Trey Hill led a small group of fellow farmers to a field outside his office in Rock Hall on Maryland’s Eastern Shore. It was a cloudy February day, but the ground was alive with color — purple and red turnip tops mixing exuberantly with green rye, vetch and clover, and beneath it all, rich brown soil. Hill reached down, yanked a long, thick, white daikon radish from the earth and showed his visitors sumptuous coffee-colored clods clinging to hairy rootlets. Those clumps, he explained, hoard carbon — carbon that’s not heating the planet.
Hill didn’t adopt “carbon smart” practices like cover-cropping to fight climate change. He did it to build soil, retain water, and make money. But when the third-generation corn, wheat, and soybean farmer learned about Nori, a Seattle-based startup looking to sell credits for carbon stored in the soils of farms like his, he was all in. Hill didn’t necessarily expect a windfall, but he wanted to show fellow farmers they could make money while helping fight climate change. “If it works out and we make some money on it, that’s great,” Hill says. “If it doesn’t, well, somebody’s got to be first, and we’re willing to take that risk.”
Earlier this year, Nori paid Hill $115,000 for just over 8,000 tons of carbon stored in Hill’s soil. In the future, if each of the 10,000 acres he farms can sock away an additional ton of carbon per year — around the best he could hope for, he says — he could earn up to $150,000 annually.
As efforts to wean society off fossil fuels have stalled, “natural climate solutions” such as soil carbon sequestration have rapidly gained steam. In 2018, the National Academies of Sciences, Engineering, and Medicine reported that “negative emissions technologies” — techniques for removing carbon from the atmosphere, rather than simply reducing new emissions of carbon — are needed to stabilize global warming below 2 degrees Celsius (3.6 degrees Fahrenheit), the level scientists believe could be catastrophic.
