Temperature-dependency of Environmental Higher Education Ranking Systems

Many higher education stakeholders criticize the existing Environmental Higher Education Ranking Systems for not taking environmental factors which a given university operates in into consideration in processing the university portfolio and to group universities based on environmental factors similarities. This study intended to evaluate one of these environmental factors the Average Annual Temperature [AAT] and its impact on the ranking of universities. We studied the relationship between the AAT and two Environmental sustainability Higher education ranking systems [ESHERS] which are the University of Indonesia Greenmetric [UIGM] and Times Higher Education University Impact ranking [THEUIR]. We aim to find to what extent should UIGM and THEUIR methodologies consider the countries average annual temperature in evaluating the progress of the universities. We collected data of the overall university scores of 2020 ranking for the two ESHERS along with the AAT values for countries host these universities from the Listfirst website We used the linear regression technique to figure out any relationships between AAT and university ranking scores. The initial results show the AAT of a country doesn't have any impact on a university ranking operates in that country. The residual plot shows that many reseals are left without explanation by the model and the fit figure shows that there is no linear pattern in the dependent variable.
