Steel production is highly reliant on coal, which is primarily used as a reducing agent to extract iron from iron ore and to provide the carbon content needed in steel. Over the past decade, total CO2 emissions from the iron and steel sector have risen, largely owning to increases in steel demand. The direct CO2 intensity of crude steel ...

We've helped move over a billion tonnes of iron ore, from pit to port. And we're focused on creating iron ore mines that produce zero CO 2 emissions, zero waste and higher ore grades. We deliver solutions across the iron ore value chain, starting at the concept phase of greenfield projects through to sustaining capital projects at older mines.
