What drives sustainable procurement? Insights from the theory of planned behavior

A fundamental research question is what leads some organizations, but not others, to be sustainable in their procurement operations. Extant theoretical frameworks, while valuable, do not fully reflect the nuances of decision-making in procurement operations. We aim to illuminate the role of individual attitudes, capabilities, and behavioral intentions in actualizing sustainable procurement. We find that sustainable purchasing behavior is predominantly shaped by behavioral intention, that is, willingness to pay for sustainability. This behavioral intention is significantly influenced by individual attitudes and capabilities in addition to awareness of consequences and perceived corporate social responsibility engagement but, interestingly, not by individual subjective norms.
