Estratégias de descarbonização: estudo de caso no centro de tecnologia da Universidade Federal de Alagoas

Abstract

With the worsening of climate change, air pollution has gained prominence in global discussions, bringing the Greenhouse Effect into focus. When it comes to air pollution, the best approach is mitigation at the source, and this holds true for Greenhouse Gases (GHG) as well, which can be more easily quantified and managed through inventories. Considering the Technology Center as an important department at the Federal University of Alagoas for training new participants in the fight against global warming, the development of a Greenhouse Gas Inventory is essential. The chosen methodology was the 2024 Brazilian GHG Protocol Program, provided by the Getúlio Vargas Foundation, which involves identifying the study area, determining scope subcategories, collecting, and analyzing data. To obtain data, requests were made to SINFRA, the CTEC management, along with in-person counts and estimates. After creating the inventory, it was found that scopes 1 and 3 are the most significant in GHG emissions at the Technology Center under study. There is a large use of air conditioning units, which results in a high carbon dioxide equivalent emission, and another contributing factor is the generation of liquid effluents due to the significant number of people using the building, which consequently leads to high effluent output. Together, these factors contribute to a total emission of 675.22 tCO₂e. An action plan to improve GHG management was developed through a SWOT matrix, chosen for its ease of application and effectiveness, including actions such as a system for reusing generated effluents and electrifying the vehicle fleet.
