“…In the second stage, based on the number of taxis in 2014, which was 9749, and the predicted number of taxis in 2020 (10,182), there is a 4.4% increase in the number of taxis in 2020 compared to 2014. Therefore, using the same percentage of increase and based on the total travelled kilometers in 2014, which was 490 million km [14], the total expected travelled kilometers in 2020 by taxis could be estimated (511.56 million km).…”

Recently, developing sustainable public transportation systems has been highlighted by decision makers and transportation agencies, due to the development of urban areas and the related environmental problems. Implementing new vehicle technologies has been introduced as an appropriate alternative to the conventional taxis. Hybrid electrical vehicles (HEVs) have been the potential candidates for replacing the conventional taxis, since they are more eco-friendly than conventional ones and even more reliable than electric vehicles (EVs) as a mode of public transportation. In this study, current and future environmental impact assessments have been determined for the taxi fleet in the West Bank, Palestine, and the implications of using new vehicle technologies (hybrid taxis) as a replacement of the conventional taxi fleet have been investigated. In order to perform this study, firstly, the data of the number of taxis for the period of 1994–2018 have been collected and a prediction model for the future number of taxis has been developed. The expected total amounts of consumed fuels have been then estimated. Finally, the current and the future N2O and CO2, and emissions, have been estimated and the expected influences of hybrid taxis have been determined. The results of the analysis have concluded that replacing 50% of conventional taxis with a hybrid fleet could achieve 42.3% and 28% reductions in N2O and CO2, respectively, in the next 10 years. A 395% increase in CH4 could be obtained due to the higher amount of CH4 that is produced by the gasoline combustion compared to the diesel fuel, since hybrid vehicles have gasoline-based engines (GHG in terms of CO2-equivalent could be increased by 28.2%).

At the beginning of the work on the effects of global warming and climate change in the international area, there are efforts to reduce exhaust emissions. Because fossil fuel is depleting and exhaust emission gases emitted to the atmosphere are rising rapidly, energy efficiency is on the agenda in transportation. Therefore, automotive developers and scientists have undertaken new research in the automotive sector. Hybrid electric vehicle technology is one of the important studies that these researchers continue. In the hybrid electric vehicle technology, the hybrid engine is aimed to give the best results in terms of exhaust emission, fuel consumption and maintenance costs compared to other internal combustion engines, and at the same time the hybrid engine is aimed to perform better than other internal combustion engines. General information about the hybrid electric vehicle technology as one of the new and alternative technologies in these study is provided. In addition, information was given about exhaust emission, emission standards and fuel consumption. Comparisons were made between the hybrid engine and other internal combustion engines.

“…The transportation sector is one of the highest consumers of fossil fuels and one of the main contributors to greenhouse gas (GHG) emissions. About 17% of all the consumed hydrocarbon fuel and 23% of all the carbon dioxide (CO 2 ) emissions into the atmosphere are accounted for by vehicles [1].…”

During the last two decades, the development of sustainable transportation systems has been highlighted as a key element in solving environmental problems related to climate change and impacts on greenhouse gases. Globally, the transportation sector has become one of the main contributors to these environmental problems. Thus, the environmental impact assessment of this sector and the implications of new vehicle technologies have begun to be considered as first steps for any long-term future strategies in this sector. In Palestine, the lack of environmental data related to the transportation sector and the absence of studies that address the new vehicle technologies (such as hybrid vehicles) and their future implications make it difficult to set up any future strategies or plans. In this study, the current and the future environmental impacts of the transportation sector have been assessed, and the future implications of hybrid vehicles have been determined. The gross domestic product (GDP), population, and the number of vehicles for the period 1994–2018 have been used to develop an auto regressive integrated moving average (ARIMA) prediction model for the future number of vehicles. Then, the total traveled kilometers and the total consumed fuels (by diesel and gasoline vehicles) have been predicted. After that, the current and future (2020 and 2030) greenhouse gas (GHG) emissions, including CO2, N2O, and CH4, have been estimated. Finally, the future implications of hybrid vehicles, based on two scenarios (10% and 20% hybrid vehicles) have been estimated. The results have showed that the estimated CO2, N2O, and CH4 emissions from the transportation sector in 2020 are 4,842,164.5, 213.8, and 445.8 tons, which are very high, and even much higher than the total national emissions of 2014 (the only officially available data). Moreover, in 2030, replacing 20% of internal combustion engine vehicles (ICEVs) by hybrid vehicles would lead to 4.66% and 13.31% reductions in CO2 and N2O, respectively, as compared to 100% ICEVs, while the CH4 emissions will increase. However, the overall CO2-equivalent will decrease by 5%; therefore, a more sustainable transport system will be achieved.
