Climate change is a significant threat to human well-being (Lamb & Steinberger, 2017; Obradovich et al., 2018). Thus, mitigating this threat via behaving more sustainably is in humans’ interest (Clayton & Brook, 2005; Saunders, 2003). One of the strongest and most consistent predictors of sustainable behavior in the literature is sustainable attitudes (Balderjahn et al., 2013; Bleidorn et al., 2021; Dunlap et al., 2000). Most of the research on sustainable attitudes thus far has been conducted in Western samples, and very few studies have been done in sub-Saharan Africa. The goal of this study was to examine the structure and correlates of sustainable attitudes (SAs) in Kenya, Namibia, and South Africa and to compare these features to data from a U.S. sample.
