"Carbon is unlike any other commodity that's bought and sold at scale today" (Andrew Shebbeare)

For carbon removal to thrive under capitalism, we need thriving carbon removal businesses. And thriving carbon removal businesses need an income - but who's paying? Can a service like this, operating for the good of humanity, really work in a world that revolves around money?

That's the crux of this week's episode.

Carbon marketplaces offer one model: buy and sell carbon on the open market in the form of credits. It sounds straightforward enough, until you realise that no two tonnes of carbon removed from the atmosphere are the same. Plus, doesn't this kind of system just give greenwashing companies a licence to pollute?

Utilisation of carbon, rather than storage, is another potential revenue generator. Take your captured carbon, pop it in your product and sell on at a healthy margin. We focus on concrete here (for good reason), though the possibilities really are endless. Beyond the wow factor, does this bring the climate benefits we need?

Join us as we get to the business end of carbon removal and see carbon as we've never seen it before. Can money grow on trees or be produced out of thin air?
