Abstract
Changes have stood out among the global issues of greatest interest in recent decades. Among the classes of pollutant emissions, fugitive emissions are responsible for 5% of Greenhouse Gas (GHGs) emissions in Brazil. In 2015, 195 countries gathered at the United Nations Conference on Climate Change (COP21) where each member nation, through the Intended Nationally Determined Contributions (INDCs), stipulated its own goals and commitments for the climate agreement, whose central focus is to limit the increase in global average temperature by up to 2°C. Brazil is a signatory to this agreement and its proposed emission reduction targets are 37% by 2025 and 43% by 2030. In this context, fugitive emissions began to be extensively studied in industrial plants. However, there are no records of studies on mobile sources, even taking into account that the aging of couplings and exhaust pipes in vehicles can cause gas leakage. Thus, this work proposes to elucidate, in an unprecedented way, through experimental investigation, the existence of fugitive emissions in buses regulated by Euro V standards. For this, statistical methods were used to define the minimum representative sample. Along the exhaust, fugitive gases were enclosed and channeled to begs, which were later sent for analysis in the laboratory. Chemiluminescence and infrared methods and a Horiba PG-300 analyzer were used to analyze the samples. The results were compared with the parameters of the current legislation, where it was observed a direct relationship between vehicle age and increased fugitive gas emissions.
