The project proved to be very interesting in several aspects. Students improved their competence in personal autonomy and entrepreneurship – as they took an active part in the learning process: during each task, students became active and autonomous learners, taking their own decisions, being innovative and taking risks (they decided on the content, negotiated the message, the means and the tools to be used).

Most participants considered the project quite innovative and considered that the technological tools used will help them in their academic and professional lives. 

Students felt to be active citizens, getting to undestand the real role of pollution and having to chance to act and help their own communities.

Due to very different phases of each school calendar (in some cases altered according to the epidemiological situation of each country/region), the activities had to undergo some changes in their genesis. Schools adapted the layout to their reality and sometimes activities were taken into action in different stages.

Students felt that interaction among international teams was little, which will be considered in future projects.
