Iron and Steel Analysis IEA
While the energy intensity of steel has gradually fallen since 2009, expanding production from 2009 to 2014 raised total energy demand and CO 2 emissions. After a small decline between 2014 and 2016, energy demand and CO 2 emissions increased in 2017 and 2018, primarily as a result of higher steel production.. Substantial cuts in total energy demand and CO 2 emissions will be needed by 2030 to
