This paper explores which trips currently made in Germany by personal motorized transportation could be replaced by e-scooters and what effect this would have on greenhouse gas emissions. This potential for substitution is estimated on the basis of data from the national household travel survey in Germany. Our analysis shows that 13% of the daily car trips, corresponding to 2% of the car kilometers in Germany, are suitable for replacement. Based on these results, we show that saving potentials of greenhouse gas emissions are heavily dependent on the general conditions of the specific use case (e.g. e-scooter lifetime) and the type of vehicle replaced. At best, a saving potential of about 5.8 kt of CO_2eq per day could be achieved when trips with conventional cars are replaced by e-scooter driving. However, if battery electric cars are replaced, an increase in emissions may even occur under certain conditions.

本文探讨了目前在德国通过个人机动交通工具进行的哪些旅行可以被电动滑板车取代，以及这将对温室气体排放产生什么影响。这种替代潜力是根据德国全国家庭旅行调查的数据估算的。我们的分析表明，每天有 13% 的汽车出行，相当于德国 2% 的汽车公里数，适合更换。基于这些结果，我们表明温室气体排放的节约潜力在很大程度上取决于特定用例的一般条件（例如电动滑板车的使用寿命）和更换的车辆类型。最多可节省约 5.8  kt CO _2eq当传统汽车的出行被电动滑板车取代时，每天可以实现。但是，如果更换电池电动汽车，在某些条件下甚至可能会出现排放量增加的情况。
