Abstract
Much of the effort to control greenhouse gas (GHG) emissions in the transportation sector has focused on the use of biofuels and the promotion of technological innovations in propulsion systems. Therefore, studies that compare the environmental impacts associated with different vehicle technologies are necessary to identify the pros and cons for the environment when using a particular system. Thus, this work developed a comparative study of GHG emissions associated with the life cycles of battery electric vehicles (BEV), hybrid electric vehicles (HEV), and conventional vehicles, the last two evaluated with ethanol and gasoline type E27. Life Cycle Analysis principles were applied to quantify the inputs and outputs linked to the climate change category. Initially, available data was gathered from the literature corresponding to the life cycle stages of the vehicles in question, as well as the fuels used. Then, we sought to meet the structure of the ISO 14000 series of standards. The inventory was analyzed using Microsoft™ Excel™ software. The functional unit chosen was 1 km traveled. The results show that HEV with ethanol presented itself as the best technology, climatically followed by BEV.
