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

      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

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

          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

              You can also cpature the CO2 and use it in chemical processes where it is needed. Bizarrely often they’re buying the CO2 for high price even though if capture methods were common we’d have loads of stock. And lower CO2 emission cement is already a thing that’s happening, but being able to scale brick production to meet even close to the scale of concret construction is nowhere near reality.

              I like bricks as a facade element but it’s just not a good replacement for concrete on the whole. It will be much much easier to try and mitigate the issues concret has than to get bricks to the level of concrete construction globally.

              Also I work in construction with both concrete and bricks and have been involved in mass production of both. But go off lol

      bricks made by burning clay aren’t that much better. Especially considering that you need more bricks for columns and other load bearing structures.
