China has commissioned its first steel line built for near-zero-carbon production at million-tonne scale — a marker of how quickly green steelmaking is moving from pilot projects to industrial reality. For the wider market, the milestone raises the bar on decarbonisation for every major producing country, India included. It also hints at how demand may shift in the inputs that low-emission routes rely on, from higher-grade ore and pellets to cleaner reductants, as more capacity of this kind is sanctioned and the premium for green steel starts to be tested commercially.
