BALTIMORE — In the third edition of Greenpeace’s recently released seafood sustainability scorecard, Carting Away the Oceans, more than half of the leading supermarket chains in the U.S. have now made some sign of progress in increasing the sustainability of their seafood operations.

The supermarket chain Wegmans received top ranking followed by Ahold USA (known locally as Giant), while Whole Foods dropped to third place from its December 2008 first place ranking. Safeway finished out the top five and Super Fresh, owned by A&P;, held the 12th spot.

Of the 20 largest retailers in North America, nine remain that have made no visible effort to increase the sustainability of their seafood operations and continue to ignore scientific warnings about the crisis facing global fisheries and the marine environment. These include: Aldi, Costco, Giant Eagle, H.E.B., Meijer, Price Chopper, Publix, Trader Joe’s, and Winn Dixie. Despite the progress of many companies, all continue to stock “red list” seafood like orange roughy, swordfish, or Chilean sea bass — some of the world’s most critically imperiled species. None of the companies featured in the report guarantee that they won’t sell seafood from fisheries that are harming sea turtles, dolphins, seals, sea lions, or other marine mammals.
