    The greater point I’m getting at is whatever aggregate you use to make more concrete, making the concrete with Portland is still 8 percent of CO2 emissions. You can protect local environments and maintain concrete production, but what use is that when you’re cooking the planet with the concrete in the first place? Gotta stop liberating the CO2 from rocks, not green wash it.
