Energy efficiency has an increasingly important role to play in responses to climate change at both an individual and organisational level (IPCC, 2014). Personal consumption patterns (consumer behaviour, household energy use, dietary changes etc.) are identified as crucial elements in the move towards lower carbon emissions, thus efforts to promote energy-saving behaviour change form an important part of the policy agenda (Brounen et al., 2012;Geller et al., 2006). Unfortunately, even when people are motivated to change their behaviour with regard to energy saving, many lack sufficient understanding to make appropriate decisions (Gardner and Stern, 2008;Lorenzoni et al., 2007), or fail to change their habitual responses to similar situations even in the light of altered intentions (Kastner and Matthies, 2014).Most energy saving activities are of the low-effort, low impact variety, and even more numerate individuals are only slightly more likely to gauge accurately the amount of energy saved by different actions (Attari et al., 2010). This suggests that enhancing energy literacy throughout all levels of education has an important role to play in encouraging energy saving behaviour (Liu et al., 2015). As DeWaters and Power (2013) The role of education in ensuring a more sustainable future is not in doubt: the recent United Nations 'Decade of Education for Sustainable Development' (DESD) (UN 2005(UN -2014 has provided a focus for the development of a range of educational initiatives with the overarching goal of integrating the values of sustainable development into all aspects of learning and, ultimately, encouraging behaviour change (UNESCO, 2015). Universities have a key role to play, as has been highlighted consistently in policy documents. However, despite a global movement that has repeatedly emphasised the role of universities through research, campus greening and education for sustainability (Sterling et al., 2013;Wals, 2014), there is less evidence of the impact of such endeavours on students' practical actions such as personal energy saving behaviours.This may seem surprising as across Higher Education (HE), 'campus greening' initiatives (particularly energy-saving measures by university estates teams) have progressed rapidly (Leal Filho, 2010).Embedding education for sustainability (EfS) within the curriculum has been slower and more problematic and yet there is strong potential for universities to influence students' energy saving behaviour. In theory, sustainability across the campus and the curriculum are inter-related (students learn not just from the formal curriculum, but also from the informal and hidden curricula, through social
