The study of environmental beliefs is important in the prediction of pro-environmental behavior and in the perception of environmental problems. For over a decade, research on environmental attitudes in Mexico has been increasing, and many of such works has been done using the New Environmental Paradigm, NEP, by Dunlap and Van Liere (1978). The purpose of this study was to continue the analysis of environmental beliefs among the Mexican population and to research on the potential influence academic training has upon such beliefs. The study included 300 university students from Mexico City who responded the questionnaire (NEP scale), and a tripartite composition was obtained. The results are similar to those obtained in previous studies in terms of factor division. However, correlations compared to other studies are significantly different. Differences were also found in the natural balance factor when the students’ academic area was considered.
