ABSTRACT The main goal of this study is to examine the IFLA Green Library Award, which is given to green libraries and projects that have implemented a green strategy contributing to the attainment of Sustainable Development Goals (SDGs). Fifty-one libraries from 31 countries worldwide received awards during this examination (2016 – 2023). The results found that Europe had the highest proportion, with 15 countries winning the award 23 times (45.10%). Public libraries received the highest percentage of awards (60.78%), followed by university and national libraries at 11.76%. Regarding the best practices adopted by the winning libraries, the findings revealed that “education and outreach” as a best practice was prioritized by libraries in their awards with 31.37%, followed by “energy efficiency” (15.69%) and “green spaces” (13.73%). This study will probably contribute to enhancing the awareness among libraries regarding the IFLA Green Library Award. Additionally, the result of this investigation may encourage various libraries in developing countries to adopt the best practices of libraries that won the award by developing their strategy to be green based on their capabilities.
