“…The majority of research aimed at increasing individuals' performance of environmentally sustainable behaviors has generally taken one of two approaches (for reviews of workplace interventions see Osbaldiston & Schott, 2012;Unsworth, 2015;Young et al, in press). First, studies based on psychological theories such as Theory of Planned Behavior (e.g., Fielding, McDonald, & Louis, 2008), the Values-Beliefs-Norms model (e.g., Stern, 2000), Self-Determination Theory (e.g., Pelletier, Tuson, Green Demers, Noels, & Beaton, 1998), or a normative or leadership approach (e.g., Andersson et al, 2005;Cialdini, 2003;Graves, Sarkis, & Zhu, 2013;Kim, Kim, Han, Jackson, & Ployhart, 2014;Walls & Hoffman, 2013) have aimed to motivate people by influencing their environmental and altruistic values, perceived social and personal norms related to environmentally sustainable behaviors, knowledge of climate change, and attitudes towards the environment and climate change (e.g., Bamberg & Moser, 2007;Black, Stern, & Elworth, 1985;Dono, Webb, & Richardson, 2010;Fielding, Terry, Masser, & Hogg, 2008;Han, Nieuwenhijsen, de Vries, Blokhuis, & Schaefer, 2013;Stern, Dietz, & Guagnano, 1995;Sussman, Greeno, Gifford, & Scannell, 2013).…”
