RESUMO:

Within the context of tackling climate change and global warming, including the achievement of goals to which Brazil committed itself when adhering to the Paris Agreement through Nationally Determined Contributions (NDC), attention is drawn to the leadership role of High Education Institutions (HEIs) in the global scenario, so that they account for the greenhouse gas emissions (GHG) resulting from their activities through the preparation of inventories. This research aims to propose a GHG inventory model adapted to the reality of the HEIs in order to facilitate the elaboration, understanding, dissemination and updating among institutions and the general public, as well as proposing strategies to mitigate emissions caused in the exercise of their institutional activities. To this end, a case study was carried out at UFS with the elaboration of a GHG inventory, for the base year 2017, using the GHG Protocol methodology widely recognized by the scientific community, based on the identification of its main sources (CO2, N2O, CH4, HFCs, SF6 and PFCs), segmented by categories and scopes (1, 2 and 3) and their results compared with those of scientific works at national and international level between HEIs, in order to extract similar points and possible divergences. The results demonstrate that, among UFS GHG emissions for the year inventoried, the highest emissions correspond to scope 3, with 24,293 tCO2e. Next, scope 2 emissions, with 1,633 tCO2e, and lastly, scope 1 emissions, with 755.42 tCO2e. Some mitigation measures have been suggested to reduce GHG, with a special emphasis on expanding the photovoltaic system to allow the generation of sufficient electricity to meet the demand of all the campuses of the institution, with the exception of the São Cristóvão Campus, and whose technical and economic viability was also elaborated. The comparative analysis with studies in other HEIs highlighted that the accounting for scope 3 emissions is particularly important because it identifies the performance of activities related to the various categories covered in it, in particular, business trips, displacement of employees and students (home-work), goods and services purchased, waste disposal and that some categories foreseen in the Brazilian GHG Protocol Program (PBGHGP) may be overlooked, given the inapplicability to IES. Based on these findings, a customized model for HEI inventories was formulated in a practical and didactic way, that explains step by step how to account for GHG emissions. Thus, conclusions indicated that the accounting of emissions through inventories can contribute to the fulfillment of the national goal of GHG reduction by assisting in the planning of goals and objectives and enabling the adoption of mitigating measures by the HEIs. However, it is recommended that this study be improved, notably with regard to the analysis of the technical, environmental and economic feasibility of the GHG reduction measures suggested in comparison with the reality presented by each HEI aiming at creating a standardization also under such aspect.
