The steel industry is one of the largest emitters of CO2, contributing 6%–7% of global greenhouse gas emissions. That said, there's a difference between sourcing that carbon from fossil fuels, carbon "new" to the current land|sea|atmosphere cycle having been drawn up from where it was sequestered millions of years past, and carbon that is already part of the surface dynamic. Major steel players, those in the billion tonne per annum mining and processing chain, are already going hard at replacing current steel making with several alternatives and have already built pilot plants to trial low | zero "new carbon" production techniques. eg: Rio's BioIron: https://www.riotinto.com/en/news/stories/decarbonising-steel... is one such trial, IIRC that link mentions others. |
