Of course you can, but make sure you know what your online calculator does. The free ones often only account for a few categories of activity and can miss up to 80% of your full carbon footprint - the better online calculators do cover most of the categories but you're on your own. By joining Go Climate Positive you will get an independent assessment of your full carbon footprint, help to set meaningful reduction targets and support to keep your carbon action plans on track. On top of all that, you get a certificate that gives your customers confidence that you are committed to reducing it.
