The CO2 comes from adding the coke to make steel, not getting the thing hot

Depends on how it’s powered. If the electricity comes from burning coal (coke) or methane, that would emit co2. If it runs off solar/hydro/wind it would only emit co2 from any carbon trapped in the iron ore that manages to burn instead of becoming incorporated into the steel.
