Abstract: Education plays an enormous role within the economic development of the nation as it helps countries in accomplishing sustainable economic advancement with the assistance of its professors and their advanced leadership techniques that make a shift in university role and mission, thus, it is an imperative tool in raising social responsibility of the University Stakeholders. Therefore, the principal aim for this paper is to examine the effect of Sustainable Leadership measurements, i.e., leadership characteristics, leadership styles and leadership actions on Social Responsibility in the selected Lebanese private universities. Principally, it is hypothesized that Sustainable leadership factors have a positive effect on the Social Responsibility of the Lebanese Universities. For evaluating this correlation, I had conducted an online survey with a total sample of 300 Lebanese professors, out of which 180 completed questionnaires were obtained, during the period from February till June 2020. The reliability and validity of the dimensions are assessed through Confirmatory Factor Analysis (CFA) and the hypothesis are tested by using structural equation modeling SEM. The analytical results indicate that sustainable leadership characteristics and leadership actions have both a positive impact on the university social responsibility, in contrast to the leadership styles that do not have a positive impact on University social responsibility. Thus, this study implies the importance of leadership practices held in Private universities and its impact on USR educational, social and environmental dimensions to fulfill the society sustainable development.
