What is green steel? The metal that’s trying to quit coal without losing its mind

Green steel sounds like a marketing intern got loose with a color wheel. It’s not. It’s steel made with far lower greenhouse-gas emissions than the usual coal-heavy route—and that matters because steelmaking is responsible for roughly 7%–8% of global human-caused greenhouse-gas emissions. In other words: this is not some niche industrial hobby. This is one of the big beasts.
