There are now 800 carbon removal startups. How many is too many?

Tackling climate change now requires not just reducing planet-warming emissions to zero, but also finding a way to draw down existing carbon dioxide from the air. Over the past few years, tech companies have taken the lead to seed hundreds of startups that want to sell carbon removal credits and help companies meet climate goals. But the failure of a major startup, Running Tide, has raised questions about the long-term viability of the market. This week on Zero, we hear from Nan Ransohoff, head of climate at Stripe, and pioneer of the carbon-removal market.
