<bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Background:</b> Sustainability is becoming an increasingly important issue in higher education (HE). Leadership statements in university sustainability reports (LSUSR) represent a unique genre for university leaders to communicate sustainability. This study aims to demystify the genre so that future leadership statements might be crafted with a greater degree of reflexivity. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Literature review</b> : Sustainability discourse in HE has been regarded as a legitimacy tool and an opportunity for image improvement for universities. Some studies have examined university sustainability reports, whereas there is a lack of studies focusing on the section of leadership statements. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Research question</b> : Are there any cross-cultural similarities or differences in terms of rhetorical moves and communicative purposes between the Italian LSUSR genre and the American LSUSR genre? <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Research methodology:</b> Using cross-cultural genre analysis, this study investigates the rhetorical moves of leadership statements produced by Italian and American universities. A move scheme is established and is used to annotate the sample texts. <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Results and conclusion:</b> The findings show that although the Italian and American LSUSR genres share the communicative purpose of establishing a sustainable image, the degree of discourse force exerting on this communicative purpose varies. The image-building discourse force appears to be more noticeable in the American leadership statements, which tend to use a wider range and a larger quantity of image-improving moves. The Italian subcorpus, on the other hand, seems to pay more attention to the genre function of report-introducing, which is not explicitly linked to image improvement. This article suggests that practitioners could consider the potentials of the LSUSR genre in developing an institutional culture of sustainability.
