Comparative Life Cycle Analysis of Electric and Conventional Vehicle in Bangladesh.

Abstract

In many parts of the globe, electric cars are being promoted as a means to drastically improve urban air quality while also cutting greenhouse gas emissions. Utilizing a Life Cycle Analysis approach, this study examines and compares the potential environmental impacts of several types of vehicles in Bangladesh, including electric vehicle, gas, compressed natural gas and diesel. With this study, the researchers want to perform an in-depth investigation of a wide range of environmental influence categories. An environmental and economic Life-Cycle Assessment of conventional and electric vehicle technologies is performed in this article, with particular emphasis on the primary energy sources and greenhouse gas emissions throughout the vehicle running phase. A thorough evaluation of the Electrical mix was carried out, taking into consideration the contributions of each kind of main energy source. When compared to equivalent internal combustion engines throughout the course of a vehicle's lifespan, battery electric vehicles met the aim of lowering greenhouse gas emissions in 2015, but this covers a greater human health impact among several other environmental side effects. On the other side, electric vehicles have the potential to significantly increase human toxicity, freshwater ecotoxicity, freshwater eutrophication, and metal depletion, mostly via the usage of the car supply chain, as well as other environmental impacts. The assumptions made about the power supply, energy consumption throughout the utilization phase, vehicle longevity, and battery replacement schedules have an impact on the findings. It takes teamwork to improve the environmental profile of electric vehicles, including efforts to reduce supply chain impacts and to promote renewable energy sources in Electrical infrastructure planning and decision-making.
