Mobility and freight transportation are of worldwide importance. Presently they rely almost exclusively on fossil fuels. The 2015 Paris Agreement on Climate Protection calls for a drastic reduction of the associated CO2 emissions. As a prime choice for emission reduction of cars, presently battery-powered electrical vehicles (BEV) are widely favored. By law, the European Union uniformly classified all BEV as zero-CO2-emission vehicles, completely ignoring the source of the electrical energy and the very significant emissions due to battery fabrication. In order to expose this misleading regulation, we take a closer look at the CO2 footprint of a sedan BEV, if charged from the German grid, and compare this BEV to a conventional internal combustion engine (ICE), running on Diesel fuel. If a large BEV is equipped with a heavy, long-range battery and if this BEV is charged from the German grid, we find no CO2 reduction for a run of 200 000km, if compared to a modern Diesel engine. We offer some thoughts on a more detailed and proper analysis of future mobility concepts, the respective pros and cons, and on some of the alternative developments.
