摘要

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 CO_2 emissions from transport. Battery electric vehicles (BEVs) can help achieve this. This study aimed to determine the CO_2 emissions stemming from BEV operation in different countries and to compare those CO_2 emissions 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 CO_2 intensity of the power generation mix in different countries to reveal the emissions resulting from BEV operation. The CO_2 emissions from the BEVs were compared to the CO_2 emissions for their ICE-based counterparts. Amongst the results, it was shown that for China and India, and other countries with a similarly high CO_2 intensity, unless power generation becomes dramatically less CO_2 intensive, BEVs will not be able to deliver a meaningful decrease in CO_2 emissions and an increase in the penetration of BEVs could actually lead to higher CO_2 emissions.
