It’s not inherently bad. It’s just funny when they are being hypocritical by pouring large amounts for useless structures like windmills. The amount of energy required to produce cement emits a lot of CO2. Concrete producers use pozzolans (fly ash, slag, silica fume) to reduce the carbon footprint of cement production and to make better, more durable concrete. They have even begun injecting CO2 into concrete during the mixing process to help trap the gas and form small limestone particles.
All they do is mix up a few ingredients....like making cake batter....I still don't understand how concrete can be bad....maybe if you didn't wash it off your hands while you were pouring it......but really.....
To be fair, it's the concrete powder that takes enormous amounts of energy to produce. I'm no expert but I believe it's a certain type of sand which has to be heated and dried at very high temperatures.
Mixing it with water only takes a fraction of that energy. :)
Environmentalists are carefully touching the topic, knowing that if people know that concrete isn't very environmentally friendly, they might choose to live in wooden single family homes instead of commie blocks. Some of them even goes so far that they wanna build commie blocks and even parking garages in wood instead of concrete. Now that's insane.
Why is concrete bad?

Takes massive amounts of energy to produce and can't really be recycled. So we'd better use it effectively.

Sea walls for rising oceans, duh /s
