The San Diego State University (SDSU) Library (San Diego, CA, USA) has made sustainability a key component of its new strategic plan. As such, we have mapped the work we are doing within all aspects of the library to document these efforts. The mapping was done through questionnaires to all library employees and a thorough analysis of the library website. This reflective review of current practice within the context of our strategic plan has provided a baseline for understanding our current strengths and determining where our future efforts in support of sustainability in libraries might be directed. The results were graphically presented in a series of posters to show how the University Library and its partners are focusing on the goals with the major areas where we are working toward each goal beyond what might be considered “traditional” library work. This culminated in an exhibit that challenged our community of students, staff, and faculty to critically consider ways in which they can contribute to achieving the goals and brought awareness to the UN SDGs and the work already being done in the library to achieve the goals. There have already been tangible results of this work, for example, the pursuit of the Sustainable Libraries Initiative Certification, the establishment of a library “Green Team”, and a commitment to being a leader in sustainability work in libraries in our region and at the national level. This poster will show the pathway to successfully mapping the UN SDGs in an academic library.
