Inter-School Sustainability Challenge

Key People and Partners Involved

  • School administration
  • Students and teachers
  • Participating schools
  • Local municipalities
  • Environmental NGOs

Description of the practice

The Inter-School Sustainability Challenge is designed to foster environmental awareness and action among students by turning sustainability into a collaborative and competitive effort. Schools agree on a timeframe and a set of sustainability goals, such as reducing waste, saving energy, promoting eco-friendly transportation, or organizing community clean-ups. Each school forms a sustainability team to lead the initiative and track progress.

Throughout the challenge, schools earn points for implementing sustainable actions, engaging the local community, and demonstrating measurable impact. Activities might include installing recycling stations, hosting awareness campaigns, planting trees, reducing single-use plastics, or organizing collection drives for waste paper, used batteries, and aluminum cans. Regular updates and friendly rivalry help maintain momentum and enthusiasm among participants.

At the end of the challenge, results are shared and celebrated. The winning school may receive a symbolic prize or recognition, but all participants benefit from the positive environmental changes and strengthened community ties. The challenge encourages long-term thinking and often leads to permanent improvements in school policies and student behavior.
