Implementing sustainable sourcing—Does purchasing need to change?

The implementation of corporate sustainability relies strongly on the purchasing function implementing sustainable sourcing. To advance understanding of this implementation, this paper offers a threefold contribution. First, it operationalises sustainable sourcing and addresses different possibilities of ways it can be implemented according to the company-specific emphasis on each of the three sustainability dimensions; i.e., economic, environmental, and social aspects. Second, this paper identifies, based upon stakeholder theory, internal and external stakeholders and their specific salience to drive the implementation of sustainable sourcing. Furthermore, the content of those salient stakeholders' claims is analysed concerning its impact on individual, company-specific sustainable sourcing profiles. Third, this paper explores how the purchasing function may need to change its internal and external relationships due to and in the course of implementing sustainable sourcing. Covering these three aspects, this conceptual paper concludes with a framework of testable propositions and offers several avenues for further research.
