The current study aims to understand if sport organizations can utilize environmental sustainability (ES) efforts to increase revenue in addition to saving money. To do this, fans of the Philadelphia Eagles were surveyed. Findings indicate fans were willing to pay an average of US$6.50 in the form of a sustainability fee to help the organization implement an environmental initiative. Furthermore, this study found that nearly none of the prevailing thoughts on predictors of fan behavior significantly positively predicted fans’ willing-ness to pay an environmental sustainability fee. The findings of the current study challenge the conventional theoretical thinking with respect to fan behavior. Furthermore, respondents in the current study were equally likely to financially support the sustainability efforts of their favorite team no matter their income, loyalty to the team, personal values, or conative loyalty associated with environmental sustainability. Theoretically, the current study advanced the triple bottom line theory, the Contingent Valuation Model, and the Model of Sport Fan Sustainability Behavior.
