concrete puts out around 180kg per ton. a pine tree planted for harvesting lives about 20 years, will absorb 100-300kg in that lifetime, will supply more material in both weight and volume, and when processed into CLT that material will be much stronger per unit weight. let's be generous to concrete and say we're only absorbing 100kg per 20 years, only get one ton of material, and that CLT is only twice as strong as concrete (it can be ~5x or higher in some cases). this still means one tree will have a 640kg advantage over concrete for the same output. if we're even more generous to concrete and assume _only_ timber has wildly inefficient production and construction methods, the advantage is still in the order of hundreds of kgs.
