Abstract
Adventure tourism operators have historically drawn upon a range of broad, multi-purpose sustainability frameworks to provide experiences that are more ecologically and socially just. However, these efforts have been hindered by the need to interpret and translate large volumes of diverse sustainability guidance, which is often unclear or prohibitively complex in terms of how it can be applied to specific adventure operations. This paper aims to address this issue by (1) identifying the primary types of sustainability guidance available for adventure operators; (2) critiquing the benefits and limitations of each form of guidance; and (3) making recommendations for research and practice. The inquiry employed a systematized review methodology, informed by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to interrogate the various forms of sustainability guidance available to adventure tour operators. The analysis revealed three broad categories of guidance: Paid Memberships and Certifications, Guidelines and Frameworks, and Pledges and Declarations. The findings demonstrate how each of these categories brings distinct benefits and limitations to operators, depending on their size and scope of provision. Implications for practice are offered, in terms of how existing frameworks might be adopted and/or alternative approaches to integrating and monitoring sustainability initiatives developed. Suggestions for further research include examining adventure travellers' and operators' perceptions of the three different categories of guidance found in the current study, and the ways in which operators engage with this guidance.
