Previous studies on environmental evaluation suggest that women have more altruistic preferences and therefore value the surrounding environment more than men. This study examined the relationship between environmental concerns and altruistic preferences in a simple way. As a result, unlike findings from previous studies, both variables did not correlate with each other. Moreover, gender differences in altruism were confirmed, but those in environmentalism were not. A possible explanation for such discrepancies is that altruistic preferences are context-specific and not invoked until altruistic decisions are defined based on environmental issues.
