This research note examines the purpose and role of the ATLAS special interest group (SIG) Animals in Tourism, Hospitality, and Leisure and its contribution to advancing animal justice in tourism studies and practice. Drawing on the case of this recently established academic community, it reflects on the SIG’s development, aims and future directions one year after its foundation. Using insights from a participatory workshop with members and guided by the principles of a theory of change, the note discusses how the SIG fosters ethical reflection, critical dialogue and transformative education across tourism, hospitality and leisure. While clarifying the SIG’s scope and roadmap, it also considers its potential as an intentional assemblage – a collaborative, values-driven collective connecting knowledge, care and action for reimagining human-animal relationships in tourism research and education.
