The evolving role of academic libraries in fostering sustainable communities, particularly through climate change literacy, has gained prominence recently. A questionnaire study with 203 academic library staff in Jordan highlighted these libraries' significant role in advancing Sustainable Development Goals (SDGs). The findings underline libraries as key facilitators of climate literacy, stressing the need for diverse strategies in today's socio-academic context. Libraries are urged to enhance their collections for greater inclusivity, provide extensive climate-related staff training, and focus on sustainable operations to demonstrate environmental commitment. The study advocates for targeted outreach, the use of advanced digital tools, and embracing a global mindset that respects linguistic and cultural diversity. To effectively promote climate change literacy, libraries require strategic planning, deeper user engagement, capacity building, and a dedicated effort to enhance climate literacy.
