Decarbonising global iron ore and steel industry by 2050
From iron ore mining to steel manufacturing, the industry is highly carbon intensive. Iron and steel production emit a combined 3.4 billion tonnes of carbon annually - equal to 7% of global emissions. Malan Wu, research director at Wood Mackenzie, and lead author of the report, said: "Decarbonising the steel industry is a staggeringly big task.

Iron ore
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.

Steel industry emissions are a big contributor to climate
Braun estimates that emissions from Electra's process currently only equal one-third of the weight of the iron—and nearly all come from mining and processing iron ore before it reaches their plant. At a pilot plant, Boston Metal, which previously received money from ARPA-E, also relies on electricity to separate and purify iron.
