Concrete has horrible greenhouse gas emissions issues that wooden construction doesn't. The chemical reaction for the cement in concrete generates C02 in a 1:1 ratio with the amount of cement produced. Unless you're capturing it you release 1 ton of C02 for your 1 ton of cement. Steel for rebar is even worse, the ratio of C02 generated is greater than 1:1. None of this includes any of the energy you used to heat any of the ingredients either. Even plastic is better, some of the Carbon & oxygen get sequestered in the plastic. A process to completely sequester or not generate any C02 in the production of cement & concrete that was cheap & easy would be a Nobel prize winning innovation. If the whole world switched to that it would be more significant than switching all vehicles in the world to electric.
