Quantificação de gases de efeito estufa em transporte e lançamento de concreto: um estudo baseado nas diretrizes da ABNT NBR 14064-1:2022

Abstract

The Civil Construction sector is responsible for a large part of greenhouse gas emissions in the world. Goals and maneuvers to mitigate or even eliminate these emissions have been defined in recent decades so that the planet does not suffer from an increase in temperature, such as the Paris Agreement, which aims to limit the increase in the Earth's temperature to 1.5ºC. It is necessary to analyze the processes and technologies that are being used in the sector and understand what can be done so that the emissions generated can be mitigated. Life cycle and meta-analysis studies are being developed in several countries to analyze possible solutions in the process and production of materials in the sector. With the objective of quantifying GHG emissions from the transport and concrete pouring process of a residential building located in the city of Pato Branco-PR, using ABNT NBR ISO 14064-1 as a basis, the work presents the total emissions for two CO2, CH4 and N2O gases and the results in GWP (CO2e).
