In Israel, youth movements (YMs) comprise a main agent for nonformal education of youth and a youth-engagement framework in which civic engagement can be expanded to address environmental challenges. A major source of sociocultural diversity among YMs is their religious identity, based on the categorizations of secular, religious, and ultraorthodox. We compared, among these groups, the environmental literacy (EL) characteristics of "young-guides" and YM-leaders' perspectives of sustainability in relation to their YM. Differences among groups were found in the young-guides' EL: members of secular YMs demonstrated greater EL and openness to including pro-environmental activities within their YM. "Judaism as a platform for addressing sustainability" emerged as a major theme from leaders' interviews. Implications for meaningful incorporation of sustainability and EE within the groups are discussed.
