How environmentally friendly is concrete? I've heard cement is responsible for 5% to 8% of CO2 emissions globally.

Fun fact: Txdot, who spends 97% of their entire massive budget on expanding freeways, is responsible for .5% of all global carbon emissions.

That’s astounding. Are there similar figures available for other recent huge builders (e.g. China, both road infrastructure and dams etc)

Yeah, this was my question as well. Obviously wood has its downsides as a building material, but it seems to have some obvious advantages when it comes to renewability and sustainability.

Mostly public works projects, iirc. Housing is not a big contributor.
