    About new concrete mixes under development that would actually be carbon-negative and capture carbon as it's made or cured.  If it can be done, it would be a big change from the current situation, where concrete is among the larger generators of carbon dioxide (depending on what source you consult, we get from 5 to 7% of the world's carbon emissions from it).

    •  That would be awesome (0+ / 0-)

      I think that things like that could definitely have their place. I'm just nervous about people sitting back and thinking that we'll find the technology to fix this by taking carbon out of the air. I think that we still need to focus on keeping the carbon out of the air in the first place. But I do agree that technologies like what you speak of do show promise.
