Walmart, Target, and Costco:
Big box, big responsibility, big problem
Walmart, Target, and Costco — the Big 3 — have become some of the most powerful institutions in our daily lives. From seafood to baby food, their decisions shape what products are made, how they’re produced and packaged, and the impacts those choices have on people, communities, and the planet.
Yet too often, the true costs of doing business are borne by others. Pollution, plastic waste, toxic chemicals, environmental destruction, and labor abuses, including modern slavery, are not inevitable consequences of modern commerce—they are the result of business decisions.
These companies have the power to make better decisions. It’s time they were held accountable.
Human rights abuses and environmental destruction: Two sides of the same coin


Forced Labor and Destruction of Biodiversity
An estimated 128,000 fishers are trapped in forced labor aboard industrial fishing vessels. Many endure violence, debt bondage, dangerous working conditions, and months—or even years—at sea without a safe way to contact their families or seek help. The same conditions that enable labor abuses also fuel illegal, unreported, and unregulated (IUU) fishing, overfishing, and the destruction of ocean ecosystems. At least 76 to 80 million sharks were killed as a result of industrial fishing in just seven years. All three companies buy tuna sourced from vessels that catch fish using methods with high bycatch rates.


Plastic Pollution & Human Health
Plastic pollution contaminates our air, water, and food, while growing evidence links plastic chemicals and microplastics to risks for human health. Throughout their lifecycle—from fossil fuel extraction to disposal—plastics pollute our communities and ecosystems while accelerating climate change.
Why These Companies?
Walmart, Target, and Costco are among the world’s most influential retailers, with over $875 billion in combined annual sales. Through the products they sell, the packaging they require, and the standards they set for suppliers, they shape global industries — from seafood to consumer goods — and affect millions of workers, consumers, and communities around the world. With that influence comes responsibility.
These companies have the power to strengthen worker protections, reduce plastic pollution, eliminate hazardous chemicals, and raise environmental standards across their global supply chains. Their choices can improve the lives of workers, protect our oceans, and reshape entire industries. But they are not making them. Take, for example, Greenpeace US’s surveys that assess U.S. supermarkets’ policies on their seafood’s human rights and sustainability policies – all three consistently fail.
The solutions exist. It’s time these companies used their influence to protect people and the planet—not just their bottom line.



Why Now?
The decisions made by a handful of corporations have never carried more weight. As public protections are weakened and environmental and human rights challenges intensify, corporate leadership is more important than ever. Consumers increasingly expect companies to protect workers, reduce pollution, and build more responsible supply chains—and these companies have the power to deliver.
This is a pivotal moment for corporate accountability.
The evidence is growing.
Scientific research, investigations, and testimony from workers and frontline communities continue to expose the human and environmental costs of business as usual.
The solutions already exist.
From safer working conditions at sea to reuse systems that reduce plastic pollution, companies already have practical, scalable solutions within reach.
The moment to act is now.
The future isn’t decided by these companies alone. It’s shaped by what we demand of them. The choices these companies make today will shape the health of our communities, the future of our oceans, and the well-being of workers for years to come.
The future isn’t decided by these companies alone. It’s shaped by what we demand of them.
Join us in holding the Big 3 accountable.
