“…In contrast to the literature on private sector organisations, comparatively little research has investigated SP practices in the context of the public sector. Existing research has tended to focus on the development of tools to assist green procurement policy implementation (Coggburn, 2004;Günther & Scheibe, 2005;Li & Geiser, 2005;Swanson, Weissman, Davis, Socolof, & Davis, 2005), on how sustainability can be encouraged when the public sector buys from suppliers in specific industries, such as construction (Hall & Purchase, 2006), IT (Matthews & Axelrod, 2004), food (Rimmington, Smith, & Hawkins, 2006), and timber (Bull et al, 2001) or in particular areas of the public sector (Thomson & Jackson, 2007). Other notable studies report a case study of sustainable public procurement in Belfast City Council (Murray, 2000), and describe the history and present use of government contracting as a tool of social regulation (McCrudden, 2004).…”
