The MAGIC is in your hands!

  1. The thumb is carbon M·easurement. Without our thumbs, we would be unable to do many tasks.
  2. The pointer finger is A·nalysis. Analysing carbon data and activities helps us to point out carbon reduction potentials.
  3. The long finger is miti·G·ation. It reminds us that carbon reduction is a long journey.
  4. The ring finger is I·ntegration. New Zealand curriculum requires us to integrate climate change into our classrooms.
  5. The pinky finger is C·ommunication. Make a “pinky promise” on carbon neutralisation with school stakeholders.
