      Not entirely. Some goes into the topsoil. Also if your guerilla project lives on one plant is replaced with another, so it is carbon negative compared with no plants in its place.

      You gotta sequester the carbon by harvesting the trees and then either building stuff (like buildings or furniture, not disposable goods) with them or burying/sinking them in anaerobic conditions so they can’t decompose.

          Biochar is cool and all, but it’s still not as good as preserving the wood completely intact. The article you cited itself says “it is predicted that at least 50% of the carbon in any piece of waste turned into biochar becomes stable,” which is quite a bit less than 100%.

          I suppose it’s good for the twigs and other leftovers that aren’t even good enough to be made into OSB or MDF panels.

      A little part stills goes to soil and other, we wouldn’t have coal if old trees decomposed all their CO2 back to the air

        Coal only exists because the bacteria did not exist yet to break the plant matter down when those trees died. New coal can not be formed now that the bacteria exist.

          It can be formed, just not in the vast quantities it was back then. It requires unusual conditions to stop fungi making a meal out of it, before it gets buried deep enough.
