“…Whilst ESD is considered a formal commitment to making HEIs themselves more sustainable through initiatives such as sustainable campus, sustainable procurement and so on, EE denotes the initiatives that aim to incorporate sustainability into the curriculum (Boley, 2011;Figueir o and Raufflet, 2015;Kohl et al, 2022;Th€ urer et al, 2018;Wu and Shen, 2016). Although SHE is frequently used in the literature, no comprehensive definition is available (Berjozkina and Melanthiou, 2021;Boley et al, 2014;Deale, 2013;Deale and Barber, 2012;Liu et al, 2017;Millar and Park, 2013). Whilst authors from hospitality restricted sustainable education to the practices specific to teaching, learning, pedagogy, curriculum, leadership and collaborative research, researchers from other disciplines used it to denote the whole institutional approach towards sustainability (Albareda-Tiana et al, 2020;Franco et al, 2019;Kohl et al, 2022;Velazquez et al, 2005; Zal_ enien_ e and Pereira, 2021).…”
