Hydraulic cement does not produce CO2 during setting. Non-hydraulic cement actually consumes CO2 while setting.

  Doesn't it essentially just re-absorb the same co2 it emitted when it was made?

    Yes. I was replying to parent's comment that concrete produces CO2 when setting, which is clearly not the case for hydraulic cement.
