Sustainability literacy: faculty, staff, and students as agents of change There is no doubt about the need for enhancing sustainability literacy among faculty, staff and students at the university level in the years and decades to come. Yet, despite this broad consensus and the need for higher education to equip students with the ability to understand and solve this century's many sustainability problems, it remains frustratingly difficult and rather ambiguous to articulate more precisely what enhancing such literacy means in practice. There is no standardization of program structure or curricula across sustainability in higher education (SHE)and many would agree that such conformity would be undesirablebut this creates immense challenges for assessment and comparisons. There are no widely accepted scoring systems or checklists for measuring the effectiveness of courses or programs in advancing sustainability literacy. Despite the emergence of such tools as Sulitest to measure student progress (Décamps et al., 2017), critics question the efficacy of such approaches (Kuehl et al., 2021). Recently, in their critique of Sulitest, Kuehl et al. (2021) identified the more fundamental challenge for sustainability literacy as one of "coherence," where "as others have suggested with the concept of sustainability itself, sustainability literacy may not exist as a coherent domain of knowledge" (Kuehl et al., 2021, p. 5).Despite such lack of coherence and the need to better enhance sustainability literacy, various groups within SHE are currently focused on better articulating competencies and learning outcomes and not building sustainability literacy. Therefore, while we applaud these efforts, we acknowledge that they address only a slice of the sustainability literacy challenge.Given the above, in 2020, the Symposium "Sustainability Literacy: Faculty, Staff, and Students as Agents of Change" was organized to better understand the state of play in sustainability literacy. Hosted by the College of Charleston in Charleston, SC, USA, in February of that year, the transdisciplinary Symposium brought together lecturers, researchers and practitioners from a wide spectrum of the social and natural sciences, the humanities and other domains of higher education, representing sustainability-asknowledge in the widest sense [1]. For purposes of the Symposium, sustainability literacy was broadly construed to include curriculum innovation, empirical work, activities, case studies and practical projects where sustainability is understood as the integration of three dimensionsenvironmental protection, economic development and social justice. Within this the literacy part was (and for purposes of this special section of the journal, is) "skills and knowledge" as a specific baseline and, for some, also includes competencies (Evans, 2019).It was posited that to the extent to which sustainability literacy exists or is being practiced, it has not been sufficiently foregrounded and systematically articulated in higher educational learning settin...
