“…On the side of incentives, granting recognition to schools that incorporate sustainability considerations in all aspects of their operations, such as in "green" labelling programmes like Eco-schools (Foundation for Environmental Education, n.d. [134]), can be an effective form of external pressure to raise students' environmental literacy (Boeve-de Pauw and Van Petegem, 2017 [135]; Byrne et al, 2023[136]; Cincera and Krajhanzl, 2013 [137]).
