The study reported in this paper sought to examine the extent to which organisational leadership support and organisational culture explain the effect of regulation on sustainable procurement practice, as insights into this relationship is lacking in the extant literature. Useable survey data from 322 Ghanaian organisations were analysed using descriptive statistics, and structural equation modelling techniques. The analysis examined the nature of sustainable procurement practice in an African context, and the potential mediating effects of organisational leadership support and organisational culture (...) on regulation’s relationship with sustainable procurement. The findings reveal a moderate sustainable procurement practice in Ghanaian organisations, a significantly positive effect of regulation on related practices, and a mediation effect of organisational leadership support on regulation’s relationship with sustainable procurement. There was, however, no mediation effect relative to organisational culture. Potential relevance and implications of the study for theory and practice are explored in the discussion and conclusion sections. (shrink)

Effective implementation and committed practice of sustainable procurement remain a significant challenge for many organisations across the globe. This paper sought to understand the extent to which employees’ perceptions influence the practice of sustainable procurement in the context of a developing country where sustainability awareness is low. Drawing on the Diffusion of Innovation theory, procurement officers’ perceptions of sustainable procurement were examined relative to the attributes of complexity, compatibility and relative advantage. Empirical data from 322 Ghanaian organisations were analysed using (...) descriptive statistics and structural equation modelling to determine the nature of procurement officers’ perceptions of sustainable procurement and the effects of the perceptions on relevant organisational practices. The findings indicate that whereas perceptions of relative advantage did not significantly influence the practice of sustainable procurement, perceptions of compatibility had a significant positive effect, and perceptions of complexity had a significant negative effect on sustainable procurement. This study offers insights into the link between employees’ perceptions and organisational sustainable procurement practice, thereby providing a conceptual basis for effective management of the pertinent relationships with implications for enhanced ethical practices in procurement and supply chain management.
