Estimativa de emissão de gases de efeito estufa na operação do sistema ferroviário da região metropolitana de João Pessoa - Paraiba, Brasil.

Abstract

The present study aimed to inventory Greenhouse Gas (GHG) emissions from the rail system of the metropolitan region of João Pessoa in the base year of 2016. The methodology of the Brazilian GHG Protocol version 2016 was followed to quantify emissions. The issuing sources were organized according to the operational limits classified in scopes 1, 2 and 3. The total emission in the inventoried year was 1,035.76 tCO2e and 73.26 tCO2 biogenic. The source that most contributed to the emissions was the railway combustion with 981.05 tCO2e, followed by the generation of electric energy 22.67 tCO2e. Considering the interdisciplinary nature of this research, it is understood that the study of the atmospheric impacts of the João Pessoa train system served as a parameter for the design of strategies and techniques to mitigate air pollution in the State of Paraíba, such as improving the quality of life for generations to come.
