This work aimed to identify and quantify the greenhouse gas (GHG) emissions of a Brazilian steel industry. It identifies and quantifies the emissions for a further study of an effective action plan by the organization. As a result, it was found that Scope 1 emissions (direct emissions from the company) were the largest emissions from the industry, representing more than 89% of total emissions. The Stationary Combustion category presented the highest emission values mainly due to the use of natural gas and charcoal. Biogenic CO2 emissions have shown the importance of organizations adhering to biomass use as a raw material in their processes, thereby reducing their GHG emissions to the atmosphere. Scope 2 emissions (indirect emissions, comprising the energy category) represented 10.87% of total emissions, the configuration of the Brazilian energy matrix contributes to this scenario. In order to achieve a differential control that would provide an indicator for the organization, it was necessary to adapt the tool for a monthly report. The studied company was interested in carrying out a more detailed monitoring, in a shorter time reporting of its emissions. Thus, after the results referring to the quantification of GHG emissions for the annual report, the results referring to the adaptation carried out in the GHG Protocol tool, version 2018.1.4 were also presented in this work.

“…Segundo Carvalho (2017), para solucionar a elevação da temperatura do planeta é importante conhecer e quantificar os gases de efeito estufa e suas respectivas fontes. Para isso, as organizações estão executando inventários dessas emissões, objetivando identificá-las e estabelecer mecanismos de mitigação.…”

Greenhouse Gas emissions inventories are strategic environmental management tools that estimate emissions by specific sources in a given geographical area and timeframe. Developing an inventory is the first step in creating programs to improve air quality. This research aimed to prepare a GHG inventory and propose a management of its emissions from the activities of the Sanitation Company of Alagoas (Casal) in the Capital Unit in 2018. The methodology employed involved literature analysis to identify the most appropriate method for inventory preparation, data collection in various units of the company, interviews with managers and GHG accounting. The methodology used for the estimation was that indicated by the Brazilian GHG Protocol Program, complemented by the guidelines of the Intergovernmental Panel on Climate Change (IPCC) for the case of sewage treatment. The results of the GHG emissions inventory indicate that in 2018, Casal, Capital unit emitted 31,099.33 tCO2e, of which 86.7% (26,980.70 tCO2e) came from direct emissions, while indirect ones represented 13. 3% (4,118.63 tCO2e). The company's main sources of emissions were the sewage treatment and energy consumption categories, respectively. The results form the basis for the incorporation of GHG reduction measures in the company's strategic planning.
