I'm not sure what you are referring to but the carbon in the wood of a house is effectively sequestered. I've heard the equivalent amount of hemp made into boards holds 60% more carbon than tree wood so perhaps that would be better, depending on the carbon required to convert the hemp to usable lumber.
