The civil construction industry is recognized as one of the activities with the greatest environmental impact on the planet, in addition to being responsible for about 10% to 20% of emissions in the extraction of raw materials and manufacture of products for this segment. The main objective of this work was to estimate greenhouse gas emissions for the construction of an administrative building at the Federal University of Rio de Janeiro, Brazil, using the modular constructive method. The methodology used to inventory emissions was structured in the Brazilian greenhouse gas protocol program, the method most used worldwide by companies and governments for conducting greenhouse gas inventories. The research was also developed by simulating its construction by the “Conventional” method using construction materials, a source of great relevance in the literature. Based on the results of the inventory, the total greenhouse gas emission was estimated at 462.90 tCO 2 e for the construction of the project, with a built area of 620.03 m 2 , which resulted in the emission of 0.75 tCO 2 e/m 2 of built area. Comparatively, this constructive method presented 22.12% less emissions when compared to the conventional method. This result allows, as a mitigation action, the possibility of proposing the implementation of new technologies and constructive methods that propitiate the reduction of greenhouse gas emissions.
