Elaboração de inventário de gases de efeito estufa através da metodologia GHG protocol para implantação de um loteamento urbano no município de Bento Gonçalves

Abstract

The present study aimed to identify and quantify the sources that generate GHG in the implementation stage of the urban subdivision, located in the municipality of Bento Gonçalves, following the methodologies in Scope 1, the GHG protocol for mobile combustion sources and the SEEG Methodological Note -9 for carbon stock and emission and IPCC for carbon removal, due to change in land use and in Scope 3, the GHG protocol for transport and distribution (upstream) and the Ecoinvent database for ICV of the raw material. Total GHG emissions, for Scope 1 and 3, were 3,308.99 tCO2e. The main stage of GHG emissions, which presented 2,416.52 tCO2e, representing 76% of the total inventoried emissions, was the change in Scope 1 land use. In relation to Scope 3, the raw material category represented the majority of GHG emissions, with 475.31 tCO2e. This study was essential for the company, owner of the area where the subdivision is located, to know which GHG emission source categories were, as well as which had the largest share of emissions, enabling future studies to present measures to minimize and compensate for emissions generated in this activity.
