The article presents the results of a comparative analysis focused on responsible environmental behavior (REB), i.e. the conative dimension of environmental literacy, Czech and Slovak pupils of primary school. Within the study, a comprehensive Middle School Environmental Literacy Survey (MSELS) was used (McBeth et al., 2008), which has not yet been applied in both countries.
Responsible environmental behavior is identified through a subscale of MSELS which is oriented to REB. Based on the analysis of the results, the significant influence of gender, age, year and free time activities on the responsible environmental behavior of pupils was identified, with no statistically significant difference between Czech and Slovak pupils.
