Did you read that link before posting?
In comparison with other construction materials (aluminium, steel, even brick), concrete is one of the least energy-intensive building materials.[2]

Except it isn't just about the energy intensity, but specifically the CO2 emission from the concrete process itself.
From the link's sources:
-
The issue isn't concrete or cement inherently but how much of is used. And it's used because it's either the most cost-effective material or just the only one able to deliver the required specs.
-
I thought the issue was sand/silica and the fact that we may exhaust the ressources to do cement eventually. It takes a lot of sand materials if I recall correctly ?
-
And not just any sand.

it's so bad that people are literally stealing sand from beaches to sell under the table
