How Much Green Stuff Is There?

Even using sustainable feed stock, the savings in our global greenhouse gas omissions could be seven to 12 % of our current emissions. But i've seen estimates that go up to 16% if we increase the yield by adding things like potassium and calcium to the biochar. How much land might we need for this? Well, it's a good question. We need to make sure that we're only using a kind of abandoned, degraded er land that isn't used for food or is going to be compromising by adiversity. The i pc c estimate there could be an area the size of brazil available. That'sa uni currently abandoned crop land, for example.
