Why aren't our "leaders" supporting sustainable cement?

    According to the article below, the type of cement we use in concrete creates a LOT of CO2. And there are other types of cement that are stronger and create a lot LESS CO2.

    This one change wouldn't halt climate change, but it would help. So why aren't our so-called "leaders" making this happen? It seems like a really easy thing to subsidize the alternatives, or tariff the existing cement..

    Simply, there's no three word slogan that includes the word "cement." Four words would be a turn-off, it suggests complexity.

    "Lock Cement Up" and "Get Cement Done" just aren't inspiring enough for the public to get behind.

    Good question

    I recall reading years ago about Japan starting to use ash from high temperature garbage incinerators to mix into cement, kinda wondered why I never really heard anything more about it ( Maybe I didn't look )

    It's a complicated problem, with the alternative cements requiring
    different processing, & therefore different facility design. And then
    there are different properties to deal with. Will they hold up in all
    the customer applications?
    Some are already in use where performance has superior
    characteristics, eg, low exothermic reactions for use in massive
    structures like dams (which even require cooling systems).
    The market won't switch over fully or soon.

    This is the kind of call that a well-funded Department of Environment could make. All it takes is a leader that would give (or return?) the mandate and resources to the organisation.

    Hint, hint.....

    Whenever we can't get our leaders to move on an issue that we all want and need it's safe to assume it's because they are being "encouraged" to stay put.

    Or they simply don't care all that much.
    So many who say they care don't exhibit this in their own lifestyle.
    This tells me that their pro-environment proclamations are pandering.
    If the voters started clamoring for sustainable cement, leaders might
    sense that action leads to election.

    Most leaders are lawyers, not numbers people. They may have survived Math courses, but they aren't into that. They also have a lot of other interests. You're talking about meetings, phone calls, canceling other meetings... They need clear answers to their technical questions by people they trust whom they know are not merely backing some new product or industry. They need simple answers. What clear answers exist? What simple answers exist? They also need to know how these solutions affect their patrons and their electorate.

    And so we will see a BILLION people displaced from their homes due to rising sea levels, but of course we couldn't ask our leaders to be inconvenienced to think.

    Could do that as well, not sure how well it works for huge constructions. But wood is a good material.

    The skyscraper of the future is made of wood

    VARIOUS PARTS OF the world are erecting taller wooden buildings than could ever have been imagined a few decades ago. The tallest so far is the recently built Treet, a 45 metre, 14-storey block in Bergen. There are even plans to build wooden structures that fall into the category of skyscrapers, i.e. buildings over 100 metres high. In Canada a detailed investigation, based on research, has shown that it is both technically and economically viable to build 30-storey buildings around a wooden structural frame and that this brings major environmental benefits. The American architectural firm Skidmore, Owings & Merrill has conducted a similar study of a 42-storey building.

    In Sweden, as in the rest of Europe, stone, brick and concrete have long been the dominant construction materials for apartment blocks. A rapidly growing population in the large cities and a threatening climate crisis are forcing us to think along new lines. Greater use of wood as a construction material for buildings is part of the solution. Supply is good, the material is green and it is easy to work with in a factory or on a building site. The fact that living in wooden homes is also pleasant and comfortable has been confirmed by Technische Universit├Ąt Graz in Austria.

    Sustainable construction: wooden house

    Well its not like we can't use concrete at all, so for certain tasks you could use it.

    ;) I'm saying that we can expect them to think, but they aren't engineers, mostly; and they are surrounded by influences constantly people yammering. That is why this is something which can only be brought to their attention when there is definite action they can take...like a lever they can pull or a panic button.

    Also our electorate is not yet wise to the problem of pollsters. We answer surveys. We announce our opinions online, and we shouldn't. What every voter should do is send between 50 cents to five dollars to EVERY political camp, and confuse the hell out of the pollsters as much as possible. This will (given time) weaken the lobbies and strengthen the voice of individual voters. Long ago voters should have been advised to refuse telephone surveys and all kinds of surveys. What we have done, instead, is freely place ourselves into neat columns into pollsters spreadsheets. We need to climb out of those spreadsheets. Gallup knows where we live, what we believe and whom we vote for; and this allows them to focus their attentions in distracting those whom we, the voters, need to listen to us. You might say that the problem isn't just that the leaders aren't thinking but that the electorate is undermined by information technology which is getting increasingly invasive. Your vote and mine goes for pennies on the dollar.

    My sense is that - in addition to what you said - most of them have been corrupted. I suspect many are good people, but they've been forcibly coerced :(
