Environmental education scholars have argued for the need to focus on identity as a more predictive factor than attitude of individuals' environmental behavior. We examine individuals' decision-making as a mediating process between identity and behavior. University undergraduates (N = 299) were surveyed, with a select sub-sample interviewed. As expected, environmental identity was correlated with pro-environment behavior (recycling). However, students with lower pro-environmental identity also recycled regularly. Similarly, analysis of decision-making revealed most students, regardless of their environmental identity, do not think much when recycling. Environmental structures such as presence of recycling bins surfaced as a powerful influence on pro-environment behavior.
