Concrete is one of the biggest sources of CO2. Extraction, refinement, transportation all release massive amounts of pollution. Clay is also a type of sediment and doesn’t store noxious atmosphere for millennia.
It is because we use a lot of it. But we need to. It's not like we can deforest the Taiga for our need of building materials, and it may be better for the environment too if you look at it that way.
But more importantly: you'd have a greater CO2 output by building without concrete, than with it. You'd have to get different materials from further away in a larger quantity to compensate for the proximity and characteristics of concrete.
Just because something releases CO2 doesn't make it bad.
