“…The WTW method is composed by two distinct methods-Well-to-Tank (WTT) and Tank-to-Wheel (TTW) [78]. Publications also describe the TTW and WTW methods as Pump-to-Wheel (PTW) and Well-to-Pump (WTP) [79][80][81]. However, such a wide analysis from cradle to grave is hindered due to the necessity of including all the processes connected with extracting raw materials, producing fuel, and the supply chains.…”

This article has taken up an issue concerning the influence of the implementation of electromobility assumptions on reduction of air pollution in cities in terms of sustainable urban transport systems. The essential nature of the subject is confirmed by the following figures: transport is responsible for almost 25% of greenhouse gas emissions in Europe and is the main cause of air pollution in cities, almost 90% of city dwellers in the EU are exposed to levels of air pollutants deemed harmful by the WHO, and approximately 95% of vehicles on European roads still use fossil fuels. Therefore, the implemented transport policy, both in the international and domestic aspect of particular countries, is facing the need to significantly reduce the negative influence of transport on people and the environment. Electromobility has become one of the concepts that makes it possible to achieve this goal. Its main objective is to reduce emissions of harmful substances into the environment by deploying electric vehicles (EVs). Research conducted by the authors showed that public transport, apart from the obvious effect of decreased number of private vehicles and decreased congestion, can contribute to reduced air pollutant emissions and become a significant driver for the implementation of electromobility in cities. However, the achievement of this goal depends on taking appropriate actions not only in the transport branch but also in other sectors of economy. The following research methods were applied in the article: literature analysis, documentary method, case study, and mathematical methods. The research area was the city of Szczecin, Poland.

“…Hydrogen can be produced from both fossil and renewable sources [2] [3], but the majority is still derived from fossil reserves. The hydrogen first has to be extracted from the fossil source, then it can be used in a fuel cell to generate electrical power [4] [5]. Furthermore, problems related to storage [6], transport and security of hydrogen remain partially unresolved.…”

“…GHG emissions can be assessed using a WTW (wellto-wheel) analysis. The WTW analysis can be divided into two stages, from well-to-pump (WTP) and pump-to-wheels (PTW) [9]. A WTW analysis, Figure 1, assesses GHG emissions caused by all the processes of vehicles fuel life cycle [10].…”

“…A WTW analysis, Figure 1, assesses GHG emissions caused by all the processes of vehicles fuel life cycle [10]. The WTP stage includes processes such as raw material recovery, fuel production, fuel storage and distribution to filling stations [9]. The PTW stage includes fuel consumption during vehicle operation [11].…”

“…The PTW stage includes fuel consumption during vehicle operation [11]. Liu et al [9] carried out an analysis of energy use and WTW emissions, in which an FCEV (Toyota Mirai) was compared to a conventional gasoline-powered ICEV (Mazda 3). The authors concluded that, even being powered by hydrogen from a fossil-based production path (via steam methane reform from natural gas), 5% to 33% less fossil energy is used in WTW, and it produces 15 to 45% less greenhouse gases from WTW in comparison to the conventional gasoline ICEV.…”

The growing environmental concern has led to the search for new energy and powertrain systems. Electric vehicles (EVs) are emerging as a promising and sustainable alternative. EVs can be classified as Hybrid Electric Vehicles (HEV), Battery Electric Vehicles (BEVs), Plug-In Hybrid Electric Vehicles (PHEVs) and Fuel Cell Electric Vehicles (FCEVs).The Well-to-Wheel (WTW) analysis assesses the total primary energy consumed by the vehicle for each kWh of energy supplied to the vehicle's wheels, comprising all stages covered by the well-to-tank conversion path and, later, by the conversion of energy on board from the tank to the wheels.This study intends to carry out an analysis under the WTW perspective comparing EVs to conventional vehicles, under the viewpoint of GHG (greenhouse gas) emissions. A search will be carried out in the Scopus database, to select articles, between the years 2002 and 2020 (08/may), with the keywords: well-to-wheel and greenhouse gas emissions and electric vehicle.The electricity generation mix, the source of hydrogen production, the technologies for producing electricity or hydrogen, the losses during transmission and distribution of energy, the battery technologies, the attitude of ecological driving and the autonomy of the vehicle are all important factors that have great influence on GHG emissions. Only the introduction of electric vehicles in countries does not guarantee a reduction in GHG, being necessary to analyze the entire life cycle.
