The lawsuit, filed by Hagens Berman in the US District Court for the Western District of Washington, challenges Amazon's use of Marine Stewardship Council (MSC) certification, which it describes as operating on a "pay-for-play" basis. It alleges Amazon used terms like "sustainable" and "MSC Certified Sustainable Seafood" for products including its 365 by Whole Foods Market line, giving consumers a false impression of environmental practices. The complaint also claims Amazon breaches US Federal Trade Commission's Green Guides and Washington state consumer protection law, seeking consumer reimbursement and an injunction against these practices.
