The adoption of sustainability standards within organizations represents one of the most significant challenges that firms face. This qualitative based study draws on the core-periphery thesis of organizational change and the resource-based view of the firm to explore the three adoption architectures firms can use to integrate green certification scheme standards into their business operations. As a result, we examined the nature of the linkages between the different adoption mechanisms, and how such linkages might influence a firm’s sustainability performance. The study demonstrates that organizational attributes, previous experience with a sustainability agenda and the degree of fit between the externally generated sustainability standard and the prevailing business practices can affect the abilities of firms to integrate sustainability standards into their organization structures and thus their sustainability performance. Hence, this paper opens new avenues for sustainability certification researchers to look at the various configurations of standards adoption architectures, and also for practitioners to broadly embrace both institutional and organizational exigencies relevant to the internalization of certification standards
