E-mobility is treated as emission-free. Generally, this sentence can only be true in a very small range. Namely, about selected pa-rameters and in a very limited area. An example of this is the measurement of CO2 emissions in the immediate vicinity o

For the third time in the history of humankind, it is trying to implement e-mobility. There is a reasonable hope that this attempt will succeed this time. E-mobility is generally regarded as a zero emission. This sentence can only be true in a very s
