Low-carbon production of iron and steel: Technology ...

Given increased urgency to transition the global economy to net-zero CO 2 emission, governments and industry have increased focus on decarbonizing hard-to-abate sectors, including steel making, which contributes roughly 6% of global CO 2 emission and 8% of energy-related emission (including power consumption emission). This paper reviews current global iron and

Climate change and the production of iron and steel ...

Transforming steel production. Iron is made by removing oxygen and other impurities from iron ore. When iron is combined with carbon, recycled steel and small amounts of other elements it becomes steel. Once made, it is a permanent resource; it is 100% and infinitely recyclable without any loss of properties.
