At any given moment, crude oil is being pumped up from the depths of the planet. Some of that sludge gets sent to a refinery and processed into plastic, then it becomes the phone in your hand, the shades on your window, the ornaments hanging from your Christmas tree.

Although scientists know how much carbon dioxide is emitted to make these products (a new iPhone is akin to driving more than 200 miles), there’s little research into how much gets stashed away in them. A study published on Friday in the journal Cell Reports Sustainability estimates that billions of tons of carbon from fossil fuels — coal, oil, and gas — was stored in gadgets, building materials, and other long-lasting human-made items over a recent 25 year period, tucked away in what the researchers call the “technosphere.”

According to the study by researchers at the University of Groningen in the Netherlands, 400 million tons of carbon gets added to the technosphere’s stockpile every year, growing at a slightly faster rate than fossil fuel emissions. But in many cases, the technosphere doesn’t keep that carbon permanently; if objects get thrown away and incinerated, they wind up warming the atmosphere, too. In 2011, 9 percent of all extracted fossil carbon was sunk into items and infrastructure in the technosphere, an amount that would almost equal that year’s emissions from the European Union if it were burned.
