fuels to operate, where possible, with existing ship systems.

Several companies are exploring fuel cell and equivalent technologies for future new builds or retrofit projects.

Ships use Marine Gas Oil (MGO) in many regions to comply with IMO ECAs (North America & Caribbean Sea, North Sea and Baltic Sea), EU Mediterranean Sea ports, the Arctic, China’s emission control area, Australian ports and to meet other locally imposed requirements. Ships may also use Very Low Sulphur Fuel Oil (VLSFO) or Ultra Low Sulphur Fuel Oil (ULSFO) in these regions to comply with emissions requirements. Ships fitted with EGCS will generally use this equivalent technology unless its use is not permitted and will use MGO where specifically required. CLIA Members have also committed to not burn HFO in the Arctic ahead of the IMO use and carriage ban.

WASTE WATER

Ships that have an advanced waste water treatment system on board, approved, used and capable of meeting or exceeding IMO MARPOL Annex IV discharge norms

182

434,070

78.1%

Many ships are equipped with advanced waste water treatment systems (AWTS) that are capable of exceeding MARPOL Annex IV requirements and are operated to meet or exceed the more stringent sewage discharge criteria in Alaskan waters and/or the Baltic Sea Special Area, as well as gray water requirements under the U.S. Vessel General Permit (VGP).

CLIA Member Lines recognize the extraordinary eutrophication situation in the Baltic Sea. CLIA supports the special area requirements for MARPOL ANNEX IV waste and works with the local and regional authorities for its success, including the existing commitment to provide adequate Port Reception Facilities.

By CLIA policy, bio-residual from advanced waste water treatment systems may be landed ashore, dried and incinerated or discharged at sea in accordance with MARPOL Annex IV when the ship is more than 12 nm from nearest land while moving at a speed greater than 4 knots.

New build ships that will have an advanced waste water treatment system on board, approved and capable of meeting or exceeding IMO MARPOL Annex IV discharge norms.
