Many of the innovators we’ve spoken with this season are launching technologies or business models that produce less carbon than status quo approaches – leather made from mushrooms instead of cows, for example, and vehicles that run on electricity instead of fossil fuels. Other guests are finding new ways to finance those new technologies or business models. In this episode, we meet Steve Oldham, the CEO of Carbon Engineering, who is tackling climate change from a different angle – by developing a technology that captures carbon already in the air. The potential benefits of this approach are huge, but the challenges are at this point significant.
