The VDA-Politikbrief illuminates current topics in the automotive industry. The new issue 01/18 explains why "technology neutrality" is the guiding principle and prerequisite for an efficient path towards sustainable mobility. This applies in particular with respect to the CO2 regulation post 2021 for passenger cars and light commercial vehicles. We also provide new data and facts on the current debate about air quality in German cities. We show why fiscal policy action is required in Germany. And finally we analyze the possible Brexit effects on the German automotive industry.
