The United Nations 2030 Agenda for Sustainable Development places education and lifelong learning opportunities for all at the forefront of Sustainable Development Goal 4, thereby increasing the role of higher education institutions across the world. Higher education institutions have also significantly been impacted by technological advancements of the 21st century, necessitating the need to build resilience and respond with a sustainable approach. Conversely, studies on lifelong learning in the context of higher education institutions remain limited in Pakistan. Recognizing this fact, this study intends to examine sustainability in lifelong learning in terms of the courses offered, strategies used, challenges faced, and the sustainable leadership approach applied in Pakistan. This qualitative study employs the phenomenology approach to explore the perspective of lifelong learning center managers and uses a purposive sampling technique to select respondents from eight renowned universities in Pakistan. Thus, eight respondents who possessed a minimum one year of experience managing lifelong learning centers were asked questions in semi-structured interviews. Subsequently, the content analysis method was used to extract themes and analyze data. Finally, practical recommendations on how to improve the process and quality of lifelong learning have been made using the results of this study.
