How is the carbon footprint calculated?
Does the CO2 estimate that you provide include the manufacturing of the packaging? Also, is all transportation to the point of purchase included? I would expect the transport-related amount of CO2 to vary depending where the product is purchased so I can see this is a tricky question. I think it's important to try and get a true overall estimate, and I would be interested to see full details on how the estimate that you provide was calculated.
