  • 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

  • One order of steel; hold the greenhouse gases MIT News

    May 08, 2013· The prevailing process makes steel from iron ore — which is mostly iron oxide — by heating it with carbon; the process forms carbon dioxide as a byproduct. Production of a ton of steel generates almost two tons of CO2 emissions, according to steel industry figures, accounting for as much as 5 percent of the world’s total greenhouse-gas

  • Energy Efficiency and Industrial Output: The Case of the

    Dec 03, 2013· The iron and steel industry is one of the most carbon emitting and energy consuming sectors in Europe. At the same time this sector is of high economic importance for the European Union. Therefore, while public environmental and energy policies target this sector, there is political concern that it suffers too much from these policy measures.
