“…The results showed that CO 2 , SO 2 , NO x , and PM2.5 emissions in the reservoir per kilometre are significantly reduced when the BEVs are charged during off-peak hours instead of peak hours. Wang et al [16] studied the uncoordinated emission reduction mechanism (e.g., CO 2 , NO x , SO 2 , and PM2.5). The results showed that a reduction of 78% of CO 2 , 94% of NO x , 98% of SO 2 , and 99% of PM2.5 is possible.…”

“…Of the few studies in technologies and engineering, most have shown that electric vehicles improve the environment and reduce PM2.5 emissions, CO 2 emissions, and greenhouse emissions by assessing the life cycle of electric cars, with a particular focus on BEVs and PHEVs (e.g., Rangaraju et al [10]; Timmers and Achten [11]; Alam et al [12]; Vilchez et al [13]; Xiong et al [14]; Ajanovic and Haas [15]; Wang et al [16]; Vilchez and Jochem [17]; Wang et al [18]; Andersson and Börjesson [19]; Zhao et al [20]; and Ma et al [21]).…”

Effect of Battery-Electric and Plug-In Hybrid Electric Vehicles on PM2.5 Emissions in 29 European Countries

The contribution of battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) to mitigating/reducing fine particulate matter (PM2.5) emissions was researched through a panel of 29 European countries from 2010 to 2019, using the econometric technique of method of moments quantile regression (MM-QR). This research is innovative by connecting the increasing use of electric vehicles with PM2.5 emissions and using the MM-QR to explore this relationship. Two models were estimated to analyse their contribution to reducing PM2.5 in European countries. The nonlinearity of the models were confirmed. The statistical significance of the variables is strong for the upper quantiles (75th and 90th), resulting from the effectiveness of European policies to improve the environment. Electric vehicles (BEVs and PHEVs), economic growth, and urbanisation reduce the PM2.5 problem, but energy intensity and fossil fuel consumption aggravate it. This research sheds light on how policymakers and governments can design proposals to encourage electric vehicle use in European countries. To achieve the long-term climate neutral strategy by 2050, it is imperative to implement effective policies to reduce the consumption of fossil fuels and promote the adoption of electric vehicles using renewable energy sources.

“…Unfortunately, the HGV vehicle class is the least promising for electrification because of the power requirements. When compared to the existing literature, the analysis in this paper on the West Midlands highlights a higher potential for emission reduction except for Beijing, as the study in [27] accounts for the progression to a cleaner energy mix.…”

“…A case study of Northern China by Wang et al discusses the large emissions reduction potential of EVs. In Beijing, the progression to a cleaner energy mix means that the promotion of EVs could reduce the total local emissions of both NO x and PM2.5 by more than 98% [27]. Nanaki and Koroneos performs a study in Athens, evaluating the effect of alternative fuel penetration, showed that changes in fleet composition lead to significant reductions in air and CO 2 emissions [8].…”

This study reports the likely real-world effects of fleet replacement with electric vehicles (EVs) and higher efficiency EURO6 vehicles on the exhaust emissions of NOx, PM, and CO2 in the seven boroughs of the West Midlands (WM) region, UK. National fleet composition data, local EURO distributions and traffic compositions were used to project vehicle fleet compositions for different roads in each borough. A large dataset of real-world emission factors including over 90,000 remote-sensing measurements, obtained from remote sensing campaigns in five UK cities, was used to parameterise the emission profiles of the studied scenarios. Results show that adoption of the fleet electrification approach would have the highest emission reduction potential on urban roads in WM boroughs. It would result in maximum reductions ranging from 35.0-37.9%, 44.3-48.3%, 46.9-50.3% for NOx, PM, and CO2, respectively. In comparison, the EURO6 replacement fleet scenario would lead to reductions ranging from 10.0-10.4%, 4.0-4.2%, and 6.0-6.4% for NOx, PM, and CO2, respectively. The studied mitigation scenarios have higher efficacies on motorways than on rural and urban roads because of the differences in traffic fleet composition. The findings presented will help policymakers choose climate and air quality mitigation strategies.

“…Higher AH also promotes the formation of particulate compounds. These particulate compounds are less absorbed in nature and prone to form PM 2.5 , which in turn also leads to an increase in AOD (Zhao et al 2019;Wang et al 2020;Zhang et al 2020). On the other hand, urban heating in winter is also responsible for the increase in AOD.…”
