Impactos da introdução dos veículos elétricos nas emissões de gases do efeito estufa: uma breve revisão

Abstract

Electric vehicle technology is increasingly gaining industry attention automotive. The race to meet aggressive emissions reduction targets CO2 is causing some countries to consider banning the sale of vehicles with internal combustion engines and, at the same time, encourage electric cars (called zero emission vehicles), as these still have low market share. In this context, this study aimed to make a brief review of the literature regarding the introduction of this new type of vehicle and its real impact on the level of greenhouse gas emissions. It was noticed that, although many consider that the electric vehicle does not emit pollutants, they generate an increase in energy consumption and, to generate electricity, there is emission pollutant and this pollution generated varies according to the raw material used. Therefore, it was possible to observe that, even considering indirect emissions, in most studies, electric cars help to reduce the emission of CO2. However, the result needs to be analyzed regionally, as each country has a different energy matrix. Some remarks were made regarding the other pollutants and the unexpected results of incentive policies.
