In the past years supply chain integration has become focus of interest, due to the discussion in the literature, that a positive direct relationship exists between higher supply chain integration and higher performance. Additionally, the environmental and social performance of supply chains gained much interest based on the new sustainability focus in the 21st century. The production of electrical and electronic equipment is one of the fastest growing global manufacturing activities. However, due to technological advancements, the quick obsolescence of electronics result in increased generation of waste of electrical and electronic equipment. Germany is one of the leading electrical and electronic equipment markets within Europe and is strongly affected by the EU directives and regulations, which aim not only to protect human health but also to improve the environmental performance of the electrical and electronic equipment operators in particular. Therefore, the environmental and social performance of German electrical and electronic equipment manufacturers is increasingly gaining importance. Respectively, the purpose of this study is to investigate what effect the depth of upstream supply chain integration has on the environmental and social performance of German electrical and electronic equipment manufacturers. This study is based on the quantitative research method. The required empirical data is generated through an online questionnaire, which has been sent to German electrical and electronic equipment manufacturers. An initial operationalization of upstream supply chain integration depth and environmental and social performance is used as a foundation for the questionnaire. It can be concluded that German electrical and electronic equipment manufacturers seem to have a coordinative upstream supply chain integration and presumably have a Abstract 4 moderate environmental and social performance. Furthermore, it can be assumed that the upstream supply chain integration depth has an effect on the environmental and social performance of German electrical and electronic equipment manufacturers.
