Green supply chain management (GSCM) and green supply chain practices (GSCP) refer to a variety of activities and initiatives implemented by an organisation in an attempt to reduce their impact on the natural environment. As highlighted by Testa and Iraldo (2010), the reasons towards GSCM may be ethical and/or commercial (e.g., gaining a competitive advantage by signalling environmental concern). However, despite its growing diffusion and success, a number of factors are still hampering GSCM adoption by companies. In recent years, GSCM and sustainability issues have been attracting rising attention among researchers and practitioners, basically due to increased environmental concerns and to an ever-competitive environment. As remarked by Min and Kim (2012), this growing interest sparked a series of new lines of research dealing with various supply chain activities that have important environmental implications, ranging from manufacturing to logistics and transportation. Focussing on logistics and freight transportation, several sources (e.g., Davies et al., 2007; Marchet et al., 2009) agree that this industry is presently facing a rising competitive pressure, mostly due to a combination of factors, such as the ongoing process of globalisation and internationalisation, the increasing need for cost reduction and service improvement, and the progressively more severe constraints related to the external environment. To address these requirements, the logistics service industry has
