Nova SBE and the Students’ Union have joined the Cascais Oxygen Program, an initiative dedicated to promoting and protecting nature and biodiversity in the Municipality of Cascais through voluntary actions. As part of the program, participants adopt a plot in the Natural Park of Sintra-Cascais, where members of the Student Association are responsible for its care over a five-year period. Their duties include planting, eradicating invasive species, manually clearing vegetation in the caldera, mounding, watering, and controlling invasive species. In 2021, the Students’ Union expanded participation to include not only students but also staff and faculty, opening the initiative to the wider community.
