Trade networks connect distant places, often in ways we don’t expect. This study looks at how producing goods in the U.S. affects ecosystems far from where the goods are used. We track how much plant material (like crops, grass, or trees) people remove from the land through farming, logging, and grazing. Then, we infer the carbon content of that plant material, and model how that carbon gets tied up in refined goods like furniture or construction materials. This allows us to measure how much hidden environmental impact is built into goods as they move through the supply chain. The goal is to show how trade can shift environmental pressure from one place to another and to encourage policies that consider these system-wide effects, especially when making decisions about how we use land.
