How can we fight climate change by focusing underground?

It turns out one of the biggest untapped climate solutions isn’t in the air—or in the trees, it’s in the soil beneath our feet. Today’s guest has developed a game-changing way to measure and protect soil organic carbon, helping farmers, agribusinesses, and carbon markets work together for climate impact and economic resilience.

Our guest is Chris Tolles, Founder & CEO of Yard Stick PBC.

Some quotes to hook you:

“Soils store way, way more carbon than all the trees and plants and animals combined.”

“If you want to sell soil carbon credits, you’ve got to measure soil carbon—accurately and at scale.”

“Healthy soils aren’t just about climate—they’re about keeping Cheerios on the shelves.”

“Identify the application of your technology that helps someone make money or save money—that’s what all businesses do.”
