The increase in demands related to various sectors of society, mainly with the use of land and energy, intensified the generation and disposal of solid waste and greenhouse gas (GHG) emissions. As a result, measures aimed at controlling and minimizing GHG emissions had to become a reality and one of these measures was the creation of an indicator called the carbon footprint or CF indicator, which counts carbon emissions from various activities or across the life cicle stages of a product. One of the main sources of GHG generation is the generation of urban solid waste, which involves the collection, transport and final disposal in a sanitary landfill, with all stages capable of generating GHG; and the consumption of electricity. Therefore, the objective of this study was the quantification of GHG from the electric energy consumption and the generation of urban solid waste at the School of Engineering of Lorena. For this, the methodology described in the Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Inventories Volume 5 on Waste and the average monthly emission factor of the Brazilian Interconnected System (SIN) for the base years 2021 and 2022 were used. As a result, it was obtained that the potential that the total emission from electricity consumption during the years 2021 and 2022 was 1,194.0 and 347.3 tons of carbon dioxide (tCO2), respectively. The potential for generating methane (CH4) from the generation of waste at the School of Engineering of Lorena was 2,11 tCH4. These values are below the GHG generation of other universities consulted, however, it is worth mentioning that the period analyzed in this study comprises the period of suspension of academic classroom activities. It is recommended that these analyzes be carried out semi-annually to assess the impact of the return of face-to-face activities on campus.
