    Green steel made from Baffinland iron

    Shane Lasley, Data Mine North|Updated Mar 9, 2024

    European steelmakers are looking across the Atlantic for high-quality iron ore mined on Canada's Baffin Island. Due to the combination of high strength, low cost, and the abundance of the minerals and metals from which it is made, steel is the most used metal on Earth. The making of this alloy that serves as the skeleton of modern society, however, is also responsible for roughly 8% of global carbon dioxide emissions. To help reduce the CO2 footprint of this building material... Full story
