Big Picture for Small Footprints
A calculator to suit you
Carbon Savvy recommends the Popular calculator, which takes around 5 mins, but you can also choose the Taster (1 min) or Full calculator (45 mins). Note the Taster is what it says, and does not give a very accurate footprint. You will need to know your rough spend on household bills and your average monthly travel.
