Assessing greenhouse gas emissions and costs of Brazilian light-duty vehicles
With the growing concern on climate change, many governments are making efforts to substitute fossil-fuel passenger vehicles in order to meet the urgent need for low-carbon and renewable fuels. Electric and hybrid vehicles reflect the increasing interest in clean and energy-efficient options. Nevertheless, the large-scale adoption of full electric is challenged in some regions due to the higher cost of these vehicles. This research presents a framework to assess the total cost and greenhouse gas (GHG) emissions in three types of technologies currently present in Brazil: fully electric, hybrid, and combustion flex-fuel cars. Brazil's light-duty fleet is a compelling case because it is mainly composed of flex-fuel engine combustion cars. The country also has strong conditions to supply this fleet with ethanol at a large scale with competitive prices. According to our results, full electric can reduce GHG emissions by 85 % if compared to gasoline-powered combustion. Nevertheless, there is a 96 % higher cost per kilometer in comparison to flex-fuel combustion vehicles. Flex-fuel hybrid fueled with ethanol can reduce GHG emissions by 76 %. Combustion flex-fuel vehicles can reduce 59 % of GHG emissions with no additional cost when powered by ethanol. Our findings show that hybrid cars fueled with ethanol are a more cost-viable option for reducing the Brazilian light vehicle fleet carbon footprint in a short time. The methodological approach presented in this study can be replicated in other regions to analyze trade-offs between costs and GHG emissions, thus helping plan the most appropriate path for the light-duty fleet energy transition.
期刊介绍:
The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change.
Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
