In 2020, vehicle sales decreased dramatically due to the COVID-19 pandemic. Therefore, several voices have demanded a vehicle subsidy similar to the “environmental subsidy” in Germany in 2009. The ecological efficiency of vehicle subsidies is controversially discussed. This paper establishes a prognosis of the long-term environmental impacts of various car subsidy concepts. The CO2 emissions of the German car fleet impacted by the purchase subsidies are determined. A balance model of the CO2 emissions of the whole car life cycle is developed. The implementation of different subsidy scenarios directly affects the forecasted composition of the vehicle population and, therefore, the resulting life-cycle assessment. All scenarios compensate the additional emissions required by the production pull-in within the considered period and, hence, reduce the accumulated CO2 emissions until 2030. In the time period 2019–2030 and for a total number of 0.72 million subsidized vehicles—compensating the decrease due to the COVID-19 pandemic—savings of between 1.31 and 7.56 million t CO2 eq. are generated compared to the scenario without a subsidy. The exclusive funding of battery electric vehicles (BEVs) is most effective, with an ecological break-even in 2025.

补贴概念对德国汽车销售的环境影响

到2020年,由于COVID-19大流行,汽车销量急剧下降。因此,有几种声音要求与2009年德国的“环境补贴”相类似的汽车补贴。对汽车补贴的生态效率进行了有争议的讨论。本文建立了各种汽车补贴概念对环境长期影响的预测。确定受购置补贴影响的德国车队的CO 2排放量。CO 2的平衡模型发展了整个汽车生命周期的排放。不同补贴方案的实施将直接影响车辆人口的预测构成,从而影响最终的生命周期评估。所有方案都补偿了在考虑的时间段内生产引入所需的额外排放,因此减少了直到2030年的累计CO 2排放。在2019-2030年期间,总共有72万辆补贴车辆—补偿了由于COVID-19大流行而减少了排放量-节省了1.31到756万吨的CO 2当量。与没有补贴的情况相比产生的。电池电动汽车(BEV)的独家资金是最有效的,到2025年将实现生态收支平衡。
