This is a study of how businesses might influence other businesses to move towards sustainability. Two health club businesses in North America actively participated and were selected because of their private ownership structureand their similar size and services. One health club had significant experience with working towards sustainability, and the other had little or no such experience. This is a descriptive study that applied an Active Research model in which researchers andbusiness management teams all actively participated. Five cycles of learning and adaptation are documented, including three work sessionsand initial and final interviews. Data from these five cycles were analysed to assess changes in perceptions of and knowledge about sustainability in business. We have concluded that the least experienced health club demonstrated sound increases in their knowledge and perception about sustainability. In addition, itis actively considering implementing select practices in itsfacilities that represent movement towards sustainability. The club with significant sustainability experience did not demonstrate increased knowledge or perceptions about sustainability, but did perceive value in the business-to-business sustainability discussions.
