How to take part

Pick one visible action rather than trying to do everything:

  • Join a cleanup, planting, repair, reuse or climate-awareness activity if one is available nearby.
  • Use the day to make one household, school or workplace habit easier to keep after the day is over.
  • Share specific environmental information instead of vague slogans.
  • If organising something, make it practical: time, place, supplies and a clear action.
