Since 2019, sustainability has been included as a core value of librarianship by the American Library Association (ALA), which encompasses environmentally sound, economically feasible, and socially equitable practices. Furthermore, the Association of College and Academic Libraries (ACRL) Framework for Information Literacy in Higher Education has challenged academic libraries regarding sustainability. These challenges include intentionally including sustainability in instruction and research services, developing sustainability initiatives, and community engagement. Based on the recent work on the UN SDGs in the SDSU Library, the work is being done, but not clearly articulated. In addition, there is no benchmark for these efforts. Therefore, the goal of this certification program is to review sustainability practices in the SDSU Library through an extensive analysis of current practices and policies. This thorough analysis will provide a baseline of sustainability efforts to understand the strengths and challenges in this regard, and where to intentionally focus sustainability efforts in the future.
