Reply to comment by ApparentlyABot in Scientists have figured out a way to engineer wood to trap carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction by giuliomagnifico

Creating concrete takes a lot of energy, which is one source of CO2, but creating cement releases CO2 in one step of the process. Even if you had a 100% carbon-free source of energy, creating cement still produces CO2.

Yes, except that it's a low energy process (compared to steel, or even making CLT).

The volumes are gigantic, however.
