Abstract:
Climate change is one of humanity's greatest challenges [1]. The effects of climate change on planet Earth are increasingly present in everyday life, causing environmental imbalances, thus strongly impacting the terrestrial ecosystem. According to the IPPC (The Intergovernmental Panel on Climate Change is the United Nations) [2] the increase in greenhouse effect emissions (GHG) is being caused by human activity, is causing climate change. Greenhouse gas emissions cover the Earth, trapping the sun's heat, generating global warming and climate change. Faced with this climate challenge, on December 12, 2015 in Paris, an international treaty was established to combat climate change, signed by 196 countries that committed to complying with the treaty as of November 4, 2016. The Paris agreement's main objective is to limit global warming below 2, preferably 1.5 degrees Celsius [3] . This climate action plan (Net Zero 2050) provides for the goal of zeroing net emissions of greenhouse gases by the year 2050), according to the International Energy Agency (IEA) [4] Steel is an essential material for the technological development of society. According to the International Energy Agency (IEA) [5] the steel sector, among the heavy industries, ranks first in CO2 emissions and second in terms of energy consumption. Iron and steel account directly for 2.6 gigatons of carbon dioxide (GT CO2) emissions annually, with 7% of the global energy system total. Based on this analysis of these studies, this work aims to analyze the processes of decarbonization of the steel sector for the production of sustainable steel and its contribution to the reduction of carbon dioxide in the atmosphere, meeting the goals of the Paris Agreement
