Sorry for being pedantic, but isn't carbon-free steel just iron?

  Pretty sure he meant carbon emissions, but technically you are correct, "steel" is a mixture of iron and a relatively small amount of carbon. As far as I know (but I am not an expert) there are not many applications for elemental (pure) iron.

  The carbon in the steel is a tiny fraction of the carbon used to make coke which fuels the process. This is similar to plastics. Sure, plastics use petroleum. However, if we quit burning petroleum for cars, suddenly we have 100+ years of petroleum reserves for plastics.

    Oh wow, serious brain-fart on this side. Now that you say it I realize i was kind of being dense - thanks for spelling it out!
