“…In the model, we assume that conditions required in Directive 2000/53/EC [36] in terms of coefficients of reuse, recovery, and recycling rate are fulfilled. The percentages of material in the total weight of the car, qm i , for FFC and EC are adopted from Wang et al [37]. Namely, these authors found the values of the percentages of material for 2009, and predict these values for 2020.…”

Reducing CO 2 emission is one of the major environmental challenges for transportation. One way to solve this problem is to replace old cars that use fossil fuels (petrol, diesel) with new electric cars. In this paper, the existing model for calculating well-to-wheels CO 2 emission during the life cycle of the car (fossil fuel car and electric car) is upgraded. The developed model is used for comparing optimal lifetime and optimal car's kilometers driven during a lifetime in the replacement process of a fossil fuel car with a new electric car. We find that reducing CO 2 emission depends on the type of fossil fuel, and the weight of fossil fuel cars and electric cars. Changing petrol fossil fuel cars with lower weight electric cars have the greatest potential for reducing CO 2 emission. However, the introduction of electric cars does not achieve a significant reduction of CO 2 emission in countries where electricity is primarily produced in thermal power plants, i. e. in countries with a high emission factor of electricity production.

“…Considering the total life cycle of ICE, EV, and FCV vehicles, the advantages of EVs and FCVs in terms of energy consumption, emission, and well-to-wheel efficiency remain debated and depend on the electricity mix, hydrogen production method, and other factors. 23 Life cycle analysis has been implemented to compare the ICEVs, EVs, and FCVs. While analyzing manufacturing, driving, and installing infrastructure of EVs in Japan, it resulted in less CO 2 , NO x , and CO emissions than ICEVs.…”

Summary Today's gasoline engines use a group of new technologies to fulfill emission legislation and at the same time improve fuel consumption with excellent drivability performance and increase specific power and torque output. One technology group focuses on the improvement of efficiency at low loads which includes variable charge motion, variable valve actuation, GDI stratified, and homogenous injection, and the other group shifts the engine operating point towards more efficient operating areas by using super/turbo‐charging, downsizing the engine volume and choosing a longer gear ratio (down‐speeding). This paper provides a theoretical analysis of the proposed active modular internal combustion engine concept (AMICES) which was done for the first time in the literature. AMICES is a specific proposed engine concept with a fully variable load and has compression pressure control on extremely downsized engines as part of an unsynchronized boosting and turbine recuperation system. The AMICES concept in its nature offers constant torque over a full range, high transient response, no pumping losses which increases low load efficiency, and highly efficient in‐cylinder cycle. The cycle was analyzed where it was found that respectable improvement in efficiency could be obtained when compared with conventional gasoline engines (for the considered case, increase in theoretical efficiency was found to be up to 18% which in real operating conditions is expected to be below 10%). Optimization was also performed in order to find optimal cylinder air filling, ie, volumetric efficiency. The main advantages, ie, benefits of the novel proposed concept, were also analyzed, and further possible development steps of the AMICES were introduced. Finally, the proposed concept has potential for favorable implication related to the reduction of gasoline engine fuel consumption and the reduction of harmful CO2 emissions.

“…BEV'lerin kullanımı ile sera gazı emisyonlarının azalacağını vurgulayan benzer çalışmalar da mevcuttur (Zhou, Ou, & Zhang, 2013). Buna karşın, başka bir çalışma ise BEV'lerin sera gazı emisyonlarını arttıracağı sonucuna varmıştır (Wang et al, 2013). EV'ler için LCA yapıldığında diğer çevresel kazanımların küresel ısınma potansiyelinin ötesine geçtiğini bilmek gerekmektedir.…”

Transportation sector enables the transfer of goods and services that forms the basis of the economy and the work of people. It supports global productivity and is a key for economic growth. On the other hand, transportation is largely based on fossil fuels and generates greenhouse gas emissions. Moreover, it releases other pollutants and creates local air pollution. Although the air pollutant emissions of road transport of Turkey have decreased over the years due to new emission standards, greenhouse gas emisions of the same sector in Turkey have been sharply increased. Therefore, there is an urgent necessity of focusing on sustainable transport strategies to reduce emissions from transportation sector. The sustainability of the road transportation depends on alternative fuels and electric vehicles. Alternative fuels like biodiesel and bioethanol have already been used in motor vehicles for many years. Using alternative fuels reduce the release of air pollutant emissions except nitrogen oxides. However, alternative fuel production generally depends on local farming and not common every part of the world. Electric vehicles are a hope for road transport sustainability. Hybrid electric cars consume less fossil fuel and full electric cars run on only by electricity. If electricity comes from an alternative energy source, transportation by electric vehicles will be much more sustainable since it does not produce any greenhouse gas or air pollutants. This paper briefly discusses motor vehicle air pollution problem and gives some information about Turkish road transport sector emissions. Furthermore, it reviews sustainable road transport options mainly by focusing on alternative fuels and electric vehicles. Also, there exist some suggestions for policy makers about the sustainability of transportation sector.
