Most countries don’t and won’t do that, though. Coal is only expensive when a society agrees to stop externalizing the costs, and that only works if either most major countries are doing it or when they severely restrict trade with countries that keep externalizing the costs.
Use hydrogen for that (using coal creates 1.5 tons CO² per ton steel). Green steel needs no phosphor and sulfur too, making it stronger.
Hydrogen isn’t cheap, though.
Gets cheaper though.
It is if you have a nuclear power plant
Ah yes, the famously cheap nuclear power plant.
How expensive is it per MWh compared with coal if you account for removing the CO2 from the atmosphere?

and that is unfortunately game theory problem without working solution, which is why we are fucked :(
