I am in opposition to OPC too, I am just not sure what else has the same properties?
Though they are trickier to work with, pazzolans and lime stabilization. Adobe (clay) is also a stabilizer.
I am hoping for industrial hemp to be grown in the US again (and it is already starting up in Colorado). Hemp hurds mixed into a hydraulic lime slurry makes "hempcrete", which is much better than OPC from a CO2 perspective. Hempcrete requires no rebar, is flexible (much better seismic tolerance), and has a higher R-value. Poured hempcrete floors are actually comfortable to walk on. It's easy to make walls, too, with a slip-form.
