Environmental transgressions involve breaking environmental protection laws (EPL), constituting a singular kind of illegal conduct from a legal and psychosocial perspective. EPL encompass a wide variety of behaviours which is very broad-ranging and, therefore, require different evaluation criteria. This study analyzes the responses of 196 university students living in an area of high environmental protection to a questionnaire encompassing 20 common environmental transgressions in their immediate surroundings, which they had to evaluate using 14 scales. The results show that the dimensions of the participants' perceptive space are consistent with those obtained through other samples, episodes, scales and statistical procedures. These dimensions enabled 85% of transgressions to be correctly classified into the three categories commonly used by public administrations, with more accurate predictions found for Transgressions against the Natural Environment than for Pollution/Contamination and Construction Activities.
