If we used cross-laminated timber [1] to construct our buildings instead of concrete, there would be an economical incentive to keep a lot of timber forests around. For additional carbon-negativity (and soil quality!) the timber industry could be required to biochar and bury its litter. This way, without too much government coercion, maybe our building frenzy [2] could end up being carbon negative? Much like modern diesel engines that make (polluted) air clean(er) [3].
