Holding back carbon from combustion will increase the feedstock demand. This
is a non issue if the feedstock is free, or, even better, a waste stream with a
disposal cost that can now be avoided. Of course an increase in garden
productivity, or a sufficient market value for the charcoal, could eliminate
any extra cost even if the feedstock has to be purchased. And all this with no
credit for sequestering carbon.
In sum, the entire value chain has to be taken into account, not simply a few
cherry picked data points such as the increase in feedstock required.
