“…As in the case of diesel, Figure 4b,e show that data do not support any statistical variation of SFC with vehicle age. Figure 4a,d additionally show that the SFC exhibit a log-normal distribution, which agrees with previous studies [26,48] and therefore, we can conclude that the observed high CNG consumption is not due to an irregular behavior of the vehicles.…”

“…Figure 3a shows the SFC frequency distribution for T3 and B2 diesel-fueled vehicles, which exhibit a log-normal distribution. The behavior agrees with previous studies [26]. Thus, from now on, we will use median values instead of average values to describe the tendencies of SFC.…”

“…Huertas et al (2022) [26] evaluated the SFC of 47 different HDVs in the variable topography (0-4000 masl) observed in Colombia, obtaining values between 50 to 80 L/100 km. In this study, they associated the SFC with its GVWR and concluded that neither altitude nor vehicle age influence SFC as long as they are properly mechanically maintained.…”

“…In this study, altitude was obtained using the GPS Visualizer Digital Elevation Model (DEM) www.gpsvisualizer.com/elevation (accessed on 31 August 2021). This methodology was validated by Huertas et al (2022) [26], who compared results from this tool with official values reported by government institutions. The operating conditions (fuel consumption, speed) of the diesel-fueled vehicles were obtained via the vehicle's engine computer unit (ECU), which reads the sensors that the manufacturers install on the engine to control its operation.…”

The energy consumption of a large sample of vehicles (6955) operating during the last 3 years under everyday conditions across Mexico was monitored via OBD-based telematics systems. A life cycle statistical analysis of the obtained data showed that, on average, 54 t diesel vehicles used for long-distance freight transport consume 44.25 L/100 km and emit 1513 g CO2e/km. When these vehicles are powered by natural gas, the energy consumption and the emissions of greenhouse gases (GHG) are increased by 23% and reduced by 0.8%, respectively. Using manufacturers’ data, these values reduce energy consumption by 16% and GHG emissions by 52% when they are electric. Similar observations were made for other vehicles sizes used for transporting goods and people.

“…Industry and transportation are significant contributors to climate change [1], where transportation accounting for 25% of global carbon emissions. Electric logistics vehicles (ELVs) are one of the best alternatives to conventional fuel logistics vehicles (CFLVs) interims of emissions reduction and economy [2]. However, ELVs have a higher purchase cost [3], especially due to the significant proportion of battery degradation cost, which decreases operational efficiency.…”

Electric logistics vehicles (ELVs) can reduce carbon emissions of logistics industry. However, the logistics company is reluctant to adopt ELVs due to the shortages of high purchasing cost, short driving range, and long charging time. This research studies ELVs leasing system which consists of an ELVs manufacturer, an ELVs rental company, and a logistics company. The influence of purchasing subsidies and Cap-and-Trade policy(C&T) on the ELVs leasing system is analyzed and compared. It is found that the logistics company prefers the subsidy policy when the driving range of ELVs is within a certain range. Otherwise, the logistics company prefers C&T policy. For the rental company and the manufacturer, when the subsidy is within a certain range, C&T policy is more profitable. Otherwise, the rental company and the manufacturer prefer the subsidy policy. If the emission reduction benefit is high enough, the C&T policy can lead to more emission reduction. Otherwise, the subsidy policy is better for the environment.
