When we talk about carbon removal, we often focus on “direct air capture” facilities — big factories that suck carbon dioxide out of the ambient air.   But a simpler and easier way to remove carbon from the atmosphere may exist. It’s called “enhanced rock weathering” — grinding up rocks, spreading them out, and exposing them to the ambient air — and it works, essentially, by speeding up the Earth’s carbon cycle. Enhanced rock weathering recently got a major vote of confidence from Frontier, a consortium of tech and finance companies who have teamed up to support new and experimental carbon removal technologies. In this episode, we speak with Jane Flegal, a former Biden White House climate adviser and now the market development and policy lead at Frontier, about the promise of enhanced rock weathering and why Frontier just spent $57 million to do it. Mentioned:  Why Big Tech is pouring $925 million into carbon removal. More about Frontier’s commitment to Lithos. Enhanced weathering in the US Corn Belt delivers carbon removal with agronomic benefits. Rob’s downshift, Rob’s upshift.
