With this paper, we want to demonstrate the current state of knowledge of Education for Sustainable Development (ESD) in the case of environmental engineering teachers in Colombia (South America). To determine the state of knowledge, a structured survey with 21 multiple-choice questions with the Likert scale scheme was used. The survey was applied to 39 university teachers who teach in environmental engineering programs, from 13 different universities. The survey also verified whether the Environmental Education (EE) trend is still being used by teachers and therefore transmitted to students. It was possible to identify a general lack of knowledge of ESD by teachers and, on the contrary, a strong preference for EE. This is largely due to the fact that, since 2003, Colombia has a policy that promotes EE, which has not had updates or derogations that give way to the ESD. It was found that teachers consider that ESD is important in the field of action of environmental engineers and that this educational trend must be part of the curriculum. Therefore, although the country has strong roots and promotes EE, environmental engineering professors see ESD as an alternative that would strengthen the skills of future engineers.
