The Digital Library Federation (DLF) is a network of member institutions and a robust community of practice advancing research, learning, social justice, and the public good through the creative design and wise application of digital library technologies. The DLF serves as a resource and catalyst for collaboration among digital library practitioners, scholars, and students.

DLF is committed to fostering a culture of sustainability within the digital library community. However, specific details on their sustainability practices, such as carbon footprint calculations or ESG reports, are not readily available. The organization emphasizes the importance of sustainable digital practices and encourages its members to adopt environmentally friendly technologies and methodologies.

DLF's initiatives often focus on the long-term preservation of digital content, which inherently supports sustainability by ensuring that digital resources remain accessible and usable for future generations. They also promote open access and the sharing of resources, which can reduce the need for redundant data storage and processing, contributing to a more sustainable digital environment.
