Presumably China adopted some of the pollution control technologies developed in the 1970s as it industrialized.
edit: It's pretty likely that steel production since 2010 is greater than all steel production prior to 1900. I would think that the energy used to make steel since 2010 is at least comparable to the energy used for all metal production prior to 1900.
Industrialization certainly got started prior to 1900. I would say it took a while to really hit it's stride.
