Steel plays a very important role in our everyday lives, from infrastructure to buildings, automobiles, home appliances, and even kitchen cutlery. Without steel, our modern way of living would not be possible.

Unfortunately, the carbon dioxide (CO2) emissions related to steel are just as big of an issue as its role and are one of the leading sources of global warming. Over 10% of all global CO2 emissions or more than 2,500,000,000 tons of CO2 per year are coming from iron and steel making. This is three times as much as the CO2 emissions from all flights and aviation combined.
