Tell Costco and Walmart: Come Clean on Toilet Paper

Big box retailers Costco and Walmart refuse to say whether they profit from using a Canadian pulp mill that relies on the clearcutting of wildlife-rich, climate-critical forests, and that is actively worsening a mercury poisoning crisis.
NRDC found evidence linking their store-brand paper products to the Dryden mill. When NRDC reached out to both companies about this, neither company disclosed whether products sold through their stores may contain pulp from the facility. This raises concerns about transparency, traceability, and accountability in their tissue supply chains.
It's a troubling silence from companies whose Kirkland Signature and Great Value paper products already earned an F on NRDC's sustainability scorecard for their heavy reliance on forest fiber and lack of recycled content.
The mill's mercury crisis has devastated Grassy Narrows First Nation Indigenous community for generations. In the 1960s, it dumped untreated mercury into the local river, poisoning the community's food and its people. The mill no longer dumps mercury directly, but its wastewater interacts with existing mercury in the environment, converting it into an even more toxic form. A recent study shows it's doubling mercury levels in local fish.
This is part of a bigger fight: NRDC has pushed the tissue industry for years to stop destroying the Canadian boreal forest, and it's working. Kimberly-Clark has pledged to eliminate natural forest fiber from its products, Georgia-Pacific relaunched a recycled tissue line, and Procter & Gamble earned its first-ever B grade for a product using more sustainable bamboo fiber.
Now it’s time to put this same pressure on Costco and Walmart.
The Dryden mill’s pollution and Indigenous rights violations must end, and companies sourcing its materials must take action. Sign NRDC's petition urging Costco and Walmart to disclose any connection to the Dryden mill — and if one exists, to cut ties.
