Based on a review of Major League baseball team websites, this study provides insight to how teams are communicating commitment to sustainability principles and practices through an analysis of self-presented sustainability content. Websites for thirty-one (31) teams were examined for content relative to Elkington’s (1997) triple bottom line dimensions. Global Reporting Initiative (GRI) indicator codes and definitions were constructs for the model and aligned to social, environmental, and economic principles for categories of sustainability practices. Researchers found that, although teams are including sustainability information at some level in their websites, the majority highlight social issues on their home pages and subsequent pages; communication about environmental factors varies by league and tends to reflect league-wide initiatives, and economic issues are largely not communicated. The study suggests that, while teams are communicating a commitment to sustainability primarily at a social level to their constituents, they may be missing an opportunity to leverage environmental and economic sustainability initiatives.
