It releases quite a lot of carbon dioxide per tonne cement clinker yes.Concrete is pretty grim environmentally

But the tonnages consumed in a developed economy are rather small.
It is also a stream well suited to capture and reuse or storage, compared to power plant consumption.
Note how small the EU segment of that emissions curve is - even though the EU has a population of 500 million near first world people.
You only expend cement once essentailly.
