Trees are a good way to remove CO2 from the atmosphere but when it is burned or rots the carbon is re-released into the environment.
Eventually there is little net gain.
Manufacturing steel and concrete for construction creates tremendous quantities of CO2.
Wood is far more durable than steel and concrete. It is not likely to fail as a result of repeated flexing. Steel gets brittle and fails. Concrete is very brittle and cracks readily.
Well preserved wood could be used to build tall buildings and bridges with longer life. The CO2 would be locked up and the atmosphere would be helped.
Trees absorb the most CO2 early in their life cycles. Once mature they should be harvested, utilized, and new trees planted.
Wood can be made to not rot, and not be affected by water, oil or salt. It is not structurally weakened by heat until it actually burns.
If fire occurs, once extinguished, a building can quickly be returned to useful service. Good construction material. It even LOOKS good.
