bricks made by burning clay aren’t that much better. Especially considering that you need more bricks for columns and other load bearing structures.
Comment on anons brother has some strong opinions

Concrete is a major driver of CO2 emissions. Fuck concrete.

And the alternative would be building with wood which I believe would be even worse

Depends on what you want to do. Wood buildings have more limits in terms of height and structural load. But wood usually means much lower emissions and easier recycling of the building. Of course fire safety is another issue. In comparision to steel, wood does surprisingly well, as a thick wooden column can be burning on the outside, but maintain its load bearing capability on the inside. steel transmits the heat to its inside quickly and looses its stability faster.

It’s a major driver because of how much it is used. It’s the building material, nothing else even really comes close. If we used bricks to the same degree, that would be the major driver.
There’s often no good alternative to concrete. There’s lots of newer less CO2 intensive cements and cement replacements out there though. Often comes at a cost on something else though.

Bricks would be much more efficient co2 wise, they don’t have the curing process that pollutes

They also put out a lot of CO2 and you’d have a hell of a lot of issues scaling the brick production to the same level. Not to mention all the othe associated issues that bricks have.
It’s just a poor replacement for concrete at the same scale. But that’s not to knock bricks specifically, since nothing really is a good replacement at that scale.
Best we could do is to not build as much or in such a big scale, but that has issues too.

You can bake bricks using clean energy but the chemical process for creating cement itself creates co2… Y’all down voting and never held a brick in yer lives

Don’t you have to fire bricks in a kiln? Surely that puts off some CO2?

You just cook them up electrically, I haven’t seen a charcoal kiln in ages

I wonder how the co2 from drying/making bricks compares
