Análise comparativa da emissão de co2 entre os modais hidroviário e rodoviário

Abstract

The climatic variations present in the daily life of Brazilians are notorious, the increase in temperature has generated changes in the ecosystem of planet Earth. It is known that road transport, as the main instrument of cargo transport in Brazil, has a high rate of diesel consumption and carbon dioxide (CO2) emissions per ton of cargo. In view of this, this article aims to calculate and compare the amount of CO2 released by burning diesel in cargo vehicles in the transport logistics sector between two different modes of transport, road and waterway, the latter considered an option to mitigate the impacts of climate changes resulting from the emission of Greenhouse Gases (GHG). Using hypothetical data, the number of vehicles to transport 285,275 tons of cargo was estimated according to the counting station of the National Department of Transport Infrastructure (DNIT) in the municipality of Alhandra, Paraíba. The calculation of fuel consumption and CO2 emissions was carried out for 9532 trucks, with variable load capacity from 15 ton to 55 ton. In relation to the waterway mode, 24 trains were used to transport the same volume of cargo. The results presented proved to be efficient, since waterway transport presented a relative reduction of 83.35% in CO2 emissions, when compared to road transport. Therefore, it is concluded that the waterway system, due to its greater cargo storage capacity, becomes a collaborative agent, as it requires fewer trips to transport the same volume of material.
