Tell Costco to Stop Wholesale Ocean Destruction!


Everything about Costco is bigger than normal. Costco is the largest wholesale club operator in North America. People shop at Costco because of its bulk goods, low prices, and wide variety of merchandise. But, while Costco continues to grow bigger and bigger, so does its footprint on the environment.

In the Costco grocery warehouse you’ll find freezers and coolers full of unsustainable fish. Greenpeace surveys found that Costco continues to sell fourteen of the twenty-two red list seafood items.

Costco is enabling some of the most horrible seafood harvesting practices that are destroying our oceans. Many species of fish could die out if they're not conserved. Costco is not labeling its seafood properly, hiding the awful truth from its customers.

Whether or not you eat fish, one of the best ways we can take action to stop the destruction of our oceans is to target specific grocery store chains that are buying and selling red-list fish. If we can change these companies (and we have before!), we can help save the oceans.

Greenpeace urges Costco to implement a effective and publicly available sustainable seafood policy that creates transparency in its seafood labeling and prohibits the sale of red list species — starting now with Chilean sea bass. Other red list species from fisheries that are dangerously depleted must also be removed.

Sustainable seafood policies will reduce pressure on declining fish stocks and help heal our ailing oceans. Costco must use its massive buying power to leverage positive change in our oceans.

Tell Costco that our oceans deserve better.


Letter to
As a consumer, I care about what's being bought and sold at Costco. Our oceans deserve better. Costco needs to be a leader in ocean conservation, not a contributor to ocean destruction. I want Costco to have a sustainable seafood policy and stop selling red list seafood, starting immediately with orange roughy and Chilean sea bass.

Your customers want to know the truth. Stop hiding and let your customers make informed decisions about their purchases. I want Costco to have sustainable seafood and transparent labeling for all of us to see.

Costco must also begin to stand up for the oceans and support positive environmental change.
