Environmental literacy is represented by levels of environmental knowledge, attitudes, sensitivity and environmentally responsible behaviour. In this study, the relationship between these components of environmental literacy and their relationship with possible determinants (gender, outdoor activities) were tested. An analytical tool developed by the author was applied and the data were analysed by Structural Equation Modelling (SEM). The results of the study provide evidence of a relatively close relationship between environmental attitudes, sensitivity and responsible environmental behaviour. Similarly, a significant link between environmental literacy and outdoor activities was also demonstrated. In the case of gender, differences in Attitudes, Sensitivity, Behaviour and Outdoor Activities were identified, with girls achieving higher values.
