It's supposed to suck carbon out of the air, reduce air pollution and even generate energy. Biochar is produced by burning stubble, wood and other biomass and could help us solve many problems. But does it live up to the hype?

We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.
