Education is one of the key instruments to achieving global sustainability. In fact, sustainable development has to be integrated into higher education curricula. One of the difficulties of this challenge is to know if students are able to achieve the basic skills, something that is extremely important in emergency management. Thus, assessment of student's work outside the classroom, non-formal curriculum, is essential to adjust the subjects of education for sustainability to the philosophy of the European Credit Transfer System (ECTS) credits. This pilot study details the measurements of the self-reported time spent by the students in different activities associated with sustainability, study habits, integration of new technologies and use of support material. Moreover, the students' motivation and satisfaction with the course was also analysed. In this regard, two challenges were identified: teamwork and getting a better study organization.
