“…As far as past studies on sustainability in higher education are concerned, research has been carried out from several main perspectives. The first perspective has focused on management issues in sustainability of higher education which consists of topics such as sustainability assessment tools (Findler et al, 2018;Drahein, De Lima and Da Costa, 2019;Caeiro et al, 2020), sustainability reporting (Ana, Laura and Garcia-Benau, 2018;Coco, Remmer and Elisa, 2019;Sahar, Udo and Hossein, 2019), and challenges in managing sustainability in higher education (Molthan-Hill, Dharmasasmita and Winfield, 2016;Aleixo, Leal and Azeiteiro, 2018;Tormo-Carbo, Seguí-Mas and Oltra, 2018). The second perspective centers on the definition and elaboration of sustainable development competencies comprising those required by the university faculty in teaching the sustainability content and necessary competencies for student achievement (Grant, Lips-Wiersma and Soebagio, 2017;Foster and Stagl, 2018;Lavey, 2019) The third perspective is related to the implementation of higher education for sustainable development which addresses the purposes, scopes, and challenges of sustainable development associated with teaching and learning (Leal Filho and Dahms, 2018;Molderez and Fonseca, 2018;Michel, 2019).…”
