Abstract: In this study, the aim was to examine the amount of CO2 emissions from the use of a tram and an automobile as a mode of transportation. In addition, two different equations were used to calculate the power consumption of the tram. The novel equation is an innovative, empirical equation that does not neglect the average curve resistance, unlike the original equation, and does not include the power consumption that is caused by internal consumption. The fluctuations in the current were not hypothetical but actual measurements when the equation was built. As a result of the calculations made for different scenarios to measure CO2 emissions, it was seen that the automobile produced between at least 11.6 (novel equation) and 26.39 (original equation) times more CO2 amount per passenger-km (CO2/pkm) compared to the tram. This provided the opportunity to demonstrate how the type of transportation and the number of passengers affect this CO2/pkm rate by using theoretical and empirical methods. Thus, the objective of the emission values targeted in the Paris Agreement will be achieved.
