Current methods for reaching and defining success in society are not sustainable. A major shift in society’s definition of economic success is required, and organizations represent a key leverage point in the transition to a sustainable economy. This research looks to practices within organizations with a sustainability purpose in an attempt to understand how their organizational culture creates an environment for continual strategic decision making towards sustainability. A combination of literature review and structured interviews were used to elicit the cultural practices of 18 organizations with a clear social and ecological sustainability purpose. The research confirmed the importance of organizational culture for maintaining alignment with a sustainability purpose by fostering motivation and commitment towards sustainability at both a collective and individual level in the organization. Eight overarching areas of practice were identified as being present in the organizations included in the study. The practices identified help organizations to act strategically and in the right direction towards sustainability on a daily basis, standing as a complement to the strategic prioritization model of the FSSD. / <p>giancarlo@pucci.cr</p>
