Silversea Cruises - Final Grade: "D"
Silversea Cruises was founded in 1994. Headquartered in Florida, Silversea describes itself as a luxury cruise line that operates nine cruise ships worldwide. The Silversea cruise ship fleet consists of smaller ships with carrying capacities between 170 and 910 passengers and crew.
Of Silversea’s nine ships, only the Silver Shadow, the Silver Muse, and the Silver Spirit have installed advanced sewage treatment systems, resulting in a grade of D for the company’s 33 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. From 2011 to 2018 Silversea chose to discharge sewage from the Silver Shadow outside of Alaskan waters, thereby avoiding Alaska’s strong water quality standards. However, the Silver Shadow did not receive any violations when it did discharge in Alaskan state waters in 2010, earning Silversea a 100 percent for water quality compliance in Alaska.

Grading Methodology For The 2019 Cruise Ship Report Card
Friends of the Earth’s Cruise Ship Report Card ranks 16 major cruise lines and 185 cruise ships — Carnival Cruise Lines, Celebrity Cruises, Costa Cruises, Crystal 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 and Silversea Cruises—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 against the total number of ships in the cruise line.
. 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 only utilize low sulfur fuels continuously at levels lower than required by international and U.S. law. Use of scrubbers was no longer 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.
. 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 2018. Ships were given an ‘N/A’ if they traveled to Alaska but avoided Alaska’s strong water quality standards by discharging outside of those protected waters or if they didn’t travel to Alaska at all.
. To determine the Transparency grade for each cruise line we graded each line based on whether it responded to our 2019 requests for information regarding their environmental practices.
. All seven Carnival Corp. companies graded on the report card committed criminal environmental violations in 2017 and 2018 while on federal criminal probation in the US for violations dating back to 2005.
. The grades for each of the four criteria were averaged to calculate the Final Grade for each cruise line. Carnival Corp. companies have all received an overall F grade on this year’s report card due to their ongoing criminal behavior from every line under the Carnival brand while on federal probation in the US.

**For the 2019 Cruise Ship Report Card, we graded 16 cruise lines and the 185 cruise ships of those 16 lines operating around the world. All ocean-going cruise ships over 100 passengers and crew 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.
