This report is the result of an independent study on the economic and environmental impact of e-commerce across Europe led by Oliver Wyman with the support of Logistics Advisory Experts, a spin-off of the Institute of Supply Chain Management of St Gallen University. It has been conducted over a 12-week period and was commissioned by Amazon. The analysis is based on official statistics up to 2019 (unless stated otherwise) and publicly available information. The study does not use any private information from Amazon or other retailers or transport operators. Consumer behavior data is based on proprietary surveys conducted by Oliver Wyman in 2020 across Europe (France, Germany, Italy, Spain, United Kingdom).
