Is steel considered bad now? I would think the larger concerns from buildings would be all the plastic and fiberglass type components rather than the steel or concrete structures themselves.
as the article kind of notes steelmaking in specific is very carbon intensive, so we either need to use less of it or decarbonize its production (or more likely a mixture of both). the statistics on this according to Wikipedia are:
Makes sense, given that steel is an iron/carbon alloy. I guess decarbonization would be making the process more efficient and capturing more of the carbon into the steel?
my understanding is yes that's the general avenue people are researching; there's also the actual energy inputs powering steelmaking that hypothetically can be made greener (currently, it's a process that seems to almost exclusively use fossil fuels because of the very high temperatures needed)
