Best And Worst Sustainable Seafood Supermarkets (PHOTOS)

Greenpeace has released the fourth update of their Carting Away the Oceans report, where they give us the latest review of the best and worst sustainable seafood supermarkets for 2010. In an effort to push for an environmentally friendly and sustainable seafood marketplace, Greenpeace has done an in-depth ranking of 20 popular seafood retailers, rating them on factors like their seafood policies, initiatives in sustainability, and the quality of their labeling in providing consumers concise and accurate information about the seafood they purchase. Greenpeace also makes note of how many species each company sells that are on Greenpeace's red list, a list compiling the 22 most unsustainable seafood products on the market.

Greenpeace gives each grocery chain an overall rank from 1-10. 1-3 is a failing grade, 4-6 is passing, and 7-10 is good. Though no one has yet reached that highest division, 10 of the 20 companies reviewed made a passing grade, with many taking audacious strides to improve their previous scores, and setting new precedents in the marketplace for sustainable seafood.

Take a look at how Greenpeace rated popular chains like Target, Wal-Mart, Costco, Trader Joe's, and others. Vote to let us know which rating surprised you the most! Read Greenpeace's report for more information.
