到2050年，世界道路上的车辆数量预计将增加到29亿辆，因此必须采取措施减少交通运输的二氧化碳排放量。电池电动汽车（BEV）可以帮助实现这一目标。本研究旨在确定不同国家纯电动汽车运行产生的CO2排放量，并将这些CO2排放量与基于内燃机（ICE）的类似车辆的排放量进行比较。本研究选择了四个基于ICE的车辆，并根据这些车辆的规格对BEV进行建模。通过模拟运行建模的BEV以确定其能量消耗。他们的能源消耗与不同国家发电组合的CO2强度数据相结合，以揭示BEV运行产生的排放。将BEV的CO2排放量与基于ICE的对应物的CO2排放量进行比较。结果表明，对于中国和印度以及其他具有类似高CO2强度的国家，除非发电的CO2强度大大降低，否则BEV将无法实现CO2排放的有意义的减少，而BEV渗透率的增加实际上可能导致更高的CO2排放。
With the number of vehicles on the world’s roads expected to grow to 2.9 billion by 2050, steps must be taken to reduce the CO2emissions from transport. Battery electric vehicles (BEVs) can help achieve this. This study aimed to determine the CO2emissions stemming from BEV operation in different countries and to compare those CO2emissions to the emissions from similar vehicles based on internal combustion engines (ICEs). This study selected four ICE-based vehicles, and modeled BEVs based on the specifications of each of these vehicles. The modeled BEVs were run through a simulation to determine their energy consumption. Their energy consumption was combined with data on the CO2intensity of the power generation mix in different countries to reveal the emissions resulting from BEV operation. The CO2emissions from the BEVs were compared to the CO2emissions for their ICE-based counterparts. Amongst the results, it was shown that for China and India, and other countries with a similarly high CO2intensity, unless power generation becomes dramatically less CO2intensive, BEVs will not be able to deliver a meaningful decrease in CO2emissions and an increase in the penetration of BEVs could actually lead to higher CO2emissions.
