Electronic commerce has become increasingly popular in recent years and has experienced an additional boost from the COVID-19 pandemic. In 2020, worldwide online sales increased by 27.6% to 4.280 trillion US dollar, while total global retail sales declined by 3%. The share of global online sales in total retail sales thus corresponds to approximately 18%. For the US, the increase in online sales from 2019 to 2020 was as high as 44%, with e-commerce sales accounting for 21.3% of total retail sales in 2020 . E-commerce cannot be assigned to a specific research area; studies on this topic are anchored in various fields. There are studies that focus primarily on the barriers and drivers of online shopping at the level of consumer behaviour . However, they usually do not link this to the impact on the number of trips or the level of resulting emissions. In addition, there are qualitative studies that take a closer look at the mobility effects associated with online retailing . Changes due to e-commerce at the infrastructural level  or in the transport of goods  are also examined in more detail. The studies listed represent only a small selection. This shows the relevance of this topic in scientific research.
