Most of its steel and other metals, so assuming that theyre using electrically pwered smelters most of the emmissions would be in transport and mining equiptment. So probably somewhat comparable, depends on how much rail was used or if it was transportes exclusively via semi.
Most steel is (unfortunately) made in Chinese blast furnaces using coal coke and powered with electricity from coal power plants.
Im aware, I was giving a best possible circumstances type situation. Still the steel for both is probably sourced from the same factory.
And all steel is made using coal regardless of where it's produced, except in experimental processes like HYBRIT.

Some producers use electric arc furnaces, a few of which use only scrap metal as input, which means they need far less coal and emit far less CO2 than a conventional BOF/BFF setup.
