“…It is important to note that demographics and environmental goals at a range of levels of abstraction have been related to engagement in environmentally sustainable behavior in the past: This includes free-market ideology at the broadest level of abstraction (e.g., Heath & Gifford, 2006;Lewandowsky, Gignac, & Vaughan, 2013), environmental identity at a medium level (e.g., Fielding, McDonald, et al, 2008;Fielding, Terry, et al, 2008;Sparks & Shepherd, 1992) and beliefs in anthropogenic climate change at the most specific level of abstraction (e.g., Bord, O'Connor, & Fisher, 2000;Gifford, 2011;Leviston & Walker, 2012). Since the self-concordance of sustainable behaviors is partially based on the relationships these behaviors may have with environmental goals, we wanted to rule out the possibility that it is these relationships with environmental goals that are driving the behaviors, rather than the overall self-concordance, and thus we need to control for these variables.…”
