摘要：Concern about greenhouse gases has been a widespread theme among scientific communities in relation to the impacts on the environment over the years. Public policies increasingly tighten their actions to mitigate the damages that man causes to the planet, developing mechanisms of control and monitoring. Companies, in turn, begin to realize the issue, not only for improving the quality of life and sustainability of biological structures, but also as a way to secure their business strategically. From the study carried out at a steel smelter in the city of Sorocaba, the emission sources were mapped and the related data were analyzed according to the parameters established by the Greenhouse Gases Protocol. The emissions of the years 2013 and 2014 were observed, establishing a comparative analysis and pointing out the main actions of greater relevance in the process of reduction of these sources.
