CARBON FOOTPRINT OF THE FOUNDATION WORK FOR A PUBLIC BUILDING IN RIO GRANDE DO SUL, BRAZIL

Resumo

The construction sector plays a significant role in advancing economic and social development, but it is also responsible for a high consumption of natural resources and the emission of large quantities of carbon dioxide. The aim of this research was therefore to determine the carbon dioxide emissions of a foundation project and to analyze how they could be neutralized by planting trees. The methodology involved a qualitative and quantitative survey of a foundation project in the state of Rio Grande do Sul / Brazil, with two combinations of emission factors, one national and the other international. The results were evaluated and discussed, and the emissions found were analyzed in relation to neutralization. The study revealed that the international combination had the highest emissions, amounting to 22.286 tCO2, while the national combination had the lowest, with 17.850 tCO2. Materials proved to be the main source of emissions, followed by equipment and transportation, with averages of 89.50%, 7.67% and 2.83%. To offset the project's emissions, it would be necessary to plant 98 and 122 trees, depending on the national or international scenario, occupying an area of 0.059 to 0.073 hectares, respectively. These analyses and results are crucial for engineers seeking to understand and reduce the environmental impact of their work, in line with the companies' Environmental, Social and Governance Agenda, the UN Sustainable Development Goals to be achieved by 2030 and the transition to a low-carbon economy.
