21. Does your household use a water-efficient washing machine (or no washing machine)?
Conserving water might not relate directly to a safe climate, but if we want to grow our own food and plant carbon-absorbing trees we need enough water for that. Households in the drier parts of Australia might also want to have water-efficiency measures in place in preparation for a possibly drier future.
A washing machine with a 5-star rating is significantly more water-efficient than one with 3 stars. When you next need to buy a new one, go to savewater for water efficiency (and energy efficiency) ratings for washing machines. In addition, if you use cold water for most loads of washing, you are avoiding the carbon emissions caused by heating water.
