“…Empirical definition of environmental upgrading is it "occurs when a firm, within a particular GVC, improves its environmental performance through changes in technological, social and organizational processes and by extension avoids or reduces its overall environmental impacts" (Khattak et al, 2015, p. 331). A limited number of research has been conducted so far and all are exploratory in nature with the aim to understand the construct of environmental upgrading along with its processes and core dimensions in GVCs (see De Marchi, Di Maria, & Micelli, 2013;De Marchi, Di Maria, & Ponte, 2013;Goger, 2013;Khattak & Stringer, 2016;Khattak et al, 2015;Poulsen, Ponte, & Lister, 2016). All these researchers emphasize the role of lead firms in environmental upgrading in GVCs, which supports our view that governance mechanisms are crucial factors influencing upgrading.…”
