Plus, it's my impression (it could be very effective marketing by the lumber industry) that lumber trees are quickly grown and chopped in farms and controlled logging. And the next tree is planted. I'd guess that construction is probably a pretty good sequester for the wood/carbon in terms of length of service, and likelihood for controlled recycling or burial after its done. The logging industry is likely incented to maximize the carbon sequestration rate: which is growing trees producing future lumber.
