Sustainability planning, development, management, and marketing is becoming more common, especially in the face of complex issues such as overtourism and climate change. Various stakeholder groups are salient in these planning and management processes. One important stakeholder group in a tourism destination is business owners and managers. Based on Upper Echelons Theory (UET), the intent of this paper is to test the relationships between sustainability attitudes and incorporation of sustainability practices in businesses among business owners/managers in a destination community. A survey of business owners/managers in a major destination was conducted. Of the 730 unique business contacts, 262 completed the survey after three email reminders timed over several weeks for a response rate of 36 percent. Findings suggest a link between business managers’ attitudes toward sustainability and the implementation of sustainability actions in their businesses. The paper supports the premises of UET and outlines implications for practice.
