Greenpeace released its latest seafood sustainability campaign this morning and took aim at American grocery stores. Unfortunately, as we suspected it is merely another example of Greenpeaces failure to responsibly engage the seafood community in a constructive dialog about sustainability. Consumers should know that the retailer rankings presented in this report have no credibility. The non-science based standards by which Greenpeace came to its conclusions highlight the weaknesses in its efforts and undermine the entire project.
