Electric vehicles (EVs) are considered a promising technology to mitigate air pollution and resource depletion problems. The emissions from the manufacturing process can cause severe health problems like chronic asthma and even death. Automakers and policy makers need to investigate the lifecycle emissions of EVs in different regions and then governments should decide if it is safe to establish EV production facilities in their country or whether it is more appropriate to import finished products. The objective of this study is to evaluate the air pollutant emissions produced by EVs and gasoline vehicles (GVs) during their life cycles under two technology scenarios. Life cycle analysis (LCA) was applied to quantify greenhouse gas (GHG) and non-GHG emissions. We assessed air pollution from vehicles in Japan, China, and the United Kingdom (UK). Results indicate that EVs do not necessarily decrease pollutant emissions. EVs can improve air quality and reduce emissions in countries where electricity is derived from clean energy resources.

Ghg Emission

Life Cycle Assessment (LCA) is a tool to calculate greenhouse gas (GHG) emissions of dairy production. A survey was conducted in 20 dairy farms at the governorate of Sousse. The present study aimed to evaluate environmental impact of milk production at the farm regarding GHG emission and energy consumption. In the 20 dairy farms total GHG emissions resulted in a mean of 0.63 +/- 0.2 kg CH4/kg ECM and forage can contribute with a means 0.35 Le kg CO2eq/DM. The main reductions in GHG emissions per kg of FPCM started from 2,347 kg per cow per year and then the reduction slowed down to stabilize at around 6,127 kg FPCM per cow per year.

Food Waste (FW) because of its composition is considered as an ideal feedstock for the production of biofuels and in particular bioethanol. The production of bioethanol from lignocellulosic materials has been studied over a long time. The process consists of the stages of pretreatment, enzymatic hydrolysis, fermentation and product recovery. However, the legal framework regarding biofuels has established specific environmental criteria for their production which are regularly updated. The most common tool for the assessment of the environmental performance of a process or product is the Life Cycle Analysis (LCA). In the present review, the results of LCA studies on the production of bioethanol from food waste are presented. Significant differences are observed among the studies in terms of the methodological choices made. Despite the high heterogeneity observed which does not allow a direct comparison among them, there is strong evidence that the production of bioethanol from food waste is an eco-friendly process which can substantially contribute to Green House Gas (GHG) emissions savings.
