  How to use the calculator
Calculating your commuting carbon
— If your area is shown (and they include suburbs), click on it to get started.
— Drag your home marker to where you live, then your work marker to where you most often commute.
— Roll over the work marker to adjust settings for how you commute, and how often.
— Feel free to add commute routes to school, market, gym and restaurants to get a more realistic look at your carbon footprint.
— Challenge yourself by lowering the slider bar to a level below where you currently are. An exclamation marker will pop up, advising you to try changing how or how often you commute.
