  Just a reminder that concrete releases huge amounts of CO2 as it cures. Empty cities don’t help anyone.

    Another reason good urbanism and walkability is super important: the emissions don’t just come from the cars, they come from the excess roads themselves, too.

    i don’t think their intention is to keep them empty. not the worst thing to spend co2 on.

      Their intention was to bolster the economy with busy work, but that’s not a long term solution.

        busywork making houses ahead of time is pretty good tbh.

      It wasn’t even necessarily a bad idea given property growth, but it will be interesting to see what happens if they can’t stop population decline

    cement releases large amounts of CO2 when it is being produced, i.e. when the cement powder is being produced from limestone.

    later, when you mix the cement with water and sand to make concrete, it re-absorbs that CO2. you’ve got it backwards :D
