Prof. Julia Hartmann’s work revolves around the identification and quantification of potential benefits that firms can derive from their endeavors to enhance environmental and social conditions within their supply chains. Through extensive empirical studies, she strives to bring clarity to the expectations of stakeholders, demonstrating to firms that taking proactive action aligns harmoniously with the interests of relevant stakeholders. 

The collapse of the Rana Plaza building in Bangladesh in 2013 drew worldwide attention to working conditions in the textile industry. Prof. Hartmann analyzed the tragedy’s impact on sustainable supply chain management practices within the fashion and apparel industry (Hartmann, 2021). Her work covers the expectations of consumers regarding firms’ responsibilities to ensure human rights and environmental protection in their global value chains (Wolf, 2012; Hartmann and Moeller, 2014; Benoit, Hartmann et al., 2022), as well as the influence of less developed economies or non-democratic regimes on environmental management (Hartmann and Germain, 2015; Hartmann, Germain et al., 2015; Hartmann and Uhlenbruck, 2015; Hartmann, Inkpen et al., 2022). Additionally, Prof. Hartmann’s research has shown that responsible sourcing reduces adverse impacts (Eggert and Hartmann, 2021) and improves the firms' performance and resilience to disruption (Hartmann and Germain, 2015; Hartmann and Vachon, 2018; Eggert and Hartmann, 2022).  

Prof. Hartmann was invited to the German Bundestag to share her insights on the intricate relationship between global transportation and the pressing climate crisis. Her voice was amplified through radio, print, and digital media covering human rights and environmental protection issues. As a guest at practitioner conferences, she shared her findings to catalyze industry-wide transformation.
