I only boiled what I needed. That may be something that most people already do, but the truth is my kettle gets filled whether I am making a cup of tea, or a pot of coffee generally. Out of habit I just fill my kettle every single morning without thinking.
From now on I plan on being more mindful of this.
The little book says that completely filling the kettle for one cup of tea releases an unnecessary 125 cups of CO2. May not seem like much of a deal but every little bit makes a difference inlightening our Carbon Footprint. I"ll keep sharing new little changes I am making on my blog. I'm of course doing all the obvious things but there is always more we can do.
