Silversea Cruises - Final Grade: "F"
Silversea Cruises was founded in 1994 and in 2020 became a fully-owned subsidiary of Royal Caribbean Group (RCG) which is incorporated in Liberia. Headquartered in Monaco, Silversea describes itself as a luxury cruise line that operates 11 cruise ships worldwide. The Silversea cruise ship fleet consists of smaller ships with carrying capacities between 200 and 1,050 passengers and crew.
Of Silversea’s 11 ships, seven have installed advanced sewage treatment systems, resulting in a grade of D for the company’s 38 percent sewage treatment score. In total, none of Silversea’s ships have shorepower capability, earning the company an F in this category. Silversea operated one ship, the Silver Shadow, in Alaska from 2010 to 2018 and another ship, the Silver Muse, in 2019. Neither the Silver Shadow nor the Silver Muse received any violations when operating in Alaskan state waters. Two of Silversea’s ships have scrubbers installed. Together these factors give Silversea a C- for water quality compliance since scrubber use merely converts air pollution into toxic water pollution.

Grading Methodology For The 2022 Cruise Ship Report Card
Friends of the Earth’s Cruise Ship Report Card ranks 18 major cruise lines and 213 cruise ships — AIDA Cruises, Carnival Cruise Lines, Celebrity Cruises, Costa Cruises, Cunard Cruise Line, Disney Cruise Line, Holland America Line, MSC Cruises, Norwegian Cruise Lines, Oceania Cruises, P&O Cruises, Princess Cruises, Regent Seven Seas Cruises, Royal Caribbean Int’l, Seabourn Cruise Line, Silversea Cruises, Viking Cruises, and Virgin Voyages — according to four environmental criteria: Sewage Treatment, Air Pollution Reduction, Water Quality Compliance and Transparency.
To determine a cruise line’s Sewage Treatment grade, we compared the number of cruise ships in the cruise line that have installed advanced sewage treatment systems (AWTS) against the total number of ships in the cruise line. Ships with AWTS have been downgraded from As to Cs since 2020 because no companies publicly report on the performance of those advanced systems.
Air Pollution Reduction
To determine the Air Pollution Reduction grade for each ship in a cruise line, ships that dock at a port and plug in to available shoreside power hookups were graded. In addition, ships were given credit if they utilize low sulfur fuels continuously worldwide at levels lower than required by international law. Use of scrubbers is not considered since the significant majority of scrubbers in use by the cruise industry simply convert air pollution emissions into water pollution through their scrubber wastewater discharges.
Water Quality Compliance
To determine the Water Quality Compliance grade for ships operating in Alaska, we used notices of violation issued for individual cruise ships to each cruise line by the Alaska Department of Environmental Conservation from 2010 to 2021. We also failed ships for their scrubber use since scrubbers convert air pollution emissions into water pollution.
To determine the Transparency grade for each cruise line we graded each cruise line based on whether it responded to our 2022 requests for information regarding their environmental practices. Companies that responded with specifics were given As, those that didn’t received failing grades.

**For the 2022 Cruise Ship Report Card, we graded 18 cruise lines and 213 cruise ships of those 18 lines operating around the world. All cruise ships from each cruise line were included in this report card. Friends of the Earth relied on data gathered from the internet, government sources, the cruise line industry, and other public sources in order to determine the grades assigned to the cruise lines. Friends of the Earth did not independently verify that the technology graded in the report card was installed on the individual cruise ships.
