This article considers a few issues related to the environmental friendliness of electric cars. The increase in the concentration of greenhouse gases in the atmospheric air has led to the beginning of global warming. Only a significant reduction in the production of greenhouse gases can make the most significant contribution to climate change. According to the manufacturers of electric cars, their technology will reduce the amount of greenhouse gases entering the atmosphere, since they are not generated during the operation of this type of transport. But their figures do not take into account the emissions generated during the production of electric cars, or during the production of the energy needed to charge these vehicles.
