Sustainable thinking and going green are undoubtedly on the agenda worldwide. The International Federation of Library Associations and Institutions (IFLA), adopted the United Nations Agenda 2030 to demonstrate the key role of libraries as engines for sustainable development. The purpose of the keynote is to motivate and encourage academic libraries to take a leading role in their communities to achieve the Sustainable Development Goals (SDGs) of Agenda 2030 and to stimulate further research on the topic. The keynote will identify outstanding examples of sustainable libraries from different countries with a focus on academic libraries that took part in the IFLA Green Library Award competition or published their project as a SDG story on the Library Map of the World. The examples given will clearly show how libraries address the demands across all SDGs. Libraries are the guarantor for access to reliable information. They open the doors to quality education and critical thinking. Both are more than ever relevant facing fake news in the post-Covid era. Academic libraries and librarians are invited to join a global movement to act as exemplars, educators, and enablers for sustainable development.
